2023/02/20Background knowledge
As the eyes and brain of machines, machine vision plays an important role in the development of intelligence. With the development of modern industrial automation, machine vision inspection has been widely used in various inspection, measurement and part recognition. The common characteristics of such applications are continuous mass production and high requirements for appearance quality. It can improve the production capacity of qualified products and scrap inferior products at the early stage of the production process, thus reducing waste and saving costs. The 3D camera realizes the intellectualization, modernization and automation of industrial production by capturing and analyzing the image of the product line scan and outputting the results. With the development of technology and the improvement of detection demand, the application of 3D vision will be more and more extensive.
