Algorithms of Automatic Image Measure System
In terms of the inspecting and measuring requirements of modern industrial products, i.e. high dimensional measuring precision and high inspecting and measuring speed, a contact-less and automatic image measuring system based on image measuring and inspecting technology is presented. Its components and working principle is also discussed. Measuring principles and algorithms of typical plane geometric figures are analyzed by taking the measurements of the line and circle geometric figures as an example. The recognition of geometric figures based on image feature parameters is presented. After the performance of several autofocus evaluating methods is compared, the algorithm of height measurement by visual automatic focusing is presented. The methods of measurement scale setup and the correction of raster reading error are introduced as well. Experimental results indicate that the system has advantages of non-contact, online, real time, higher precision and rapid speed, as well as strong anti-jamming and stabilization.
