Problems solved by technology
Its disadvantages are: in production practice, defect samples usually have less data, which is not conducive to the construction of deep learning data sets. The model trained with a small number of sample images generally has limited adaptability; moreover, the shape and size of defects are random and irregular. If the types of defects are manually defined and divided, then It is easy to cause incomplete classification coverage; therefore, due to the lack of defect sample images, if there are defects not covered by the data set at the same time, it will cause missed detection
Furthermore, the image segmentation method of deep learning requires high computing resources, and usually takes more than 1 second, which will affect the detection efficiency
[0004]
In summary, there are many problems in the actual use of existing methods, so it is necessary to improve

The invention provides a mobile phone middle frame edge appearance defect detection method. A to-be-detected image of a mobile phone middle frame is acquired; intercepting a middle frame edge image of a preset ROI region in the to-be-detected image; performing binarization threshold processing on the middle frame edge image, and extracting a target image with a preset pixel height; and according to the pixel value statistical information of the target image in the vertical projection, screening out the edge appearance defect. The invention further provides a mobile phone middle frame edge appearance defect detection system, a storage medium and computer equipment. Therefore, the appearance defect of the edge of the middle frame of the mobile phone can be accurately detected, and meanwhile, the detection cost is lower and the detection efficiency is higher.
Description
technical field [0001] The invention relates to the technical field of product inspection, in particular to a method, a system, a storage medium and a computer device for detecting appearance defects on the edge of a middle frame of a mobile phone. Background technique [0002] The middle frame of the mobile phone refers to the middle plate between the mobile phone screen and the battery; in the production and manufacturing, it is easy to cause the appearance defect of the edge of the middle frame of the mobile phone, and the edge appearance refers to the exposed side of the external screen of the mobile phone, and the width visible to the naked eye is about 1mm. The appearance of the edge part of the middle frame. For this reason, it is necessary to detect the edge appearance defects of the middle frame of the mobile phone in the production process. [0003] The solution provided by the existing technology is to collect good product images and defect images, make a data se...
