By way of example, the computing device 110 includes, but is not limited to, a personal computer, a laptop, a smartphone, a tablet, a portable wearable device, and the like. The specific structure of the computing device 110 will be described in detail later, and will not be described again here.

Scene 100 may also include scanning device 130 . The resource transfer code projected by the computing device 110 may be within the scanning range of the scanning device 130. The scanning device 130 may scan and identify the resource transfer code, thereby performing corresponding resource transfer operations, such as funds, physical or virtual items, points, virtual Transfer operations of various resource objects such as props.

In addition, optionally, the scenario 100 may also include a server 140. In some embodiments, the resource transfer processing solution provided by the present disclosure can also be deployed on the server 140 or partially deployed on the server 140 and partially deployed on the computing device 110 . User 120 may access services provided by server 140 via computing device 110 via network 160 . For example, the server 140 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or it can provide cloud services, cloud databases, cloud computing, cloud functions, cloud storage, and network services. , cloud communications, middleware services, domain name services, security services, CDN, and cloud servers for basic cloud computing services such as big data and artificial intelligence platforms. In addition, it should be understood that the server 140 is only shown as an example, and in fact, other devices or combinations of devices with computing capabilities and storage capabilities may also be used instead or in addition to provide corresponding services.

Optionally, scenario 100 may also include database 150. In some embodiments, the data required or generated to implement the resource transfer processing solution provided by the present disclosure may be partially or fully stored in the database 150, such as characteristic images of target objects, account information of resource accounts, information related to resource accounts, etc. associated characteristic information, etc. For example, the database 150 can be an independent data storage device or device group, or it can also be a back-end data storage device or device group related to other online services.

As mentioned earlier, with the development of computer technology, in scenarios involving resource transfer, such as payment scenarios, transactions or exchange scenarios for physical or virtual items, etc., instead of the delivery process of resource entities, scanning Resource transfer code (such as payment code, etc.) to complete the transfer process of corresponding resources. In addition, emerging solutions for resource transfer through methods such as face swiping, fingerprint swiping, and palm swiping have gradually emerged. These solutions help further improve the convenience of resource transfer. However, when hoping to use the above emerging solutions, it is often necessary to upgrade the software and/or hardware of the scanning device or related processing system. For example, the code scanning device and the related processing system can be modified to support the above emerging solutions, or the code scanning device or the related processing system can be connected to another device to support the above emerging solutions, where, This other device can be used to perform the emerging scenarios described above. In related technologies, when connecting a code scanning device or a related processing system to another device, the connection can generally be made through a connection cable (such as a USB cable) or Bluetooth. However, supporting emerging solutions through software and/or hardware upgrades requires a lot of additional manpower, time and other costs, and may have an adverse impact on the stability and security of the original equipment and system; the connection method through cables will increase the number of hardware lines The cost, additional space occupied, and the connectivity of line connections are easily affected by human activities; the connection method through Bluetooth is easily interfered by other signals, thus affecting the stability of the connection. Therefore, these connection methods are less than ideal.

Based on the above considerations, the applicant proposed a new resource transfer processing solution, which can make up for the shortcomings of the above technical solution.

Schematically, FIG. 2A shows an example flowchart of a resource transfer processing method 200A according to some embodiments of the present disclosure. Illustratively, the image processing method 200A may be applied to the scene 100 shown in FIG. 1 , for example, may be deployed on the computing device 110, the server 140, or a combination of the two in a form such as an application program. As shown in the figure, the resource transfer processing method 200A may include steps 210 to 230, specifically as follows.

