Abstract

SMT solder paste deposition quality can be quickly inspected by 3D machine vision based on structured light projection. Digital image acquisition unit designing is one of the most important parts of the inspection system. This paper described a new structure of image acquisition unit designed for solder paste 3D inspection including camera, lens and projector choices, setting and calibration. The image acquisition and calibration experimental results showed that the designed image acquisition unit could satisfy the 3D inspection precision demands.
