Abstract

The embodiment of the invention provides a product quality detection method and device and electronic equipment. The method comprises the following steps: acquiring a shot original image of a to-be-detected product and a binarization threshold corresponding to the to-be-detected product by detection equipment, and performing binarization processing on the original image according to the binarization threshold. The detection equipment can perform de-noising processing on first pixel points according to binarization values of multiple second pixel points adjacent to the first pixel points, namely binarization values corresponding noisy points subjected to binarization processing are adjusted, so that the influences of the noisy points in the image on the accuracy of subsequent product scratch detection are avoided. Finally, the detection equipment determines whether the image subjected to de-noising processing contains scratches. The product quality detection method is totally executed by the detection equipment, the detection equipment detects the quality of the to-be-detected products by adopting the unified detection standard, human intervention does not exist in the detection process, and the product quality detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a product quality detection method, device and electronic equipment. Background technique [0002] In the process of product manufacturing, due to the influence of many factors such as production environment, production equipment and production process, the appearance of product defects is inevitable. Common product defects include surface cracks, scratches, and more. In order to avoid quality problems during the use of the product after leaving the factory, it is necessary to perform product quality testing before the product leaves the factory. [0003] In the prior art, the commonly used detection method is mainly manual detection, but manual detection is highly subjective, and there is no uniform detection standard in the process of manual detection, which greatly reduces the accuracy of detection. Contents of the invention [0004] In view of this, the embodi...