In step 210, a characteristic image of the target object may be obtained, and the characteristic image may include characteristic information associated with the target resource account. For example, the target object may refer to the user or the user's characteristic part, such as the palm, face, fingerprint, iris and other body parts; the characteristic image of the target object may refer to the image containing the user or the user's characteristic part; the characteristic information may refer to the image that can be used For information that identifies the user's identity, the user can pre-enter corresponding feature information and associate the feature information with a resource account, where the resource account can be the user's resource account, or the resource accounts of other users related to the user. , a resource account can refer to an account that stores certain types of resources (such as funds, points, physical or virtual items, virtual props, etc.). Exemplarily, in the example where the target object is the user's palm, the feature image may be an image including the user's palm, and the feature information may be, for example, the size ratio of the palm, palm print distribution, etc.; in the example where the target object is the user's face, , the characteristic image may be an image including the user's face, and the characteristic information may be, for example, facial contour, distribution of facial features, shape of facial features, etc.; in the example where the target object is the user's fingerprint, the characteristic image may be an image including the user's fingerprint, and the characteristic information may be The shape of the fingerprint, etc.; in the example where the target object is the user's iris, the feature image may be an image including the user's iris, and the feature information may be the color, texture, etc. of the iris. Optionally, a camera may be used to obtain a characteristic image of the target object, or a characteristic image of the target object may be received from other devices. When using a camera to obtain a characteristic image of a target object, the presence of the target object can be automatically detected, and when the target object exists, the camera can be used to capture an image of the target object; alternatively, the user can also manually select whether or not the target object is in place. Take an image.

In step 220, a resource transfer code associated with the target resource account may be obtained based on the feature image, where the resource transfer code may represent verification information required to perform a resource transfer operation for the target resource account. Optionally, the resource transfer code can be a one-dimensional code, a two-dimensional code or other forms of code generated according to various preset rules. For example, the resource transfer code may include information related to the target resource account, such as the identification of the target resource account, the identity of the user, verification information set by the user, etc. Alternatively, the resource transfer code may be randomly generated and related to the target resource account. The association code (the association may be time-sensitive, for example, and may be recorded at, for example, a backend server). The verification information represented by the resource transfer code can refer to any information that can identify the target resource account and perform resource transfer operations through this information, such as the identification of the aforementioned target resource account, the identity of the user, verification information set by the user, and other information. Or it can be a randomly generated string associated with the target resource account, etc. This verification information enables the resource transfer operation for the target resource account to be performed by scanning the resource transfer code. The resource transfer operation includes at least one of the following: transferring a certain amount of a resource from the target resource account, and transferring a certain amount of resources to the target resource account. A certain amount of a certain resource is transferred to the account. For example, the resource transfer code may be a payment code, a collection code, etc.

In step 230, a light beam can be used to project the resource transfer code within the scanning range of the target code scanning device, so that the target code scanning device scans the resource transfer code and performs a resource transfer operation for the target resource account based on the verification information. Optionally, the light beam used to project the resource transfer code may be a red or other color laser beam, or may be other types of visible light beams, or may also be an invisible light beam identifiable by the target code scanning device. The target code scanning device may be a device used to scan the resource transfer code and perform resource transfer operations based on the scanning results. Alternatively, the target code scanning device may scan the resource transfer code and pass the scanning results to the processing device connected to it. The processing The device can perform resource transfer operations based on the scan results. For example, the target code scanning device may be a code scanning gun, a mobile phone, and other devices.

Through the resource transfer processing method 200A, the software and hardware of the existing equipment (i.e., the target scanning device and/or associated processing equipment, etc.) can be modified without changing the existing equipment, and there is no need to connect the existing equipment to the equipment executing this solution. Under the premise, the process of resource transfer is realized by analyzing characteristic images. This helps reduce additional costs caused by modifications or wiring, and also helps avoid the impact of external interference on device connections, thereby helping the system maintain better stability.

