Abstract

The present invention discloses a product image detection method and comparison device capable of automatically distributing light. The method comprises: collecting feature information of a workpieceto be tested, wherein the feature information including feature points and contour information; determining location information of the workpiece to be tested according to the feature information, wherein the location information includes a placement angle and center coordinate information of the workpiece to be tested; acquiring a preset workstation of a manipulator arm corresponding to the feature information, and light distribution schemes, and determining an actual workstation of the manipulator arm according to the location information and a preset workstation, wherein the light distribution scheme includes irradiation distance and irradiation angel of a light source of a light distribution subsystem; collecting an actual image of the workpiece to be tested by using a corresponding light distribution scheme at least at the actual workstation; and comparing the actual image with a corresponding standard image of a standard workpiece to generate a comparison result. The device applies the method. The method and device can ensure acquisition efficiency of the actual image, and brightness and clarity of the image.

Description

technical field [0001] The invention relates to the field of automatic detection, in particular to a product image detection method and a comparison device capable of automatic light distribution. Background technique [0002] In the process of factory production process, it is difficult to meet the actual needs by only relying on manual inspection of product quality. Now the existing machine vision image processing technology has been more and more widely used in manufacturing enterprises. The current machine vision image comparison and detection equipment basically relies on the embedded system integration technology for visual image acquisition, visual image processing and control. [0003] The above-mentioned embedded system is the fusion of machine vision system and other sensor technologies, and the advantage is to solve the limitations of a single vision system. However, due to its high degree of integration, when faced with changes in the measurement and control obj...
