在过去的几年里，我们一直在开发利用数字条纹投影和相移技术进行高速三维形状测量的技术：开发了各种算法来提高相位计算速度，采用并行编程来进一步提高处理速度，并采用先进的硬件技术来提高坐标计算和三维几何绘制的速度。我们已经成功地以30帧/秒的速度，以每帧300 K点的速度同时实现了三维绝对形状的获取、重建和显示。本文介绍了我们开发的实时三维形状测量技术的原理，总结了该领域的最新进展，并讨论了进一步推进该技术的挑战。2009爱思唯尔有限公司版权所有。
Over the past few years, we have been developing techniques for high-speed 3D shape measurement using digital fringe projection and phase-shifting techniques: various algorithms have been developed to improve the phase computation speed, parallel programming has been employed to further increase the processing speed, and advanced hardware technologies have been adopted to boost the speed of coordinate calculations and 3D geometry rendering. We have successfully achieved simultaneous 3D absolute shape acquisition, reconstruction, and display at a speed of 30 frames/s with 300 K points per frame. This paper presents the principles of the real-time 3D shape measurement techniques that we developed, summarizes the most recent progresses that have been made in this field, and discusses the challenges for advancing this technology further.
