无约束结构光三维测量系统方法研究

传统的结构光三维测量系统对摄像机和投影仪的摆放有严格的要求或者标定过程较为复杂。本文根据光平面的概念通过增加光平面的参考点和法向量参数,使摄像机和投影仪之间位置无约束并简化标定过程,对这一方案进行理论分析和研究,提出了这一方法在实现上的基本原理,并进行了实验验证。实验结果验证了理论分析的正确性和应用的可行性。

Research on 3D Measurement System with Non-restricted Structured Light

Traditionally the position between camera and projector is limited in the 3D measurement system based on structured light,or the process of system's calibration is very complicated.In order to overcome the drawbacks of the structured light system,this report makes use of the concept of stripe-light plane by increasing some parameters such as the principal points and normal vector of stripe-light plane during the calibration.The paper proves the feasibility of the theory and points out the notices in the realization.The experimental results prove the validity and feasibility of the approaches in theory and application.
