Relying on the "Special Support Plan for Entrepreneurship + Industrial Chain Integration", the members of the research team carried out research on the visual detection and positioning methods of smart TV production lines, and realized the related systems of industrial visual detection, including (1) small target defect detection, research has Strong discriminative features to describe small defects, used to detect and locate small defects. (2) Dynamic defect detection, research on dynamic defect detection methods with strong practicability. (3) Detection of new defects and regions of interest, researching flexible feature representations and methods of adding and deleting new defects and regions of interest. In addition, the research group has established a comprehensive test database for industrial visual inspection and positioning in the fields of smart TVs and intelligent robots, and the detection speed and accuracy of target areas such as small defects and motion defects have reached the leading level.