In some embodiments, step 230 may include: using a visible light beam to project the resource transfer code on the target surface, so that the resource transfer code is presented on the target surface through a difference in light intensity, wherein the target surface is located within the scanning range of the target scanning device. Inside. Alternatively, the visible light beam may be a monochromatic light beam of red, green, blue, white or other colors, or may also include two or more color beams. For example, a red diode laser can be used to project the resource transfer code. Optionally, the resource transfer code can be projected on the target surface through various projection methods, such as LCD (Liquid Crystal Display, liquid crystal display) projection technology, CRT (Cathode Ray Tube, cathode ray tube) projection technology, DLP (Digital Light Processor) , digital light processing) projection technology, etc. For example, the target surface may be at least part of the surface of the target object, or may also be the surface of other objects or a pre-placed plane. For example, the target surface may be the surface of the user's palm, the surface of the user's face, etc., or may be other object surfaces or specific planes placed near the device running the method 200 . Taking a one-dimensional barcode as an example, it can include a mark composed of a set of regularly arranged bars and spaces, and optionally, corresponding characters, where the arrangement of bars and spaces can express certain information. In such an example, strips and voids may be distinguished by differences in the intensity of light, e.g., projecting the strip portion with a stronger beam and projecting the void portion with a weaker beam, where projecting the void portion with a weaker beam may include not Project the empty part with a beam, that is, the beam intensity in the empty part is zero. Alternatively, the bar and empty portions can be projected in the opposite manner. As a result, the corresponding one-dimensional barcode can be rendered on the target plane. When the resource transfer code is projected on the target surface, the target code scanning device can scan the projected resource transfer code and implement the resource transfer operation based on the scan results, or pass the scan results to the relevant processing device to complete the resource transfer operation. Optionally, the target code scanning device can automatically detect whether a scannable resource transfer code appears within the scanning range and perform a scanning action, or the user can manually control the target code scanning device to scan the resource transfer code. By using visible light to project the resource transfer code and presenting the resource transfer code with light intensity differences on the target surface, the resource transfer code can be displayed conveniently and intuitively and avoid modifications to existing code scanning equipment. By rendering the resource transfer code directly on the surface of the target object, the layout of additional surfaces can be avoided, further helping to reduce costs and reduce overall system complexity.

In some embodiments, different colored beams may be used to project resource transfer codes based on the location of the target surface. Specifically, when the distance between the target surface and the light source used to project the visible light beam is within a preset range, the visible light beam of the first color can be used to project the resource transfer code on the target surface; when the distance between the target surface and the light source When the distance is not within the preset range, a second color visible light beam can be used to project the resource transfer code on the target surface. For example, when the target surface is the surface of the user's palm, if the distance between the user's palm and the light source is within a preset range, a green visible light beam can be used to project the resource transfer code on the palm surface; if the distance between the user's palm and the light source is When the distance between the two palms is not within the preset range, visible light beams of other colors (such as red, yellow, etc.) can be used to project the resource transfer code on the palm surface. As a result, the user can be intuitively reminded whether the position of the palm is appropriate, whether it is too far or too close, and whether the user needs to move the palm further closer or further away from the device to achieve a better projection effect, thereby ensuring that the resource transfer process can Implement smoothly and safely. It should be understood that the above-mentioned green, red, yellow, etc. are only examples, and the present disclosure does not limit the specific color of the visible light beam. In addition, for example, assuming that the preset range is [m, n], where m and n are real numbers greater than zero, then when the distance between the palm and the light source is in the range of m meters or more and n meters or less, you can The resource transfer code is projected with a visible light beam of the first color; when the distance between the palm and the light source is less than m meters or greater than n meters, the resource transfer code can be projected with a visible light beam of the second color; or, when the distance between the palm and the light source is less than m When the distance between the palm and the light source is greater than n meters, the resource transfer code can be projected with a visible light beam of the third color; and so on. Alternatively, the distance between a target surface such as a palm and the light source may be measured with the aid of visible light or invisible light, or the distance may be measured with the aid of a camera, or the distance may be measured in other ways.

