针对在光栅投影轮廓测量术中系统标定可操作性不强、精度不高的问题进行了全面的分析 ,在此基础上提出一种新的系统结构 ,并推导了物相关系。由于去掉了传统结构的平行和垂直两个约束条件 ,测量系统中摄像机和投影装置可以采取任意相对位置 ,操作十分灵活。对新系统提出了方便实用的标定方法 ,在其中引入了摄像机定标技术。应用该测量系统和标定技术进行实例检测 ,测量结果证明 :与传统方法相比 ,可操作性和检测精度得到了提高 Aiming at the problems of poor operability and low precision of system calibration in RSP, a new system structure is proposed and the phase relation is deduced. Due to the elimination of the parallel and vertical restraints of the traditional structure, the camera and the projection device in the measurement system can take any relative position and the operation is very flexible. The new system proposed a convenient and practical calibration method, in which camera calibration technology was introduced. Application of the measurement system and calibration technology for instance detection, measurement results show that: compared with the traditional method, the operability and detection accuracy has been improved
