Abstract

The invention provides a workpiece detection system which is used for detecting surface defects of workpieces and comprises a conveying belt, a first detection assembly and a second detection assembly, and the conveying belt sequentially penetrates out of the first detection assembly and the second detection assembly in the first direction. The first detection assembly comprises a line scanning camera and a first light source, and the line scanning camera and the first light source are arranged towards the conveying belt. The second detection assembly comprises a plurality of first area-array cameras and a second light source, and the first area-array cameras and the second light source face the conveying belt. The first detection assembly and the second detection assembly are used for detecting different defects of the workpiece. According to the workpiece detection system, multiple groups of images of the workpiece are obtained from different angles by arranging the multiple detection assemblies, adopting multiple devices and matching with different light sources so as to be used for detecting different defects. The invention also provides a workpiece detection method.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a workpiece detection system and method. Background technique [0002] For the production and manufacturing work, quality inspection is required for the produced products to ensure the yield of the products and to avoid the mixing of defective products. [0003] For example, a product such as a mobile phone case needs to be inspected for surface defects. Specifically, it involves the detection of different shapes on the product and the judgment of different defects, such as scratches, knife marks, different colors, sagging and other defects for large planes, sides, gaps, rounded corners and other shapes. Due to the complexity of the specific situation, it is usually necessary to conduct a comprehensive inspection by means of manual detection and judgment, which brings high labor intensity and labor cost, and at the same time, the work efficiency is low. ...
