Abstract
The invention discloses a light source regulation method for LCD glass substrate defect detection. Two white papers are used for determining a reference plane where a lighting area is and a datum lineperpendicular to a motion direction, a reflected lighting area of a reflected light source and transmission light area of a transmission light source are overlapped at the datum line and parallel tothe datum line, and perpendicular to a motion direction of a motion platform. The light source regulation method provided by the invention simple and efficient, has high repeatability, is beneficial for operation of experimenters, is beneficial for regulating a light source in practical application, and can be generalized in light source regulation of all robot vision system.
