结构光三维重构中标定方法的研究

On Calibration Method in a Three-Dimensional Reconstruction System Based on Structured Light Vision

针对结构光视觉的三维重构系统,分析研究摄像机标定方法,利用摄像机标定结果,把投影仪当作逆光路摄像机,对标定板上特征点进行坐标转换,从而快速、精确实现结构光三维重构系统的标定。实验证明,该方法简单容易实现,速度快,误差小于0.3像素。

As to a three - dimensional reconstruction system based on structured light vision, this paper makes an analysis of the camera calibration method. By taking the camera calibration result, using the projector as a back - lighted camera and extracting the feature points of calibration board for coordinate transfbrmation, the calibration was realized rapidly and accurately. The experiment result shows that the system can realize reconstruction easily with error smaller than 0.3px.
