Appearance detection system based on machine vision

Abstract

The invention relates to an appearance detection system based on machine vision. The system comprises a line-scan digital camera scanning system, a transmission system and a plurality of shooting systems, wherein the line-scan digital camera scanning system comprises a scanning and shooting component and a horizontal movement component, the scanning and shooting component is arranged on the horizontal movement component and is driven to carry out horizontal scanning and shooting in a horizontal direction by the horizontal movement component; the plurality of shooting systems are respectively arranged at a proper position close to an object to be shot, each shooting system comprises an area-array camera shooting system and a prism group system, and the area-array camera shooting system reflects multiple faces of the object to be shot to carry out multi-face shooting through the movement of the prism group system; and the transmission system comprises a conveying roller way and a positioning mechanism and is used for conveying and positioning the object to be shot. According to the system, the inner and outer sides and the surfaces with various inclination angles of the object to beshot can be shot, the shooting frequency and time can be effectively reduced, a shooting process is simplified, and the shooting cost is reduced.

Description

technical field [0001] The invention relates to the technical field of industrial inspection, in particular to an appearance inspection system based on machine vision. Background technique [0002] At present, with the development of automation and intelligence in the industry, more and more industrial cameras based on machine vision are used in automatic production lines. Use industrial cameras to shoot products, and after the captured images are collected, processed, and analyzed, the obtained data can realize functions such as detection, measurement, supervision, identification, and positioning. However, at present, it is difficult for industrial area scan cameras to complete comprehensive inspections for range hoods and other outer casings with relatively complex shapes and multiple inner surfaces that need to be inspected. The industrial area array camera can only photograph one outer surface of the object at a time, and the area array camera cannot directly photograph...

AI Technical Summary

Problems solved by technology

Although some people have invented related detection systems, they all require a combination of multiple area array cameras or a complex mechanical arm to control the movement of the area array camera or control the movement of the object to be photographed.

These methods or inventions make the shooting process more complicated, increase the cost of shooting, and have shortcomings such as lack of universality for objects to be shot with different specifications.
