Zusammenfassung: | The invention relates to the technical field of scratch detection, in particular to an electronic equipment surface scratch detection system based on visual identification, which comprises an image feature analysis module, a scratch confidence coefficient analysis module and a scratch result analysis module, the image feature analysis module is used for analyzing image data and performing edge detection and texture and shape analysis on the image data to obtain feature vectors and feature description values; the scratch confidence analysis module is used for predicting confidence according to the feature vectors in the image feature analysis module by utilizing a logistic regression algorithm; the scratch result analysis module sets the threshold value of the feature description value and the threshold value of the confidence coefficient, compares the feature description value and the confidence coefficient with the corresponding threshold values, determines a scratch result according to a comparison result, |
