Paper Abstract

In this study, we develop a real-time, structured light 3D scanner that can output 3D video of 512×512 pixels at 500 fps using a GPU-based, high-speed vision system synchronized with a high-speed DLP projector. Our 3D scanner projects eight pairs of positive and negative image patterns with 8-bit gray code on the measurement objects at 1000 fps. Synchronized with the high-speed vision platform, these images are simultaneously captured at 1000 fps and processed in real time for 3D image generation at 500 fps by introducing parallel pixel processing on a NVIDIA Tesla 1060 GPU board. Several experiments are performed for high-speed 3D objects that undergo sudden 3D shape deformation.
