Description

technical field [0001] The invention relates to defect detection technology, in particular to a method, system and device for detecting significant defects on the leather surface. Background technique [0002] Explanation of technical terms: [0003] Gabor filter: refers to a two-dimensional Gabor filter formed using the Gabor function, a linear filter for edge extraction. [0004] SVM: Refers to Support Vector Machine. [0005] In the production process of leather products such as leather bags, car seats, clothes, etc., quality control is particularly important. Therefore, leather is the raw material of these leather products, and its defect detection and positioning is an important task of quality control. At present, the detection of leather defects in the industry mainly relies on human eyes. However, the noisy factory environment, a large amount of inspection work, and the variety of leather defects make it difficult to meet the quality control requirements by relying...
