Problems solved by technology

In the entire product development process, artificially controlled testing methods consume a lot of human resources, and lead to high product development costs, long cycles, and unreliable test results, which may even lead to serious consequences such as product quality decline.
Therefore, the existing human-controlled test methods have been difficult to meet the needs of practical applications

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0022] see figure 1 , is a schematic structural diagram of the first embodiment of an image-matching-based automatic testing system provided by the present invention.

[0023] In the first embodiment, the automatic test system based on image matching includes a test terminal 100 and an image acquisition device 200 .

[0024] Wherein, the test terminal 100 stores the color coding values ​​of each pixel of the normal output image of the display device 300 under test.

[0025] The testing terminal 100 is configured to send a control signal to the display device under test 300 to control the display device under test 300 to output corresponding images.

[0026] During specific implementation, the test terminal 100 first stores the normal output images of all display interfaces o...

Abstract

The invention discloses an automatic test system based on image matching. The automatic test system comprises a test terminal and an image acquisition device. The image acquisition device is used for acquiring an actual output image of a display device to be tested and transmitting the actual output image to the test terminal, and the test terminal is used for receiving the actual output image, intercepting a designated area image of the actual output image, analyzing the designated area image, acquiring color coding values of pixels of the designated area image of the actual output image and judging whether the actual output image is matched with a normal output image or not. By the automatic test system based on image matching, time-consuming, repeated and mechanical man-machine interactive operation is avoided, the test efficiency and the test quality for the display device are improved, and the production cost of the display device is further reduced.

Description

technical field [0001] The invention relates to the technical field of display device testing, in particular to an automatic testing system based on image matching. Background technique [0002] At present, most of the products in the field of digital TV technology, such as monitors, TV sets, set-top boxes, advertising machines, etc., usually need to perform performance tests on their items in order to ensure the system performance of the products during the development process. [0003] Display devices refer to devices that transmit and process information in the form of visible light. Currently, display devices mainly include monitors, televisions, and various video playback terminals. [0004] At present, the test process of the receiving performance index of the existing display device is very cumbersome. The main test method is to control the test of each item of the display device by manipulating the keypad or infrared remote control, etc., and subjectively judge the ...
