High-Speed Visual Tracking of the Nearest Point of an Object Using 1,000-fps Adaptive Pattern Projection

A 1,000-jps camera-projector system in which projected patterns are adoptively controlled according to image processing results is described. Adaptive structured light projection enables fast and efficient 3-D information acquisition. The prototype system is applied to the tracking of the nearest point of an object, and experimental results show that the system successfully tracked an apex of a fast-moving large! object.
