Abstract

The invention discloses a product image detection method capable of automatic light distribution and a comparison device. The method includes: collecting feature information of a workpiece to be tested, and the feature information includes feature points and contour information; according to the feature information, Determine the position information of the workpiece to be measured, the position information includes the placement angle and center coordinate information of the workpiece to be measured; obtain the preset position of the manipulator corresponding to the feature information and the light distribution scheme, according to the position information and the preset Set the station to determine the actual station of the manipulator, the light distribution scheme includes the light source irradiation distance and angle of the photodistribution subsystem; at least at the actual station, the corresponding light distribution scheme is used to collect the actual image of the workpiece to be measured; the described The actual image is compared with the corresponding standard image of the standard workpiece to generate a comparison result. The device uses the method. The invention can ensure the acquisition efficiency of the actual image, as well as the 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 capable of automatic light distribution and a comparison device. Background technique [0002] In the factory process production process, it is difficult to meet the actual needs only by manual inspection of product quality. Now the 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 embedded system integration technology for visual image acquisition, visual image processing and control. [0003] The above-mentioned embedded system is a combination of machine vision system and other sensor technologies, and its advantage is to solve the limitations of a single vision system. However, due to its high level of integration, when faced with changes in the measurement and control object (product) and the lig...