In some embodiments, step 220 may include: obtaining resource transfer verification information associated with the target resource account based on the characteristic image, wherein the resource transfer verification information includes verification information for performing a resource transfer operation for the target resource account; Based on the resource transfer verification information, a resource transfer code is generated. For example, the resource transfer verification information may include information related to the target resource account, such as the identification of the target resource account, the identity of the attributed user, verification information preset by the user, etc., or may include randomly generated information associated with the target resource account. string, etc. For example, based on the resource transfer verification information, it can be converted into a corresponding resource transfer code according to preset rules. The preset rule may be commonly known by the device executing method 200 and the target scanning device (or the processing device associated with the target scanning device). That is, after the target scanning device or the associated processing device obtains the resource transfer code, , the resource transfer code can be converted into corresponding resource transfer verification information according to the preset rules, and then the resource transfer process can be implemented based on the resource transfer verification information. Optionally, the step of obtaining resource transfer verification information associated with the target resource account based on the characteristic image may be implemented locally or with the aid of an external device. In the above embodiment, by obtaining the resource transfer verification information and locally generating the resource transfer code, the overhead of data communication can be reduced, and the system design in related technologies can be more conveniently compatible.

Exemplarily, the resource transfer verification information associated with the target resource account can be obtained based on the characteristic image in the following manner: sending the characteristic image to the verification device and receiving the resource transfer verification information from the verification device. In such embodiments, the resource transfer verification information may be generated by the following process: extracting feature information from the feature image, determining a matching target resource account based on the feature information, and generating resource transfer verification information based on the determined target resource account. The verification device may, for example, be a device independent of the device executing the method 200. For example, the verification device may be deployed as the server 140 shown in FIG. 1 . For example, the characteristic image may be sent to the verification device via a wired or wireless network, and the verification device may extract characteristic information from the characteristic image, determine a matching target resource account based on the characteristic information, and generate a resource transfer verification based on the determined target resource account. information and feed back the generated resource verification information via a wired or wireless network. For example, the verification device can use a machine learning model to extract feature information from the feature image, such as feature information expressed in the form of feature vectors, strings, etc., and then compare the extracted feature information with the feature information stored in the database. , find the most matching feature information, and the resource account associated with the most matching feature information can be determined as the target resource account. When comparing the extracted feature information with the feature information stored in the database, the matching can be measured by the similarity of the feature information. For example, the similarity between the extracted feature information and multiple candidate feature information can be calculated. degree, such as similarity measured by distance, etc., the candidate feature information with the highest similarity can be regarded as the most matching feature information. By using a separate verification device to implement the step of obtaining the resource transfer verification information, it is helpful to simplify the structure of the computing device running the method 200, reduce its storage and processing capacity requirements, and facilitate unified management of the resource transfer verification information and resource accounts.

In some embodiments, step 220 may include sending the characteristic image to the verification device and receiving a resource transfer code from the verification device. In such embodiments, the resource transfer code may be generated by the following process: extracting feature information from the feature image, determining a matching target resource account based on the feature information, generating resource transfer verification information based on the determined target resource account, and based on the resource The transfer verification information generates a resource transfer code. Different from the previous embodiments, here, the resource transfer code can be received directly from the verification device, that is, the step of generating the resource transfer code based on the resource transfer verification information can be completed by the verification device. This helps further simplify the structure and processing logic of the computing device running method 200.

In some embodiments, step 210 may include: emitting coded light to the target object; receiving coded light reflected by the target object; and obtaining a characteristic image of the target object based on the reflected coded light, where the characteristic image includes at least Position and depth information of some points. For example, an emitter of invisible laser with a specific wavelength can be used as the light source that emits coded light, or a visible light source can also be used as the light source that emits coded light. Encoded light can carry encoded information (such as encoding patterns). When the encoded light is projected on the surface of the target object, due to the unevenness of the surface of the target object, the encoded information in the encoded light reflected by the surface will be distorted. After receiving the encoded light reflected by the surface of the target object, the distortion in the encoded information can be analyzed through a preset algorithm, and then the position and depth information of each point on the surface of the target object can be obtained. With the help of coded light, characteristic images of target objects can be obtained conveniently and accurately, thus helping to ensure the accuracy and safety of the resource transfer process. In addition, optionally, time of flight (ToF, Time of Flight), binocular stereo vision (Binocular Stereo Vision) and other methods can also be used to obtain the characteristic image of the target object containing depth information.

