Abstract

It is very important to guarantee the quality of the industrial products by means of visual inspection. In order to reduce the human error in the manufacturing process, this paper proposes a 3D visual inspection system based on a stereo vision with single camera. It is technically noted that the base line of this single camera stereo was precisely calibrated by the image processing procedure of template matching. Comparing its performance with that of human inspection using OGP microscope, the proposed 3D inspection could be an alternative in precision and in processing cost. Since the practical specification in 3D precision is 0.02mm and the experimental performance was around the same, it was demonstrated by the proposed system that the human error in inspection, especially in 3D inspection, was decreased.<br>In order to realize the Total Production Cycle called HUTOP, this paper will suggest how the human inspection of the products could be modeled and be implemented by the computer system especially in manufacturing process.
