detailed description

The video shooting method based on ambient light detection provided in this application can be applied in the application environment as shown in FIG. 1, where the client communicates with the server through the network. Among them, the client includes, but is not limited to, various computers, notebook computers, smart phones, tablet computers, and smart terminals. The server can be implemented as an independent server or a server cluster composed of multiple servers.

In one embodiment, as shown in FIG. 2, a video shooting method based on ambient light detection is provided. The method is applied to the server in FIG. 1 as an example for description, including the following steps:

S10: Receive an initial command including the acquisition frequency, start condition, and end condition.

In this embodiment, the collection frequency refers to the frequency at which the current value is collected between the start condition and the end condition; and optionally, the start condition is used to trigger a start collection command, which may be server detection When the user is in the field of view of the camera module, it can also be a preset button that is set on the client and bound to the start collection command when a trigger (triggered by voice or gesture, etc.) is detected; the end condition is used to trigger the end The acquisition command may be the server detecting that the light detection duration reaches the preset duration threshold, or it may be the detection that triggers the preset button that is set on the client and is bound to the end acquisition command.

S20: When the start acquisition command is triggered according to the start condition, the current value of the camera module set in the preset environment is acquired according to the acquisition frequency, and the acquisition is stopped and recorded until the end acquisition command is triggered according to the end condition All the current values collected between the first time point when the start collection command is triggered and the second time point when the end collection command is triggered, and a detection signal is generated according to all the current values.

Wherein, the camera module includes a photosensitive element, a single camera or a freely switchable camera group; and the camera module may be a camera module that is communicatively connected with the client and installed on the client, or it may be The camera module directly communicates with the server.

Preferably, when receiving the initial command including the acquisition frequency, start condition, and end condition sent from the client, first respond and execute the start acquisition command triggered by the start condition, start data acquisition, store and record the execution of the start acquisition command The system time is used as the first time point and the current value of the camera module set in the preset environment is acquired according to the acquisition frequency; then responds and executes the end acquisition command triggered according to the end condition, stops data acquisition, stores and records the execution end acquisition command The system time of the hour is used as the second time point, and a detection signal is generated according to all the current values stored during the first time point and the second time point during the light detection time period. Preferably, the detection signal refers to a pseudo waveform signal whose time and amplitude are coordinate axes.

S30. Waiting for and receiving a processing instruction including the detection signal, and calling a preset signal processing model to convert the detection signal into a light intensity value of the preset environment.

Wherein, the signal processing model may be preset on the server. Preferably, the signal processing model can be written in C/C++, which can significantly improve the computing speed of the server and has a wider applicability. For example, it is suitable for mobile terminals and tablet computers with various operating systems.

Preferably, the waiting threshold is set according to the light detection time and the signal generation time of the detection signal generated by the signal generation model, and the execution time of the first time point when the start acquisition command is executed and the current system time is recorded in real time, when the execution time reaches When waiting for the threshold, the server automatically generates a processing instruction containing the detection signal. At this time, after calling the preset signal processing model to normalize the acquired detection signal, signal conversion, signal analysis, and brightness value calculation, Obtain the brightness corresponding to the detection signal, that is, the light intensity value of the preset environment. That is, the signal processing model is called, and the detection signal is first converted into aperiodic light waves using a preset mapping relationship, and the aperiodic light waves are split by a preset transformation formula (preferably fast Fourier transform). Divide into multiple superimposed waves containing basic parameters, where the basic parameters include phase, amplitude and frequency; then use the basic parameters of each superimposed wave to determine the wavelength of each superimposed wave and the corresponding color wave, and use the preset color gamut Figure obtains the R value, G value and B value of each color wave; finally obtains the sub-brightness value of each color wave using a preset brightness model, and obtains the non-periodic light wave based on the sub-brightness value of each color wave The brightness value of is also the light intensity value of the preset environment.

S40: Input the light intensity value into a preset brightness level model, and receive the light intensity level output by the brightness level model.

Preferably, the brightness level model is based on a deep learning model, and the brightness level model is obtained by training using training samples in a database. The training process of the brightness level model includes: obtaining training samples, the training samples containing historical light intensity values and the standard intensity levels corresponding to the historical light intensity values (set according to expert rules); The training sample is trained, and the overall error degree between the light intensity level output after the training and the corresponding historical light intensity value in the training sample is obtained; whether the overall error degree is greater than a preset error threshold is detected, When the overall error is less than or equal to the error threshold, it is prompted that the model training is completed; otherwise, the initial function of the brightness level model is adjusted to a corrected function, and the brightness level model that includes the corrected function is used to The training sample is retrained, and the overall error degree between the light intensity level obtained after the retraining and the corresponding historical light intensity value in the training sample is obtained, and it is determined whether the overall error degree is greater than the error threshold , And so on, until the overall error degree is less than or equal to the error threshold, indicating that the model training is completed. The initial function is composed of level coefficients and initial parameters (the maximum set brightness value).

