Dynamic Projection Mapping using High-Precision and High-Speed Three Dimensional Measurement by Two Projectors Placed in Parallel

Abstract

In recent years, it is required to acquire three-dimensional information at high speed in various fields. In our laboratory, we proposed a structured light field as a fast three dimensional measurement method. In the structured light field method, distance information can be obtained at high speed in principle by using a projection system in which the pattern of the projected stripe changes according to the distance. Thus, the distance information can be derived from the projected pattern. By using two parallel projectors, it is possible to acquire three-dimensional information with higher precision than the previously proposed method. The effectiveness of the proposed method is confirmed from the projection experiment by the laser projector on the dynamic projection target.
