Summary :

This paper presents a multi functional range finder employing dual imager core on a single chip. Each imager core has functionalities of 2-D imaging and 3-D capture using the light section method with combinations of the dual imager core. The presented chip achieves, 2-D imaging mode, 3-D capture mode with the conventional light-section method, high-speed 3-D capture mode with the stereo matching mode, and 2-D and 3-D simultaneous capture mode. We demonstrate 58 fps 2-D imaging with 8 bit gray scale, and 24.8 rangemaps/s 3-D range-finder with the maximum range error of 1.619 mm and the standard deviation of 0.385 mm at 700 mm.
