摘要：
To solve the problems of system calibration in phase measuring profilometry (PMP), a new measurement model is proposed. In this model, the relation between phase and height is extended to the 3D space. And it is no longer necessary to arrange the system in parallel, while the camera and projector can be in arbitrary position. By virtue of the camera calibration technique, a convenient and practical calibration method is proposed. The experiments demonstrate that this calibration method is flexible and applicable to many shape measurement tasks. The calibration proceeding can be accomplished within 2 minutes and the system precision is improved.
