Since a large number of electronic products in the market generally have a photographing function, a performance test of a camera also becomes an indispensable detection item for each type of electronic product, the camera detection requires an environment with constant and uniform color temperature and illumination, but the production line environment is relatively complex, the stability of a light source is challenged, and the requirement of a relatively stable light source device is high.

However, this method requires a lot of manpower and time for spot inspection, and during the operation of a lot of production lines, the production capacity is seriously delayed, and the accuracy of the brightness spot inspection is affected due to the shielding of personnel.

The method, the apparatus, the device and the computer readable storage medium for light source point detection provided in the embodiments of the present application are specifically described in the following embodiments, and first, the method for light source point detection in the embodiments of the present application is described.
The embodiment of the application provides a light source point inspection method, and referring to fig. 1, fig. 1 is a schematic flow diagram of the light source point inspection method provided in an embodiment of the application, the light source point inspection method can be applied to light source point inspection equipment and is used for performing light source point inspection on an optical box, the optical box comprises at least one group of light sources, and the optical box is used for performing performance inspection on a camera module to be inspected; as shown in fig. 1, the light source point inspection method provided by the present embodiment includes steps S10 to S50.
Step S10, acquiring a test image of the light box;
it should be noted that, the executing main body in this embodiment is a light source pointing device, the light source pointing device may be a Personal Computer (PC), the light box is a test environment for placing and detecting the performance of the camera module to be detected, for convenience of understanding, an application scene schematic diagram shown in fig. 2 may be referred to, in fig. 2, a left side device is the light box, one side of the light box is open, the material of the remaining five surfaces (corresponding to reference numeral 3) may be PMMA (polymethyl methacrylate), or may be a diffuser, each surface of which has a checkerboard-format test chart (corresponding to reference numeral 2), wherein the top and the other three sides of the light box are provided with light sources (corresponding to reference numeral 5), each light source is connected to a light source controller (corresponding to reference numeral 6) on the right side of the light box, the camera module to be detected (corresponding to reference numeral 4) may be placed at the bottom of the light box, the top of the light box is provided with an industrial camera (corresponding to reference numeral 1), and in this embodiment, the data processing device (corresponding to reference numeral 7) obtains a test image of the light box through the industrial camera module.
In some possible embodiments, a preset camera is arranged on the light box;
the step S10 may specifically include:
step S11, sending an image shooting instruction to the preset camera;
it can be understood that before the performance of the camera module to be tested needs to be tested, it needs to be ensured that the testing environment, i.e. the light source in the light box, is set correctly, and at this time, the data processing PC can send an image shooting instruction to the preset industrial camera arranged on the light box.
And S12, receiving a test image of the light box shot by the preset camera based on the image shooting instruction.
It will be appreciated that the industrial camera, upon receiving the image capture command, will capture the light box and send the captured image to the data processing PC.
Step S20, carrying out data processing on the test image to obtain a gray picture;
in this embodiment, after receiving the light box picture, the data processing PC invokes a gray scale algorithm to perform gray scale processing on the light box picture to obtain a corresponding gray scale picture.
Illustratively, the grayscale algorithm may be Gray = (Red + Green + Blue)/3.
S30, generating a test result according to the gray level picture;
it should be noted that after the grayscale image is obtained, the data processing PC selects some point locations in the grayscale image and extracts the grayscale values of the point locations, and the grayscale values of the point locations are compared with the upper and lower limits of the preset grayscale value specification, so as to obtain the test result.
In some possible embodiments, the step S30 includes:
s31, selecting a plurality of preset point positions in the gray-scale picture;
in this embodiment, some point locations having a relatively large correlation with the output parameter of the light source may be selected as standard points for determining whether the output parameter of the light source meets the detection requirement, so that, after the grayscale picture is obtained based on the test image of the light box, whether the output parameter of each light source in the light box meets the detection requirement may be determined by selecting these preset point locations in the grayscale picture.
Step S32, obtaining the gray value of each preset point;
step S33, comparing the gray value of each preset point with a preset specification range to generate a test result.
In this embodiment, after a plurality of preset point locations are captured on a grayscale image, the grayscale value of each preset point location is read, and after the grayscale value of each preset point location is read, the grayscale value of each preset point location is compared with a preset specification range, so as to determine whether the grayscale value of each preset point location is within the preset specification range, where the preset specification range includes a lower specification limit and an upper specification limit, for example, the lower specification limit is set to 45, the upper specification limit is set to 50, and if the grayscale value of a preset point location is between 45 and 50, the preset point location is considered to be within the preset specification range.
Exemplarily, the test result generation rule in this embodiment is as follows: if the gray value of the preset point location is within the preset specification range, the gray value is recorded as 1, if the gray value of the preset point location is not within the preset specification range, the gray value of the preset point location is recorded as 0, the final test result can be a group of number sequence consisting of 1 and 0, and if 10 preset point locations are selected, wherein the gray values of the 7 th and 8 th preset point locations are not within the preset specification range, the generated test result is 1110011.
S40, judging whether the output parameters of the light source need to be adjusted or not according to the test result;
in this embodiment, the determination rule may be set to: if the preset point locations with the gray values exceeding the specification range exist in the gray-scale image, the output parameters of the light source in the light box are considered to need to be adjusted, and by combining the embodiment, if the point locations exceeding the specification range exist in the test result, the preset detection requirements are not met, the output parameters of the light source need to be adjusted at the moment, and if the point locations exceeding the specification range do not exist in the test result, the detection requirements are met, and the output parameters of the light source do not need to be adjusted.
In some possible embodiments, the step S40 includes:
step S41, judging whether the light source setting in the light box meets the preset detection requirement or not according to the test result;
it can be understood that the purpose of adjusting the light source in the light box is to ensure the stability of the test environment, thereby ensuring the detection accuracy and detection efficiency in the subsequent detection of the camera to be detected, and avoiding the need of performing point detection and adjustment on the light source in the process of the camera test.
Step S42, if the light source setting in the light box meets the preset detection requirement, the light source in the light box does not need to be adjusted;
it will be appreciated that when it is concluded from the test results that the light source settings in the light box meet the preset detection requirements, there is no need to readjust the light sources in the light box.
Step S43, if the light source setting in the light box does not meet the preset detection requirement, the light source in the light box needs to be adjusted.
It can be understood that when the conclusion obtained according to the test result is that the light source setting in the light box does not meet the preset detection requirement, the light source in the light box needs to be adjusted according to the test result so as to enable the test environment to tend to be stable.
In some possible embodiments, the step S41 includes:
step S411, if the gray value of a certain preset point position in the test result is not within a preset specification range, judging that the light source setting in the light box does not meet the preset detection requirement;
step S412, if the gray values of all preset point locations in the test result are within the preset specification range, it is determined that the light source setting in the optical box meets the preset detection requirement.
For example, the present embodiment can be understood by referring to fig. 3, fig. 3 is a schematic diagram of a grayscale image related to the present embodiment, taking 13 point locations provided in fig. 3 as an example, the data processing PC analyzes the test image, captures points on the test image, reads grayscale values of the point locations, and determines whether the grayscale values are within the specification range, the tested grayscale value data and corresponding specification upper limit and specification lower limit may refer to table 1, as seen from table 1, the test result is that the point locations 10, 11, and 12 are out of the specification range, it is obvious that the light source setting in the light box does not meet the preset detection requirement at this time, and if there is no point location out of the specification range in the test result, it is considered that the light source setting in the light box meets the preset detection requirement.

