While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Before describing the embodiments, the connection of the image capturing unit, the processing device, and the testing device in the embodiments of the present invention is described, as shown in fig. 1, the image capturing unit 101 and the processing device 102 are connected by a wired or wireless network, and the processing device 102 and the testing device 103 are connected by a wired or wireless network in the embodiments of the present invention. The number of the image pickup units 101 may be one or more, and is not limited herein.
Example one
The embodiment provides a method for testing a camera module, which is applied to a processing device, and as shown in fig. 2, the method includes:
step S201, receiving N initial images sent by N camera units, wherein the N initial images correspond to the N camera units one by one, and N is a natural number;
step S202, extracting local images of a preset area of each initial image in the N initial images, wherein N groups of local images are total, and storing corresponding relation information of the N groups of local images and the N shooting units and first position information of the preset area; the corresponding relation information represents the corresponding relation between the N groups of local images and the N shooting units, and the first position information represents the position information of the preset area on the N initial images;
step S203, sending the corresponding relationship information, the first position information, and the N groups of local images to a testing device.
It should be noted that, in the embodiment of the present application, the camera unit may be an independent camera, or may also be a camera on an electronic product such as a mobile phone or a tablet computer, which is not limited herein; the processing device may be a circuit board, a computer, or a dedicated processing chip, and is not limited herein; the test device may be a circuit board, a computer, or a dedicated processing chip, again without limitation.
The following describes in detail the detailed implementation steps of the method for testing a camera module according to this embodiment with reference to fig. 1:
first, step S201 is executed to receive N initial images sent by N image capturing units, where the N initial images correspond to the N image capturing units one to one, and N is a natural number.
In the embodiment of the present application, N initial images correspond to N imaging units one to one, which means that: each of the N image pickup units picks up and acquires an initial image, and the N image pickup units acquire N initial images in total, wherein each image pickup unit corresponds to the initial image picked up and acquired by the image pickup unit.
In a specific implementation process, the N image capturing units may transmit the N initial images to the processing device in parallel, may transmit the N initial images to the processing device in series, and may transmit the N initial images to the processing device in partial series and partial parallel, which is not limited herein.
Specifically, after receiving N initial images, the processing device buffers the N initial images for the subsequent step S202.
Then, step S202 is executed to extract local images of a preset region of each of the N initial images, N sets of local images are total, and correspondence information between the N sets of local images and the N imaging units and first position information of the preset region are stored.
Before extracting the local image, the extracted preset region needs to be determined, and in the specific implementation process, there may be a plurality of methods for determining the preset region, which are listed as two examples below:
first, it is determined based on the parameter to be tested.
Firstly, receiving parameters to be tested, and then determining a preset area according to a preset rule based on the parameters to be tested.
Specifically, the processing device may receive the parameters to be tested sent by the testing device in advance, or may receive the parameters to be tested input by the tester on the processing device, which is not limited herein.
The method for determining the preset area based on the parameters to be tested may be: and presetting corresponding information of the test parameters and the preset area, and determining the preset area according to the corresponding information after the processing equipment receives the parameters to be tested.
For example, a preset region corresponding to the test definition may be preset as a middle region of the image, a preset region corresponding to the test edge imaging parameter is an edge region of the image, and a preset region corresponding to the test corner exposure parameter is four corner regions of the image. And when the parameters to be tested received by the processing equipment are corner exposure parameters, determining the preset areas as four vertex angles of the N initial images.
And secondly, the operation is determined according to the input operation of a tester.
That is, an input operation for determining a preset region is received first, and then the preset region is determined based on the input operation.
Specifically, the input operation may be an operation in which a user inputs coordinate data of a preset region to cause the processing device to determine the preset region from the coordinate data; the input operation may also be an operation selected by the user among options such as "middle", "edge", "four corners", "left side", "right side", and the like displayed, so that the processing device determines the preset region according to the region option selected by the user; the input operation may also be an operation of a user moving a mouse or sliding a finger on the displayed virtual image to make the processing device use the area circled by the user as a preset area, which is not limited herein.
Of course, in the specific implementation process, the methods for determining the preset region are not limited to the above two methods, and different methods for determining the preset region may be selected according to the test requirement, which are not limited herein and are not listed.
