Problems solved by technology

[0002] The brake pads used in automobiles not only have strict requirements on materials and sizes, but also strictly control surface defects. The surface defects of the pads mainly include cracks, cracks, scratches, defects, indentations and burrs, etc., which affect the reliability of the braking system. These defects are often the cause of slow braking, increased braking distance, and even brake failure accidents, which in turn lead to car rear-end collisions, collisions, collisions with obstacles, or collisions with people, resulting in serious damage to the vehicle and accidents. The phenomenon of fire or even explosion, so th

Embodiment

[0019] refer to Figure 1-2 , the present embodiment proposes an automatic sorting system for detecting surface defects of automobile brake pads based on machine vision. Picking the arm, the upper computer includes image preprocessing, image segmentation, feature extraction and pattern recognition, pattern recognition includes color recognition, shape recognition, texture recognition and multi-feature fusion recognition. The brake pads are tested, and the detection results are used to control the action of the sorting arm, and the defective brake pads are sorted to the unqualified area, and the qualified products are processed in the factory, so as to achieve the purpose of automatic sorting and facilitate use.

[0020] In this embodiment, the machine vision system detects the image of the object to be sorted and transmits the information to the CPU. The CPU processes the received information, and the CPU transmits the information to the host computer. The host computer perfor...

Abstract

The invention discloses a car brake pad surface defect detecting and automatic sorting system based on machine vision. The system comprises a machine vision system. The machine vision system comprisesa camera, a camera lens and a light source. The machine vision system is connected to a CPU. The CPU is connected with an upper computer and a sorting arm. The upper computer involves image preprocessing, image segmentation, feature extraction and mode recognition, mode recognition involves color recognition, shape recognition, texture recognition and multi-feature fusion recognition, the machinevision system detects a to-be-sorted target image and transfers information to the CPU, and the CPU processes the received information. The car brake pad surface defect detecting and automatic sorting system based on machine vision is reasonable in design, brake pads are conveniently detected through image acquisition, processing and recognition, the sorting arm is controlled to act by means of detecting results, brake pads with detects are sorted to an unqualified area, qualified products leave a factory, the purpose of automatic sorting is achieved, and using is facilitated.

Description

technical field [0001] The invention relates to the technical field of an automatic sorting system for detecting surface defects of automobile brake pads, in particular to an automatic sorting system for detecting surface defects of automobile brake pads based on machine vision. Background technique [0002] The brake pads used in automobiles not only have strict requirements on materials and sizes, but also strictly control surface defects. The surface defects of the pads mainly include cracks, cracks, scratches, defects, indentations and burrs, etc., which affect the reliability of the braking system. These defects are often the cause of slow braking, increased braking distance, and even brake failure accidents, which in turn lead to car rear-end collisions, collisions, collisions with obstacles, or collisions with people, resulting in serious damage to the vehicle and accidents. The phenomenon of fire or even explosion, so the brake pads need to be tested during the produ...
