Abstract
A method of range image sensing by integration of active and passive methods using multiple spotlights is proposed. The active stereo method using multiple spotlights can sense fast and robustly, but its measurement is sparse. The passive stereo method using stereo camera realizes dense measurement, but it cannot sense fast. Using the information of active stereo sensing makes the measurement time of passive stereo sensing by a stereo camera shorter and makes its accuracy higher. This paper explains the improvement of the range image sensor that integrates active and passive methods using multiple spotlights and a stereo camera.
