Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a printing control method based on a scanning gun according to an embodiment of the present invention, where this embodiment is applicable to a situation of performing printing control based on a scanning gun, and specifically includes the following steps:
and step 110, acquiring the bar code image data scanned by the scanning gun.
In this embodiment, the barcode image data may be used to characterize a barcode image generated by the scanning gun based on the scanned barcode information, for example, may be a barcode image photo generated by the scanning gun based on the scanned information.
And 120, generating printing adjustment information according to the definition information of the bar code image data.
Specifically, after the barcode image data is acquired, the barcode image data may be processed through a preset algorithm to determine the definition information of the barcode image data. The definition information can be used for representing the definition of the barcode image, such as the definition value of the barcode image. Subsequently, the definition information can be compared with reference definition information preset in the scanning gun, and result information obtained by comparison can be used as definition difference information so as to perform analysis processing by adopting the definition difference information and generate corresponding printing adjustment information. The reference definition information may include various parameter thresholds for definition determination, such as a grayscale parameter threshold, a brightness parameter threshold, and the like, which are set in the scanning gun in advance according to the barcode printing definition requirement, and the embodiment of the present invention is not particularly limited to this; the definition difference information can represent the difference degree between the definition of the barcode image obtained by the current scanning of the scanning gun and the definition threshold of the preset barcode image, and can be specifically used for processing the barcode image data obtained by the current scanning so as to generate the restored image data corresponding to the barcode image data.
In an optional implementation manner, the generating of the printing adjustment information according to the definition information of the barcode image data in this embodiment may specifically include: determining definition information of the bar code image data; comparing the definition information of the bar code image data with preset reference definition information to obtain definition difference information; analyzing and processing the information based on the definition difference to generate restored image data corresponding to the bar code image data; and generating printing adjustment information according to the restored image data and preset printing parameter information. It should be noted that the preset printing parameter information may include various printing parameters set in the scanning gun in advance, such as a horizontal resolution, a vertical resolution, a coverage rate, and the like set for the preset reference definition information, which is not limited in this embodiment in particular. The coverage ratio can be used to control the percentage of the area covered by the printing ink relative to the whole printing paper area during printing, such as the coverage ratio of a printer.
And step 130, determining printing parameter information according to the printing adjustment information, and sending the printing parameter information to a printer, wherein the printer is used for printing according to the printing parameter information.
In the embodiment of the invention, whether the printing parameters of the printer connected with the scanning gun currently need to be adjusted or not can be determined based on the generated printing adjustment information. If the printing parameters of the printer need to be adjusted, the printing parameters currently set by the printer can be adjusted according to the printing adjustment information, so that the information generated after adjustment is used as the printing parameter information and is sent to the printer, the printer is triggered to print the barcode image data scanned by the scanning gun according to the printing parameter information, and the printer can be ensured to print clear barcode information.
To sum up, after acquiring the barcode image data scanned by the scanning gun, the embodiment of the present invention may generate the printing adjustment information according to the definition information of the barcode image data, so as to determine the printing parameter information according to the printing adjustment information, and then may send the printing parameter information to the printer, so that the printer may print the barcode image data scanned by the scanning gun according to the printing parameter information, thereby avoiding the problem that the barcode printing is not clear due to the printer printing according to the fixedly set printing parameters, i.e., solving the problem of blurred barcode printing in the prior art when the barcode image data is printed based on the barcode information scanned by the scanning gun.
In a particular implementation, the scanning gun is typically provided with an image sensor, such as a Complementary Metal Oxide Semiconductor (CMOS) sensor, to scan barcode information through the image sensor to generate corresponding barcode image data. Therefore, in an optional embodiment of the present invention, the scan-based print control method implemented by the present invention may further include, before acquiring the barcode image data scanned by the scanning gun: and driving an image sensor of the scanning gun. Wherein, the above-mentioned bar code image data who obtains scanning rifle and scan can include: and acquiring scanning data generated by the image sensor to serve as the barcode image data.
Referring to fig. 2, a flowchart illustrating steps of a scan gun based printing control method according to an alternative embodiment of the present invention is shown, where the scan gun based printing control method may specifically include the following steps:
In specific implementation, when information on a barcode such as a barcode and a two-dimensional code needs to be printed, an image sensor of a scanning gun may be driven by sending an instruction or a signal, so as to trigger the image sensor to scan and generate corresponding scanning data, thereby implementing a scanning function of the scanning gun.
Specifically, the scan data generated by the image sensor may be used to generate an image photograph corresponding to a barcode scanned by the scanning gun. Therefore, in the embodiment of the invention, after the image sensor generates the scanning data, the scanning data can be acquired, and the acquired scanning data can be determined as the barcode image data, so as to generate the corresponding barcode image photo according to the barcode image data.
In this embodiment, operators of a preset algorithm, such as Sobel (Sobel) operator and Laplacian (Laplacian) operator, may be set in the scan gun in advance, so as to determine the definition of the barcode photo represented by the barcode image data through the operators of the preset algorithm.
Specifically, after the barcode image data is obtained, the barcode image information data may be calculated by using an operator of a preset algorithm, and a result obtained by the calculation may be determined as the definition information of the barcode image data. The sharpness information may be used to characterize the sharpness of the barcode image represented by the barcode image data, e.g., may be a sharpness value.
As an example of the present invention, the scan gun may determine the sharpness value of the currently acquired barcode image data through preset Sobel and Laplacian operators, and then perform step 240.
And 240, comparing the definition information of the barcode image data with preset reference definition information to obtain definition difference information.
