Abstract

Depth measurement and normal measurement have an advantage in different spatial frequency and are complementary in 3D shape measurement. However, conventional measurement of depth and normal is performed exclusively or in time-division manner and high-speed simultaneous measurement has not been achieved. In this paper, we propose a new optical system setup for high-speed simultaneous measurement of depth and normal with an active stereo method and a photometric stereo method. Furthermore, we propose a high-speed 3D shape reconstruction method using GPU, which combines complementary information obtained from the two measurements. We evaluated the throughput of the prototype system and the result shows high-speed depth and normal simultaneous measurement and 3D shape reconstruction are performed at 500fps.
