Abstract
In recent years, improving and extending the capabilities of the three-dimensional (3D) imaging to fast-speed and high-accuracy performance has been a very active research topic. Although the latest advances may help provide real-time and high-resolution measurements, to simultaneously achieve high-accuracy performance is still a big challenge. In this paper, we describe a novel 3D shape measurement and 3D imaging system based on using the fringe projection technique. It employs a generalized system setup, an ultrafast multiple-frequency phase-unwrapping algorithm, a flexible system calibration method, a robust gamma correction technique, and a graphical-programming-unit-based (GPU-based) data processing scheme to achieve fast-speed, high-accuracy and fast-speed 3D shape measurement and 3D imaging performance. The real-time system can operate at a speed of 45 3D-frames/second with relative accuracy of 1/2,500 or at a reduced speed of 10 3D-frames/second with enhanced accuracy of 1/10,000.