In this embodiment, the parameter threshold included in the reference sharpness information may be used as a sharpness reference value, and may be specifically used to determine whether a barcode image represented by barcode image data currently scanned by the scanning gun needs to be restored, so as to restore the barcode image currently scanned by the scanning gun.
Specifically, the embodiment of the present invention may compare the definition information of the currently determined barcode image data with the preset reference definition information in the scanning gun, so as to determine the difference between the definition value of the barcode image currently scanned by the scanning gun and the preset definition reference value, and generate the corresponding definition difference information. The definition difference information may be used to represent a difference degree between the definition of the barcode image represented by the currently acquired barcode image data and the definition of the preset barcode image in the scanning gun, and specifically may include: sharpness difference value, standard deviation, variance, etc. The definition difference value may be a difference value between the definition of the barcode image represented by the barcode image data and the definition of the preset barcode image.
For example, the sharpness value of the barcode image represented by the code image data may be compared with a sharpness reference value set by the scanning gun to obtain a sharpness difference value, a standard deviation and a variance of the sharpness value of the barcode image and the sharpness reference value set by the scanning gun may be calculated, and then the sharpness difference value, the standard deviation and the variance may be determined as sharpness difference information, so as to perform step 250 according to the sharpness difference value, the standard deviation and the variance.
And 250, analyzing and processing based on the definition difference information to generate restored image data corresponding to the barcode image data.
Specifically, after the definition difference information is determined, the embodiment of the present invention may analyze and process the acquired barcode image data by using the definition difference information to restore a barcode image corresponding to the barcode image data, and generate corresponding restored image data. The restored image data may be used to characterize the restored barcode image.
For example, based on the definition difference value, the standard deviation, and the variance in the definition difference information, the scanning gun may apply a gaussian algorithm and a Log (Logarithms, Log) algorithm, analyze, calculate, and process the barcode image data using laplace convolution to restore the barcode image scanned by the scanning gun, and may generate restored image data corresponding to the barcode image data for the restored barcode image.
In this embodiment, the print parameter information may be set in the scan gun in advance, for example, print parameters such as the horizontal resolution, the vertical resolution, and the coverage rate may be set according to the reference sharpness information of the barcode image, so as to be used as standard print parameters during printing, thereby determining that a clear barcode is printed.
Specifically, after the scanning gun generates the restored image data, the scanning gun can search for a printing parameter matched with the definition of the barcode image in preset printing parameter information based on the definition of the barcode image represented by the restored image data, and then can use the searched matched printing parameter as printing adjustment information, so that the printing parameter information which is required to be set currently by the printer can be determined according to the printing adjustment information.
Specifically, after generating the print adjustment information corresponding to the currently acquired barcode image data, the embodiment of the present invention may compare the print adjustment information with the print setting information of the printer currently connected to the scanning gun, so as to determine whether the print parameters of the printer need to be adjusted. Therefore, in an optional embodiment, determining the printing parameter information according to the printing adjustment information may specifically include: acquiring printing setting information of a printer; and when the printing adjustment information is not matched with the printing setting information, adjusting the printing setting information by adopting the printing adjustment information, and taking the printing setting information generated after adjustment as the printing parameter information, wherein the printing parameter information comprises transverse resolution information and longitudinal resolution information. If the currently generated printing adjustment information matches the printing setting information, the current printing setting information of the printer may be directly used as the printing parameter information, and a printing instruction may be sent to the printer or step 280 may be executed to trigger the printer to print according to the currently set printing parameter information.
In the actual processing, the code scanning gun may be connected to the printer through a Universal Serial Bus (USB), a network, bluetooth, or other connection methods, and may communicate with the printer according to a transmission protocol corresponding to the connection method, such as transmitting data and instructions.
In an optional embodiment of the present invention, sending the printing parameter information to a printer may specifically include: determining a connection between the scanning gun and the printer, the connection including at least one of: a network connection mode, a Bluetooth connection mode and a universal serial bus connection mode; and sending the printing parameter information to a printer according to a transmission protocol corresponding to the connection mode.
For example, when the scan gun is connected to the printer via a bluetooth connection, the print parameter information may be sent to the printer according to a transmission protocol, namely a bluetooth communication protocol, corresponding to the bluetooth connection, so as to trigger the printer to print according to the print parameter information, thereby ensuring the definition of the barcode information printed by the printer.
For another example, when the scanning gun is connected to the printer via a network, that is, when the connection mode between the scanning gun and the printer is a network connection mode, the printing parameter information determined by the scanning gun may be sent to the printer according to a transmission protocol corresponding to the network connection mode, that is, a network transmission protocol, to trigger the printer to print the restored image data analyzed and processed by the scanning gun according to various printing parameters in the printing parameter information, thereby solving the problem of unclear printing when the printer prints the barcode information scanned by the scanning gun in the prior art, and improving the printing definition of the printer.
Similarly, when the scanning gun is connected with the printer through the USB, the printing parameter information can be sent to the printer according to a transmission protocol, namely a USB communication protocol, corresponding to the USB connection mode, so that the printer is triggered to print according to the printing parameter information, and the definition of the bar code information printed by the printer can be ensured.
Therefore, the embodiment of the invention obtains the bar code image data by driving the image sensor of the scanning gun, the definition information of the bar code image information can be compared with preset reference definition information to obtain definition difference information, then analysis processing can be carried out based on the definition difference information to generate restored image data corresponding to the bar code image data, generating printing adjustment information according to preset printing parameter information of the restored picture data, determining final printing parameter information based on the printing adjustment information, and sending the printing parameter information to a printer according to a transmission protocol corresponding to the connection mode between the scanning gun and the printer so that the printer can print according to the printing parameter information, and then the definition of the bar code information scanned by the printer in the process of printing the scanning gun can be ensured.
