摘要
Computer vision technology has been widely used in on-line inspection. In this paper, we present a computer vision system using structured light which provides us with an efficient solution for solder joint inspection. Our system uses a novel inspection technology to overcome some technology bottlenecks that traditional computer vision system experienced. We focus the SMD inspection process on the solder joint defects in this paper. We developed a surface shape estimation technique for solder joint using slant map. From this technique, a solder joint can be determined to be a good (concave), bad (convex), bridged solder joint, or solder joint with surplus solder, or lacking solder.