Step S50, if the output parameters of the light source need to be adjusted, the output parameters of the light source are adjusted, and the step of obtaining the test image of the light box is returned to be executed after the adjustment is finished until the latest test result shows that the output parameters of the light source meet the preset detection requirement;
it should be noted that, in this embodiment, serial port communication has been established between the data processing PC and the light source controller, if the output parameter of the light source needs to be adjusted, the adjusted output parameter is written into the light source needing to be adjusted through the light source controller to adjust the light source, after the adjustment is completed, the industrial camera is controlled to take a picture again to analyze the adjusted image gray value, until the gray value of each preset point in the image is within the specification range, the output parameter of the light source in the light box is considered to have met the preset detection requirement, and the configuration information of the current output parameter of the light source in the light box is uploaded to the data storage system, which is considered to complete automatic point detection and adjustment of each light source in the light box.
In some possible embodiments, the output parameters of the light source include: brightness and/or color temperature; the step of adjusting the output parameter of the light source in step S50 may specifically include:
s51, positioning a corresponding light source based on a preset point position of which the gray value is not within a preset specification range;
step S52, adjusting the brightness and/or color temperature of the light source.
It should be understood that when the light sources in the light box need to be adjusted, not all the light sources need to be adjusted, but only the light source corresponding to the preset point out of the specification range in the gray scale map needs to be selected for adjustment, and when the light source is adjusted, only the brightness, only the color temperature, and also the brightness and the color temperature of the light source may be adjusted, which is not limited in this embodiment.
In some possible embodiments, the light source is connected with a preset light source controller; the step S52 includes: and sending an adjusting instruction to a light source controller corresponding to the light source to adjust the brightness and/or the color temperature of the light source.
It should be understood that the data processing PC cannot directly change the parameter configuration of each light source in the light box, but needs to send an adjustment instruction to the light source controller connected to the light source, so that the light source controller adjusts the brightness and/or color temperature of the corresponding light source according to the adjustment instruction.
And step S60, if the light source in the light box does not need to be adjusted, light source point inspection completion information is generated.
It can be understood that if the light source in the light box does not need to be adjusted, it indicates that the current light source configuration meets the standard for detecting the camera to be detected, the current light source configuration can be directly used as the configuration during detection, and meanwhile, light source spot detection completion information is generated and output to prompt an operator that the light source in the light box meets the preset detection requirement.
