摘要：
A feature quantity type whole-space tabulation method (F-WSTM) was proposed by authors to make 3D shape measurement devices robust for vibrating. This method makes possible a camera calibration-free 3D shape measurement. Three phase information obtained with three projectors are used to obtain 3D coordinates without any camera parameters. That is, change of lens position does not cause the systematic error. In this method, focusing, zooming, pan and tilt are available anytime. In this paper, a prototype of a 3D shape measurement device using the F-WSTM was developed. The evaluation of the device was performed with an experiment of a shape measurement of a step object.
