Description

Automobile part surface defect detection structure based on machine vision
Technical Field
The utility model relates to an automobile inspection specifically is an automobile class spare part surface defect detects structure based on machine vision.
Background
In recent years, with the rapid development of electronic technology and computer technology, the software and hardware technology of machine vision is also rapidly developed, and an optimal scheme is provided for online detection of surface defects of products. The use of "machines" to replace the human eye for surface defect detection has become an important trend in the development of modern industry. The detection of the surface defects of the product by using machine vision has a plurality of advantages in terms of technical performance and technical indexes. Firstly, machine vision is a non-contact and non-destructive test, which is safe and reliable. Secondly, if the indexes of the camera are used for analyzing human eyes, the machine vision can replace the human eyes and surpass the human eyes, and the detection with more powerful functions and high efficiency is realized.
The existing CCD camera can achieve higher resolution ratio through a multi-chip splicing technology, and the response speed of an imaging device greatly exceeds the limit of human eyes. At present, the machine vision technology is relatively mature in foreign research and application and widely applied to various fields such as measurement, navigation, identification, detection and the like. Although the application of machine vision is also provided in China, the machine vision is often applied to occasions of low-speed and small systems such as traffic monitoring, character recognition, product sorting and the like.
The existing machine vision part detection mainly adopts binocular vision detection, the binocular vision detection can improve the accuracy through image comparison, and has more outstanding precision performance in low speed and small occasions, but for large-scale operation assembly line work, the binocular vision detection is lower in detection rate due to the fact that two or more cameras are needed, and the actual requirements of large-scale operation are difficult to meet. The monocular vision detection saves the image comparison time, and has higher efficiency and economic benefit in medium-high speed and large-scale detection.
Line structure light can realize accurate, quick 3D measurement and data acquisition, uses the object extensively, no matter be reflection of light metalwork, black cast member or high temperature forging, line structure light scanning all can accomplish established requirement to do not influenced by ambient light. However, the line structured light has a high requirement for accurate calibration of the CCD camera, and when the camera calibration has a deviation, the line structured light scanning may cause a scanning result to have a structural deviation, thereby affecting actual judgment.
