摘要：We introduce a multiple-viewpoint 3-D measurement system that is suitable for acquiring high-speed and high-accuracy 3-D model model movie in real-time. The present system consists of multiple range finders, and each one consists of a camera and projector. We use a high-speed 3-D image sensor as a camera and used the range finders to measure various target objects from multiple viewpoints in a time-division manner. We then carried out a general linear calibration and evaluated the range accuracy. We demonstrated acquisition speeds of up to 10.6 range-maps/s for two cameras and 6.1 range-maps/s for three cameras in real-time. Our system is suitable for high-accuracy 3-D model acquisition with, at 1200 mm, an error to distance of less than 0.2 %. We show the applicability of the present system for when a strong light source is used. The present system is suitable for complete 3-D model acquisition since the detected areas of the overlap in multiple-viewpoint 3-D range finding is small.