After the preset area is determined, the processing device extracts the image in the preset area on each image in the N initial images as the local image corresponding to the extracted image, and N groups of local images are extracted from the N initial images correspondingly. In a specific implementation, there may be one or more partial images in each group of partial images according to the testing requirement.
Further, the processing equipment stores the corresponding relation information of the N groups of local images and the N camera units, so that the subsequent testing equipment can distinguish the image testing result parameters of each camera unit; the processing device also stores first position information representing positions of the preset area on the N initial images, so that a subsequent testing device can restore a restored image for testing according to the N groups of local images.
For example, the recording format of the correspondence information may be K-n, where n is a reference number of a certain partial image, and K is a reference number of an image capturing unit corresponding to the partial image. The first position information may be recorded in the form of n-x, y, z, o, n being the index of a local image, and x, y, z, o being the coordinates of the four vertex positions of the local image on the initial image corresponding to the local image. Of course, the recording form of the first position information may also be n-m, where n is a mark number of a certain partial image, and m is a position mark number preset on the initial image corresponding to the partial image, and the position mark number may be a number, a letter, or other symbols, which is not limited herein.
In the embodiment of the present application, it is considered that if N groups of local images are directly sent to the testing device, in order to distinguish each local image, it is often necessary to add a mark bit at the beginning and the end of each image, so that each local image can be separated, and setting and adding the mark bit consumes more computing resources, which also prolongs the processing time, thereby reducing the testing efficiency. And considering that image data may be mixed with control data (such as I2C data) for transmission, the control data also needs to insert a flag signal to help distinguish, and too many flag signals reduce transmission efficiency and increase processing complexity.
In order to solve the above problem, the present embodiment further includes, after extracting N groups of partial images: and splicing the N groups of local images into a target image, and further, storing second position information of the N groups of local images on the target image by the processing equipment, and sending the corresponding relation information, the first position information, the second position information and the target image to the testing equipment, so that the subsequent testing equipment can split the N groups of local images from the target image according to the second position information.
In the specific implementation process, there are many methods for stitching N groups of local images into a target image, and two methods are listed as follows:
first, random splicing.
Namely, each partial image in the N groups of partial images is spliced together randomly to form a target image. And recording the position of each local image on the target image and storing the position as second position information.
For example, n-a, b, c, and d are recorded in the second position information, where n is a label of a local image, and a, b, c, and d are coordinates of four vertices of the local image on the target image. Of course, the recording form of the second position information may also be n-k, where n is a mark number of a certain partial image, and k is a preset position mark number of the partial image on the target image, and the position mark number may be a number, a letter, or other symbols, which is not limited herein.
And secondly, splicing each group of local images firstly and then splicing all the local images.
The same group of local images are spliced firstly, and then the spliced images of each group are randomly spliced to form a target image. And recording the position of each group of local images on the target image and storing the position information to second position information.
Of course, in the specific implementation process, other splicing manners may also be adopted, and are not limited herein.
A method for restoring and testing the target image or the N sets of partial images after the test device receives the target image or the N sets of partial images is described in detail in embodiment two.
Specifically, network transmission resources occupied when image data are sent to test equipment are reduced by transmitting the extracted local images instead of the complete images shot by the camera units, so that a plurality of camera units can be tested simultaneously, and the test efficiency is improved. Furthermore, by transmitting continuous target images instead of N groups of local images, the problems of high calculation overhead and time-consuming processing caused by the fact that the N groups of local images are transmitted respectively and are segmented by inserting mark bits between the local images of the cameras can be avoided, and the testing efficiency is effectively improved.
Based on the same inventive concept, the application also provides a method of the testing device side in fig. 1 corresponding to the embodiment, which is described in detail in the second embodiment.
Example two
The embodiment provides a method for testing a camera module, as shown in fig. 3, where the method is applied to a testing apparatus, and includes:
step S301, receiving corresponding relation information, first position information and N groups of local images sent by processing equipment; the corresponding relation information represents the corresponding relation between the N groups of local images and N camera units, wherein N is a natural number;
step S302, according to the first position information and the N groups of local images, restoring to obtain N restored images corresponding to the N groups of local images one by one;
step S303, testing the N restored images to obtain N groups of test result parameters which are in one-to-one correspondence with the N restored images;
step S304, determining the test result parameters of each camera unit in the N camera units according to the corresponding relation information and the N groups of test result parameters.
