360 degrees Three-Dimensional measurement using five measuring systems

Abstract

Recent years, the spread of devices to output Three-Dimension information are progressing. Researches about Three-Dimensional measurement have been actively carried out as a part of it. In general, when using the active stereo method, distance calibration is needed to associate the distance value to the pattern which the projector exposes. In addition, it is possible to extend the field of view by using multiple cameras, but a transformation matrix is needed to synthesize, due to the difference in the camera coordinate system. In this study, we propose a method to perform the distance calibration and the calculation of the transformation matrix at the same time, and then performed a 360degrees Tree-Dimensional measurement using the proposed method.
