Defect detection method, device and equipment for mobile phone touch screen and storage medium

Abstract

The invention relates to the field of artificial intelligence, and discloses a defect detection method, device and equipment for a mobile phone touch screen and a storage medium, which are used for improving the defect detection accuracy of the flexible mobile phone touch screen. The method comprises the following steps: performing defect information labeling on a plurality of training images to generate a sample image data set; generating an enhanced image data set according to the sample image data set; performing model training on the training model according to the enhanced image data set to obtain a mobile phone touch screen defect detection model; the method comprises the following steps: acquiring an initial folding image and an initial stretching image of a to-be-detected flexible mobile phone touch screen, and carrying out image preprocessing on the initial folding image and the initial stretching image to obtain a target folding image and a target stretching image; and inputting the target folding image and the target stretching image into a mobile phone touch screen defect detection model for crease detection to obtain a crease detection result.

Description

technical field [0001] The invention relates to the field of artificial intelligence, and in particular, to a defect detection method, device, equipment and storage medium for a touch screen of a mobile phone. Background technique [0002] With the continuous development of science, technology and industrial level, people's quality requirements for LCD screen products such as mobile phone screens are also increasing. A flexible mobile phone touch screen is a bendable mobile phone screen. In order to produce a high-quality, high-resolution flexible mobile phone touch screen, quality inspection of the flexible mobile phone touch screen during the production process is an essential process, which includes judging the flexibility of the mobile phone touch screen. Whether there is a crease defect on the touch screen of a mobile phone, and the classification and grading of the detected defect. Therefore, how to quickly and accurately detect the screen defects of flexible mobile p...

Problems solved by technology

[0003] The traditional manual inspection method is to rely on the human visual function to detect the screens on the production line one by one, but the detection efficiency of the manual detection method is not high, and the creases of some flexible mobile phone touch screens cannot be displayed in the folded state, as long as they are stretched. It can only be detected when it is detected, which seriously affects the production efficiency of the screen; and different people have different defect standards for the flexible mobile phone touch screen, that is, the same screen has different test results, so the accuracy of manual defect detection is not high.
