The invention discloses a plate defect detection system and method based on multi-feature fusion. The system comprises an image acquisition and preprocessing module, a chromaticity coordinate and texture feature acquisition module and a defect detection marking module. The image acquisition and preprocessing module acquires image information of a target board and preprocesses the image information; the chromaticity coordinate and texture feature acquisition module calculates the preprocessed image information to obtain a chromaticity library and a texture defect model; and the defect detection marking module is used for detecting defects in the image information and marking the positions of the defects. The plate defect detection system is established, the chromaticity library and the texture feature model are established in an image processing mode, the processing speed is high, the precision is high, and the visual effect is good.
Description
technical field [0001] The invention relates to the technical field of defect detection, and more particularly, to a plate defect detection system and detection method based on multi-feature fusion. Background technique [0002] In recent years, with the continuous improvement of people's living standards, people's demand for wood materials is increasing. In the decoration market, due to the increasing scarcity of wood resources and the easy generation of various defects in the growth process of wood, the supply of high-quality wood is in short supply, resulting in a continuous increase in the price of natural wood. Therefore, in order to improve the comprehensive utilization rate of wood and reduce the price of panels, artificial wood panels are made from wood and other non-wood plants. Artificial wood panels mainly include three types of products: plywood, particleboard and fiberboard, and their surfaces need to be decorated with imitation wood grains to meet practical re...
