Projector Calibration

We present a convenient calibration method for structured light projection system. The proposed clibration approach can realize 3D shape measurement without projector calibration, without system calibration, without precise linear z stage to be used, the relative position between camera and projector can be arbitrary, and the only involved device is a plane board. Experiment results validated that the accuracy of the proposed approach.

Experiment Verification

Optical 3D measurement systems are used in a lot of applications, for instance for quality control and reverse engineering. A structured light active optical 3D measurement method are very often based on projection sinusoidal fringe pattern on the object. The key element of such a shape measurement method is how to generate sinusoidal fringe pattern. The purpose of this paper is to review the method of generation sinusoidal fringe pattern and contrast the two chief method from the specific viewpoint based phase measurement profilmetry. Experiment verification of the performance of each generation method is provided and finally some suggestions on generation method for phase measurement profilometry applications is offered.
