Paper Abstract

The 3D form measurement by using images is used in the various fields, for example a computer vision, a robot vision, CAD, and so on. In the application, the 3D measurement is often required to be fast. For the target which has the diffusion surface reflection characteristic, the active method is effective to a high-speed measurement. The active method includes the slit optical projection method, the method of the space encoding with a pattern projection, and the time series encoding pattern projection method, etc. However, there is a problem in a speed improvement as for each method. It is necessary for measurement to project several times at least. In this paper, the concentric circle is used as a projection pattern, and we can measure an object by projecting one time. It was confirmed in experiment that 3D measurement by using concentric circle is possible.
