However, when using the nine-point test method, the selection of different pixel positions will affect the subsequent calculation results, and the inaccurate test results will be caused when the selected point position is inappropriate.
Moreover, the current TV sets are all curved TV sets, and the current test method is aimed at regular-shaped rectangular TV sets. The measurement method for curved TV sets also uses the measurement method for regular-shaped rectangular TV sets, which will also affect the uniformity of the results. Evaluate

Embodiment Construction
[0052] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0053] The main idea of the solution in the embodiment of the present invention is as follows: when a white test picture is played on the test screen, the test screen is photographed, a test image is obtained, and a test template corresponding to the size of the test image is obtained; Perform low-pass filtering and high-pass filtering to obtain a test low-pass image and a test high-pass image; superimpose the test low-pass image and the test template to obtain a test low-pass superimposed image, and superimpose the test high-pass image and the test template to obtain a test. High-pass overlay image, and respectively obtain test low-pass pixel data and test high-pass pixel data according to the test low-pass overlay image and test high-pass overlay image; perform the test low-pass pixel data, test high-pass pix...

The invention discloses a display screen uniformity testing method, and the method comprises the steps: shooting is performed when a testing screen plays a test image, the test image is acquired, and a corresponding test template is also acquired; filtering processing is performed on the test image, and a test low-pass image and a test high-pass image are acquired; the test low-pass image and the test template are superposed to obtain a test low-pass superposed image, the test high-pass image and the test template are superposed to obtain a test high-pass superposed image, and corresponding test low-pass pixel data and test high-pass pixel data are obtained; the test low-pass pixel data, the test high-pass pixel data and preset reference data are compared, and a test result of the testing screen uniformity is determined according to a comparison result. The invention also discloses a display screen uniformity test terminal and a computer readable storage medium. According to the invention, the accuracy of the display screen uniformity test is improved, the test time consumption is reduced, and the uniformity test efficiency is improved.
Description
technical field [0001] The present invention relates to the technical field of display screen testing, in particular to a display screen uniformity testing method, a terminal and a computer-readable storage medium. Background technique [0002] The brightness uniformity of the display screen reflects the quality of the display screen. If the display screen is uniform, the image display effect is good; if it is not uniform, the display effect is poor, and the displayed image will appear various traces. [0003] The traditional test method for the uniformity of the display screen is to use the combination of human vision and a luminance meter to judge the uniformity of the display. Since this method utilizes people's subjective feeling, it is easy to affect the evaluation result due to the difference of subjective feeling. Another common test method is the nine-point test method, that is, according to the brightness of the surrounding 8 pixels and the center pixel, the unifor...
