手持式结构光对物体三维测量的方法研究

A Approach for Handheld Structured Light 3D Measurement to Objects

结构光三维测量方法广泛地应用在许多领域。在传统的测量方法中,利用固定的摄像机和激光器对物体进行测量,因此不够灵活方便。本文提出了一种无机械传动装置的手持式结构光对物体进行测量的方法。在本方法中,应用视频记录测量物体的全过程,因此对物体进行测量会更加方便。仅需要一个激光器和和一个摄像机就能够完成对物体的测量,因此测量系统的成本较低。文章通过对该方法的理论分析和实验研究,证明了利用该方法实现物体表面三维测量的可行性。

The approach for structure light 3D measurement is widely used in many fiehls. Objects are measured by immobile cameras and lasers in some traditional methods, so it isn＇t portable and flexible , This paper proposes a handhehl structured light measurement approach without mechanically-driven device for measuring objects. The approach of recording with video is used in this system. So it is convenient to he used for measuring objects. A laser and a camera are only used to complete measurement to objects. So the measurement system cost is lower. Through theoretical analysis and experimental results verify that the approach is feasible to complele 3D measurement to object surface.
