Abstract

The invention discloses a surface quality detecting system and method for automobile covering parts. The surface quality detecting system is characterized in that a CCD camera and a light source are symmetrically fixed to the upper part of a detecting worktable, the signal output end of the CCD camera is connected with the signal input end of an analog signal processor, the output end of the analog signal processor is connected with the signal input end of a DSP signal processor through an A / D conversion circuit, the signal output end of the DSP signal processor is connected with the signal input end of a detecting module, the detecting module is composed of a cracking defect detecting module, a scratch defect detecting module and an indentation defect detecting module, and the light source is controlled through a light source controller. The surface quality detecting method comprises the steps that a controller controls the detecting worktable to rotate leftwards along the center line; left detecting images are output; right detecting images are output; and cracking defects, scratch defects and indentation defects of the automobile covering parts are detected. The surface qualitydetecting system and method have the advantages that the detecting efficiency is high, and the accuracy rate is high.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, and in particular relates to a surface quality detection system and method of an automobile cover part. Background technique [0002] Human beings perceive the external world mainly through sensory organs such as vision, touch, hearing and smell, and vision is the most important sensory function of human beings. According to statistics, more than the external information perceived by people is obtained by vision. To put it simply, machine vision can be understood as adding a visual device to the machine, so that the machine has the function of "vision", and replaces the human eye in some fields for measurement and judgment, so that it can recognize and understand the observed things , which can determine the position of the target within the range it sees. Machine vision is not only an extension of the human eye, but also has some functions of the human brain. The purpose is to impr...
