Aiming at the problem of position and pose location of common workpiece, a workpiece location scheme using monocular vision platform and CAD model was proposed. In order to clarify the specific design of this scheme, this paper introduced the calibration method of monocular camera, the related technology of workpiece image recognition, designed the image preprocessing process of workpiece, and finally proposed a monocular vision localization algorithm based on CAD model. The experimental results showed that, compared with the location scheme based on priori relationship, the location scheme had higher accuracy and better flexibility, and could meet the needs of common workpiece location.