The following describes in detail the detailed steps of the method for testing the camera module on the testing device side with reference to fig. 3:
firstly, executing step S301, receiving corresponding relation information, first position information and N groups of local images sent by a processing device; the correspondence information represents the correspondence between the N groups of partial images and N imaging units, where N is a natural number.
In view of the detailed description of the first embodiment, the corresponding relationship information, the first position information, and the N groups of local images, for the sake of brevity of the description, a description thereof will not be repeated here.
It should be noted that, if the test device receives a target image formed by splicing N groups of partial images, the test device also receives second position information sent by the processing device, where the second position information represents positions of the N groups of partial images on the target image, so that the test device splits the N groups of partial images from the target image according to the second position information.
Then, step S302 is executed to restore and obtain N restored images corresponding to the N groups of partial images one to one according to the first position information, the correspondence information, and the N groups of partial images.
For example, the recording format of the correspondence information may be K-n, where n is a label of a local image, K is a label of an image capturing unit corresponding to the local image, the local images that are the same as K are confirmed to be local images in the same group, and then first position information of the local images in the same group is obtained, assuming that the first position information format is n-m, where n is a label of the local image, and m is a position label of the local image on a corresponding initial image. And restoring the same group of partial images to the same restored image according to the first position information according to the mark number n and the corresponding m position mark number, specifically, the m position mark number may be marked by 1 to 9 as shown in fig. 4, or may be marked by a letter or other symbols, which is not limited herein.
Specifically, the N restored images obtained by restoring are not exactly the same as the N original images in the first embodiment, and only a partial image of a preset area is included in the N restored images, and the rest of the areas may be set to be blank or transparent. For example, as shown in fig. 4, a is an initial image, b is an extracted local image which is an image of four corners of the initial image, c is a restored image, and the remaining area of the restored image except the local image is displayed in a solid color.
It should be noted that, if the target image formed by splicing the N groups of partial images is received in step S301, before the N restored images are restored, the N groups of partial images need to be split from the target image according to the second position information. For example, the second position information may be n-a, b, c, d, where n is a label of a local image, and a, b, c, d are coordinates of four vertices of the local image on the target image, and the local image is extracted according to a, b, c, d and labeled as n.
After the N restored images are restored, step S303 is executed to test the N restored images, and N sets of test result parameters corresponding to the N restored images one to one are obtained.
In a specific implementation, the test result parameter may be a hue, a sharpness, a brightness, or the like, and is not limited herein.
Then, step S304 is executed to determine a test result parameter of each of the N image capturing units according to the correspondence information and the N sets of test result parameters.
For example, the form of the correspondence information is K-n, n is a label of a certain local image, K is a label of the camera unit corresponding to the local image, and after the test restored image a is assumed to obtain the test result parameter b, the label K of the corresponding camera unit can be determined by referring to the correspondence information K-n according to the label n of the local image on the restored image a, so that the test result parameter b is determined to be the test result parameter corresponding to the camera unit of the label K.
Specifically, in the embodiment of the present invention, a local image is extracted from each of N initial images sent by N received image capturing units, and the N groups of extracted local images, first position information of a preset region of the extracted local images, and correspondence information of the local images and the image capturing units are sent to a test device together, so that the test device can restore the N initial images to perform a test based on the first position information and the N groups of local images, and determine a test result parameter of each camera according to the correspondence information. The extracted local image is transmitted instead of the complete image shot by the camera shooting unit, so that network transmission resources occupied when the image data are sent to the test equipment are reduced, a plurality of camera shooting units can be tested at the same time, and the test efficiency is improved.
Furthermore, the embodiment of the present invention splices N groups of extracted local images into a target image, and sends the target image and second position information of the N groups of local images on the target image to the test equipment, so as to replace the N groups of local images by transmitting consecutive target images on the basis of ensuring that the test equipment can restore the target image based on the second position information, thereby avoiding the problems of large computation overhead and time-consuming processing caused by the need of inserting a marker bit between the local images of each camera to divide the N groups of local images, and effectively improving the test efficiency.