It is understandable that by analyzing the light intensity value based on the brightness level model, a highly accurate light intensity level can be obtained, which is conducive to adjusting and determining the ambient light intensity during video shooting in the subsequent steps, thereby improving the The quality of the video collected by the camera module increases the pass rate during video review; at the same time, the light intensity level obtained by using the brightness level model has no level limit and is more accurate.

S50: Input the light intensity level into a preset matcher, and receive a matching result output by the matcher.

Wherein, the matching result includes a first result (e.g., "1") for characterizing level matching, a second result (e.g., "+0") and a third result (e.g., " -0").

Optionally, input the light intensity level into a preset matcher, and first detect whether the light intensity level matches a preset level range, and when the light intensity level matches the preset level range, the The matcher outputs "1", and when the light intensity level does not match the preset level range, the level mismatch is further determined, that is, the positive and negative value of "0" as the result of detecting level mismatch , When the light intensity level is higher than the maximum level of the level range, the matcher outputs "+0"; and when the light intensity level is lower than the minimum level of the level range, the matcher outputs "-0" ". It is understandable that obtaining the matching result corresponding to the light intensity level based on the matcher is beneficial to improving the matching efficiency.

S60: Acquire and execute a corresponding control operation according to the matching result, and command the camera module to shoot a dynamic video according to the control operation.

In this embodiment, one matching result corresponds to one or more control operations. Optionally, when the matching result is the first result (e.g., "1"), the camera module is directly asked to shoot video to obtain the user's dynamic video; and when the matching result is the second result (e.g., "+0") ), in order to avoid the impact of high light intensity on video shooting, after adopting preset adjustment measures, make the camera module perform video shooting to obtain the dynamic video of the user, for example, by using a hood, Or switch to a high-quality coated camera, or adjust the video shooting angle and other adjustment measures to avoid problems such as overexposure and glare during video shooting; and when the matching result is the third result (for example, "-0"), in order to avoid light intensity Weak impact on video shooting. After adjusting the light intensity of the preset environment through the preset lighting module, check the light intensity level of the adjusted preset environment again, and determine the light intensity level of the adjusted preset environment After matching with the preset level range, that is, the step S10 to the step S50 are executed again, until it is detected that the matching result is the first result (for example, "1"), the camera module is made to perform video shooting to obtain Dynamic videos of users. Further, user information, device information, shooting time information, etc. are stored in association with the dynamic video.

In summary, this embodiment first receives the initial instruction, and acquires all currents collected at the acquisition frequency between the first time point and the second time point according to the start acquisition command triggered by the start condition and the end acquisition command triggered by the end condition. And generate detection signals based on all current values; then call the signal processing model according to the processing instructions to convert the detection signals into light intensity values, and use the brightness level model to obtain the light intensity level corresponding to the light intensity value; finally, use the matcher to The light intensity level is matched and judged to obtain the matching result, and different video shooting methods are realized according to the control operation corresponding to the matching result. In the ambient light detection process in this embodiment, the accuracy and detection speed during light detection are improved, the server load is reduced, and the running speed of the server is significantly improved. Furthermore, after the ambient light detection, corresponding control operations are executed according to different matching results, and different video shooting schemes are realized, which can improve the video shooting effect and quality, reduce the workload of video review, and increase the qualification rate of video review. The purpose of efficiency.

In an embodiment, as shown in FIG. 4, in the video shooting method based on ambient light detection, the camera module includes a photosensitive element; the step S20 specifically includes the following steps:

S201: Respond to and execute a collection start command triggered according to the start condition, store the current value output by the photosensitive element acquired at the first time point when the collection start command is executed, and obtained according to the collection frequency.

Specifically, the initial instruction may also include a positioning identifier. At this time, respond to and execute the start collection command triggered according to the start condition to start data collection. The start of data collection will be executed at the first time point when the start collection command is executed. The current value output by the photosensitive element obtained according to the acquisition frequency and the positioning identifier are associated and stored in the database. In the subsequent steps, the data associated with the positioning identifier in the database can be retrieved according to the positioning identifier to improve the query speed.