In some embodiments, the characteristic image of the target object can be obtained through the following steps: obtaining at least one image of the target object; filtering at least one image according to preset dimensions to obtain the characteristic image. The preset dimensions include the following: At least one of: the size of the target object, the angle of the target object, the contrast of the image, the brightness of the image, and the sharpness of the image. For example, at least one image of the target object may be acquired through a camera. For example, streaming media data (such as video data) of the target object may be acquired, where the streaming media data may include multiple images of the target object. When screening at least one image, for example, the same or different weights can be set for different preset dimensions according to requirements or experience, thereby selecting the image most suitable for feature extraction as the feature image. By acquiring at least one image and filtering the acquired images to obtain feature images, the quality of the acquired feature images can be improved, thereby helping to ensure the accuracy and security of resource transfer processing.

Schematically, FIG. 2B shows an example flowchart of a resource transfer processing method 200B according to some embodiments of the present disclosure. Similarly, the image processing method 200B may be applied to the scene 100 shown in FIG. 1 , for example, may be deployed on the computing device 110, the server 140, or a combination of both in the form of an application. As shown in the figure, in addition to the above steps 210 to 230, the resource transfer processing method 200B may include optional step 240, as detailed below.

In step 240, in response to receiving a message containing a resource transfer result, the resource transfer result may be presented, wherein the resource transfer result may include at least one of the following: information indicating successful resource transfer, information indicating failure of resource transfer , information indicating the amount of resource transfer, information indicating the transfer of resources out of the account, information indicating the transfer of resources into the account. Exemplarily, after the target scanning device scans the resource transfer code and completes the resource transfer operation (or after completing the resource transfer operation with the help of an associated processing device), the verification device can obtain the resource transfer result, and can provide the execution The device of method 200 sends a message containing the resource transfer result. After receiving the message, the device executing method 200 can present the resource transfer result through a display, voice broadcast, projection, etc. For example, a resource transfer result page may be presented to display the resource transfer result. By presenting the resource transfer results, users can be informed in a timely manner of whether the resource transfer is successful, the resource transfer amount, and/or the transfer-in account and transfer-out account involved in this resource transfer, which helps to improve the human-computer interaction experience and is helpful. Helps ensure the security of resource transfer.

To facilitate understanding, schematically, FIG. 3 shows an example interaction flow chart of a resource transfer processing method 300 according to some embodiments of the present disclosure. As shown in the figure, the resource transfer processing device can be used to execute the resource transfer processing methods 200A and 200B described in various embodiments above. The verification device can process the characteristic image and generate corresponding resource transfer verification information or resource transfer code ( As described above, the verification device is not necessary, and its function can also be performed by the resource transfer processing device).

To further facilitate understanding, taking the palm payment scenario as an example, FIG. 4 schematically shows an example architecture 400 of a payment system according to some embodiments of the present disclosure.

