ABSTRACT
Machine vision technologies have been the focus of research in the fields of industrial robotics and automation for more than two decades now. Over the years, these technologies have revolutionized the manufacturing and inspection processes industries with the help of sophisticated vision-based robotics systems that can gage the location of a desired object in a 3-dimesional space, ascertain its orientation relative to its surroundings and perform the task accordingly. A basic machine vision system has a single stationary camera mounted over the workspace to enable image acquisition. With this form of active sensing, the position, orientation, identity and condition of each part can be obtained. This high level information can be used to plan the robotic motion, such as determining how to grasp a part and how to avoid collisions with obstacles.
The objective of this paper is to perform a pattern matching operation and blob analysis on an image processing inspector. An overhead CCD camera performs the task of image acquisition.