Preferably, the camera module includes photosensitive elements such as photoresistors and light pipes based on the photoelectric effect, and changes in the resistance value of the photosensitive elements caused by changes in the light intensity of the preset environment, and then records the current value changes caused by the changes in resistance value in real time . The real-time recording of the current value change caused by the change of the resistance value may be collected and recorded by the preset data acquisition device and the current value output by the photosensitive element, or may be obtained according to the obtained resistance value of the photosensitive element and a preset data conversion model Current value. Preferably, the data conversion relationship is:

Among them, I is the current value; U is the voltage value; R is the resistance value. It is understandable that the voltage value has been preset in the data conversion model, for example, the voltage value is 2.5.

S202. Respond to and execute the end collection command triggered according to the end condition, and store all the light detection durations that have elapsed between the first time point and the second time point when the end collection command is executed. Current value.

Specifically, respond to and execute the end collection command triggered according to the end condition, stop data collection, and change the experience experienced at the second time point, the first time point, and the second time point when the end collection command is executed. The current value and the location identifier of the segment of light detection time are stored in a database in association.

S203: Generate a detection signal according to all the current values and a preset signal generation model.

Specifically, according to the real-time acquisition time point and the current value of each acquisition time point obtained during the detection period of the light, a preset signal generation model is used to generate a pseudo waveform with the time point as the abscissa and the current value as the vertical coordinate. And record the pseudo waveform as a detection signal.

In summary, this embodiment stores the current value output by the photosensitive element collected between the first time point when the start collection command is triggered and the second time point when the end collection command is triggered, and generates detection information according to the current value, and detects The data included in the signal is richer, which helps to improve the accuracy of light detection.

In an embodiment, as shown in FIG. 5, the step S30 specifically includes the following steps:

S301: Input the detection signal into the signal processing model, and enable the signal processing model to normalize the detection signal to obtain aperiodic light waves. That is, the detection signal is reduced by a preset ratio using a preset mapping relationship to obtain aperiodic light waves.

S302: After enabling the signal processing model to perform signal transformation on the non-periodic light wave, obtain each superimposed wave and basic parameters of each superimposed wave. Preferably, a fast Fourier transform is used to split the non-periodic light waves into superimposed waves of visible light waves (each superimposed wave is a periodic light wave), and the phase, frequency direction, and amplitude of each superimposed wave are different.

S303: After the signal processing model performs signal analysis on each of the superimposed waves according to the basic parameters of each of the superimposed waves, the R value, G value, and B value corresponding to each superimposed wave are obtained. That is, the wavelength of each superimposed wave is obtained according to the frequency of each superimposed wave and the preset wavelength formula, thereby mapping which color wave each superimposed wave belongs to, and further, using the preset color gamut map to map the corresponding color wave R value, G value and B value. It is understandable that a superimposed wave corresponds to a color wave. For example, by using a preset mapping relationship table (used to store the mapping relationship between wavelengths and color waves), it can be learned that the superimposed wave with a wavelength of 590 to 600 nm is an orange wave, and Using the preset color gamut map, it can be known that the R value of the orange wave is 22, the G value is 107, and the B value is 201.

S304. Allow the signal processing model to calculate the partial brightness value of each superimposed wave according to the R value, G value, and B value corresponding to each superimposed wave, and obtain the partial brightness value of each superimposed wave based on the partial brightness value of each superimposed wave. After the brightness value of the aperiodic light wave, the brightness value of the aperiodic light wave output by the signal processing model is recorded as the light intensity value of the preset environment. That is, the brightness model included in the signal processing model and the R value, G value, and B value of each color wave are used to obtain the partial brightness value of each color wave, and the partial brightness value of each color wave is superimposed and accumulated to obtain the The brightness value of the non-periodic light wave (that is, the mixed wave), and then the brightness value of the non-periodic light wave is recorded as the light intensity value of the preset environment.

Preferably, in an embodiment, in the video shooting method based on ambient light detection, the signal processing model includes a brightness model for calculating the partial brightness value of each superimposed wave, and the brightness model is:

y=k1*R+k2*G+k3*B

Where y is the sub-brightness value corresponding to the superimposed wave; R is the R value corresponding to the superimposed wave; G is the G value corresponding to the superimposed wave; B is the B value corresponding to the superimposed wave; k1 is R The first coefficient corresponding to the value; k2 is the second coefficient corresponding to the G value; k3 is the third coefficient corresponding to the B value; and the k1, k2, and k3 are constant terms. Preferably, k1 is 0.299, k2 is 0.587, and k3 is 0.114. At this time, the partial brightness value output by the brightness model is the most accurate.

