It is very important to guarantee the quality of the industrial products by means of visual inspection. In order to reduce the soldering defect of terminal deformation and terminal burr in the manufacturing process, this paper proposes a 3D visual inspection system based on a stereo vision with single camera.<br>It is technically noted that the base line of this single camera stereo was precisely calibrated by the image processing procedure. Also to extraction of the measuring point coordinates for computing disparity, the error is reduced with original algorithm. Comparing its performance with that of human inspection using industrial microscope, the proposed 3D inspection could be an alternative both in precision and in processing cost. Since the practical specification in 3D precision is less than 0.02 mm and the experimental performance was around the same, it was demonstrated by the proposed system that the soldering defect with terminal deformation and terminal burr in inspection, especially in 3D inspection, was decreased.<br>In order to realize the inline inspection, 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.