As shown in Figure 4, the user's palm (as the target object) can face the palm-swiping payment device, so that the palm-swiping payment device can perform palm recognition on the user's palm. Optionally, during the recognition process, the user's palm can remain parallel to the palm-swiping payment device. Payment device screen. After detecting the user's palm, the Palm Payment device can take an image containing the user's palm and send the image to the Palm Payment back-end service system to obtain the payment code. The palm payment back-end service system can process the image containing the user's palm, identify the user's identity, obtain the user's resource account information, and generate a payment code associated with the user's resource account information. The payment code can be fed back to the payment device. For example, when the payment code is, for example, a digital code, the palm payment device can convert it into a one-dimensional payment code and emit a laser to project the one-dimensional payment code onto the user's palm. Scanning devices (such as code scanners) can be placed in specific locations and continuously identify one-dimensional payment codes in a fixed area. Alternatively, the scanning devices can be handheld devices that can move within a certain range based on the operations of the cashier. to identify one-dimensional payment codes. When a projected one-dimensional payment code appears on the user's palm, the scanning device can recognize the one-dimensional payment code, and can subsequently transfer the recognized payment code to the merchant's POS (Point of Sale) system, for example Use a regular HID (Human Interface Device) communication connection to transfer the payment code to the merchant POS system. After receiving the payment code, the merchant's POS system can use the system software to transfer the payment code to the merchant's thickness service system to complete the payment operation. At this point, the swipe payment process can be completed. It can be seen that by using a laser to project a one-dimensional payment code on the user's palm, the palm payment function can be added without making changes to the software and hardware of the scanning equipment, merchant POS system and merchant back-end service system, while avoiding the need to pass through Disadvantages such as increased cost and instability caused by line or Bluetooth signal connection.

As shown in Figure 5, the payment system 500 may include a swipe payment device, a merchant POS system, and back-end services.

Specifically, the palm-swiping payment device may include a 3D camera and be deployed with a palm-swiping payment application. The 3D camera can be any form of camera, such as structured light camera, light time-of-flight camera, binocular stereo vision camera, etc. Here, taking a structured light 3D camera as an example, it can include an infrared module that can emit invisible light of a specific wavelength. As described in the previous embodiments, the invisible light can be a code that carries coded information. Light, when the coded light is projected on the palm surface, can be reflected by the palm surface. The 3D camera can receive the reflected coded light and calculate the distortion of the coded pattern in the reflected light through a certain algorithm, thereby obtaining the palm and palm surface. location and depth information. In addition, the 3D camera module can also be equipped with a visible light source (not shown). This visible light source will only be enabled when projecting a payment code. The visible light it emits does not carry encoded information and is only used to project payment on the surface of the user's palm. code. For example, the visible light source may be a red diode laser or other types of light sources. The palm payment application can include a palm recognition module, a one-dimensional code generation module and a result page module. The palm recognition module may include a biopsy sub-module and a preference sub-module. The biopsy sub-module can call the 3D camera to perform the living body detection function and collect the streaming data of the user's palm when the presence of the user's palm is detected. After obtaining the streaming media, the optimization sub-module can optimize the images in the streaming media data to select the optimal palm picture. The optimization criteria may include coefficient indicators such as palm size, angle, image contrast, image brightness, and image sharpness. The optimal palm image can then be sent to a backend service for palm recognition. Backend services may include palm recognition services, basic payment services, basic account services, and other optional services. After receiving the palm image data from the palm payment device, the palm recognition service can extract features from the palm image and compare the features with the features in the database to find the feature data with the highest score to match to the closest palm data. After the matching is completed, the user's resource account can be obtained through the basic account service, and the corresponding payment code can be generated with the help of the basic payment service. The payment code can be passed to the brush payment device and obtained and processed by the brush payment application. For example, the payment code can be a digital code generated according to preset rules. After obtaining the digital payment code, the one-dimensional code generation module in the brush payment application can convert the digital payment code into a one-dimensional code, and use The visible light source in the 3D camera module projects the one-dimensional code onto the surface of the user's palm. Or the payment code returned by the back-end service can be a one-dimensional code. In this case, the palm payment application can directly project the one-dimensional code onto the surface of the user's palm with the help of the visible light source in the 3D camera module. The code scanner gun in the merchant's POS system can scan and identify the one-dimensional code projected onto the surface of the user's palm in automatic or manual mode, and transfer the recognized payment code to the POS machine through the HID connection, and the POS machine can transfer the payment code Go to the merchant payment service system to complete the payment operation. After the payment operation is completed, the basic payment service of the back-end service can feed back a message containing the payment result to the Shuazhang payment application in the Shuazhang payment device, and the result page module in the Shuazhang payment application can display the received payment results. In this way, through the payment system 500, the palm payment process described above can be completed.
