Zusammenfassung:The invention relates to a system and method for detecting surface defects of an object, and the system for detecting the surface defects of the object comprises a multi-angle hardware mobile platform which is used for driving the object placed on the platform to translate along at least one of an X axis and a Y axis or rotate in an X-Y plane, and a laser profile measuring instrument which is used for collecting a picture of the object, and the computing equipment runs a supervised-learning-unsupervised neural network model and is used for comparing the acquired picture with the trained positive sample picture so as to identify the surface defect of the object. The model is trained by a positive sample to obtain a positive sample representation, and the model compares a collected object picture with the positive sample representation to identify the surface defect of the object. Compared with traditional manual quality inspection, the method has the advantages that potential safety hazards caused by repeated