To sum up, in the process of detecting ambient light in this embodiment, the signal processing model is called to normalize the detected signal, signal conversion, signal analysis, and brightness value calculation to obtain the light intensity value of the preset environment. The signal processing The process is simpler and the platform has a wider applicability, which reduces the server load and significantly improves the server operating speed; at the same time, it improves the accuracy and efficiency of ambient light detection.

In one embodiment, the matching result includes a first result for characterizing level matching, and a second result and a third result for characterizing level mismatch; the step S60 specifically includes the following steps:

When the matching result is the first result, a first control operation corresponding to the first result is acquired and executed, and the first control operation is to instruct the camera module to shoot a video and acquire a dynamic video. That is, when the matching result is the first result (for example, "1"), the server sends a first control operation to the camera module, and starts the camera of the camera module according to the first control operation. Video shooting to obtain dynamic video. Wherein, the camera module may be a camera module that is communicatively connected with the client and installed on the client, or may be a camera module that is directly communicatively connected with the server.

When the matching result is the second result, a second control operation corresponding to the second result is acquired and executed, and the second control operation refers to a light module set in the preset environment After adjusting the brightness of the preset environment, the camera module is made to shoot a video to obtain a dynamic video. That is, when the matching result is the second result (for example, "+0"), the server sends a second control operation to the camera module to obtain the light intensity of the preset environment from the database Level-matched compensation parameters (including the number of LEDs turned on in the lighting module, the brightness of each LED turned on, etc.), the lighting module is controlled to turn on the compensation parameters, and then the light intensity level of the preset environment After the adjustment, the camera of the camera module is started for video shooting to obtain dynamic video.

When the matching result is the third result, a third control operation corresponding to the third result is acquired and executed, and the third control operation refers to switching the camera of the camera module, and switching The latter camera shoots videos to obtain dynamic videos; the camera module includes multiple cameras that can be switched freely, and the multiple cameras can be set according to requirements, for example, two or more cameras. That is, when the matching result is the third result (for example, "-0"), the server sends a third control operation to the camera module, and according to the third control operation, the camera module Switch the camera of the camera to a camera suitable for a low-light environment, and start the switched camera for video shooting to obtain dynamic video. It is understandable that different light intensity environments are suitable for cameras with different parameters, and the light intensity, camera parameters, and the relationship between the light intensity and the camera have been pre-stored in the database. Therefore, you can obtain high values by switching cameras. Quality dynamic video. Optionally, when the server is applied to an intelligent dual recording system, video audit and user identity verification can be performed based on the dynamic video.

In summary, after detecting the ambient light, this embodiment executes corresponding control instructions according to different matching results to realize different video shooting methods (including but not limited to time-lapse shooting, light compensation shooting, and switching camera shooting). This improves the quality and effect of video shooting, reduces the workload during video review and increases the pass rate, thereby improving the efficiency of video review.

In an embodiment, when the light intensity level corresponding to the light intensity value is not obtained, the light intensity value is directly used for numerical detection to obtain the detection result, and the instruction operation is implemented based on the detection result; the step S30 further includes The following steps:

It is detected whether the light intensity value is within a preset numerical range; the preset numerical range includes a first threshold and a second threshold, and the first threshold is less than the second threshold. When the light intensity value is within the preset value range, the preset first instruction is called and executed, and the first instruction refers to controlling the camera module to shoot video and obtain dynamic video. When the light intensity value is less than the first threshold value, a preset second instruction is called and executed. The second instruction refers to controlling the preset lighting module to adjust the brightness of the preset environment and then controlling The camera module shoots video and obtains dynamic video.

When the light intensity value is greater than the second threshold, a preset third instruction is called and executed. The third instruction refers to controlling the camera module to delay shooting, and detecting the light of the preset environment again Intensity value, until the light intensity value detected again is within the preset value range, the camera module is controlled to shoot a video to obtain a dynamic video. It is understandable that the preset value range is the optimal range of light intensity values suitable for video shooting obtained after many experiments. At this time, the quality and effect of the dynamic video obtained by shooting under the preset value range are optimal.

In summary, after detecting the ambient light, this embodiment directly uses the light intensity value to perform numerical detection to obtain the detection result, and implements corresponding command control based on different detection results, which is beneficial to reduce the video shooting time and improve the user experience ; At the same time, it can achieve the purpose of improving the quality and effect of video shooting, thereby increasing the pass rate and efficiency of video review.
