determining shooting parameters corresponding to the screen by identifying the content to be detected in the first image;
controlling a camera to acquire a screen displaying the content to be detected based on the shooting parameters to obtain a second image; and
determining whether the screen passes a test based at least on the second image.
7. The test device of claim 6, wherein the content to be detected includes an identification area for identifying device information of the screen, and the determining the shooting parameter corresponding to the screen by identifying the content to be detected in the first image includes:
identifying the identification area to determine device information of the screen; and
determining a photographing parameter corresponding to the screen based on the device information.
8. The test device of claim 6, wherein the processor is further configured to:
after the shooting parameters corresponding to the screen are determined, processing the first image, and determining an image definition metric value; and
and adjusting focusing parameters on the basis of the shooting parameters on the basis of the image definition metric value.
9. A computer readable storage medium having computer readable instructions stored thereon which, when executed by a processor, cause the processor to:
controlling a production line to move electronic equipment with a screen to a target detection position and triggering the electronic equipment to display the content to be detected through the screen;
controlling a camera to acquire a screen displaying content to be detected to obtain a first image;
determining shooting parameters corresponding to the screen by identifying the content to be detected in the first image;
acquiring a screen displaying the content to be detected based on the shooting parameters to obtain a second image; and
determining whether the screen passes a test based at least on the second image.
10. An apparatus for testing a screen of an electronic device, comprising:
the first control module is used for controlling a production line to move the electronic equipment with the screen to a target detection position and triggering the electronic equipment to display the content to be detected through the screen;
the second control module is used for controlling the camera to acquire a screen displaying the content to be detected to obtain a first image;
the first determining module is used for determining shooting parameters corresponding to the screen by identifying the content to be detected in the first image;
the third control module is used for controlling the camera to acquire and display a screen of the content to be detected based on the shooting parameters to obtain a second image; and
a second determination module to determine whether the screen passes a test based at least on the second image.
