Abstract

The invention discloses a product quality detection system and method based on opencv. The system comprises a conveying belt module, an opencv image acquisition module, an opencv image processing module and a manipulator module, the first output end of the opencv image acquisition module is connected with the first input end of the manipulator module; the second output end of the opencv image acquisition module is connected with the input end of the opencv image processing module; the output end of the opencv image processing module is connected with the second input end of the mechanical armmodule, the output end of the mechanical arm module is connected with the input end of the conveying belt module, and the output end of the conveying belt module is connected with the input end of theopencv image collecting module. The system has the advantages that image acquisition is carried out on products to be detected, histograms of the products to be detected and the products to be detected and normalization related parameters of the histograms are preliminarily calculated, and the purpose of preliminarily screening unqualified products is achieved; and then, the feature values of thetwo characteristic points are further calculated, so that the purpose of further screening unqualified products is achieved.

Description

technical field [0001] The invention relates to the technical field of product quality detection, in particular to an opencv-based product quality detection system and detection method. Background technique [0002] The quality of industrial products is related to the health and survival of human beings, and affects the development of society and economy. Carrying out quality inspection is an important basic work to understand and master the quality changes of industrial products, find problems in time, and strengthen quality management. Industrial product quality testing refers to the use of certain testing methods to measure the quality level of industrial products and the main factors affecting product quality in industrial production activities, and then compare the results of the measurement with the specified quality standards, so as to make a test of the test objects. The behavior of making a qualified or unqualified judgment and taking necessary adjustment, supervisi...
