Abstract

Presently there is a growing demand for fast and precise 3D computer vision systems for a wide variety of industrial applications like reverse engineering, quality control and industrial gauging. One important aspect of any vision system is the data acquisition. If the principle of triangulation is used the correspondence problem is to be solved. The coded light approach offers a fast way to overcome this problem and to provide dense range data. In order to get high accuracy range images the system needs to be calibrated. In this paper, we compare two calibration techniques: polynomial depth calibration and photogrammetric calibration. We have carried out both methods independently. To obtain results about the accuracy in object space, we measured the surface of a plane- table.
