结构光三维重构中拼接技术的应用

Application of registration technique in 3-D reconstruction

采用结构光投影法,通过摄像机标定技术得到被测物体表面的三维点云数据。根据重构目标采用旋转平台拼接或者标志点拼接,将不同视角下测量所得到的点云数据转换到同一坐标系下。实验证明,旋转台拼接技术能较好的实现小型物体的三维拼接,而标志点拼接技术则更适合运用在大型物体的拼接。

Using surface structure light projection technique, we can get 3-D point clouds of the object by camera calibration. We do research on 3-D registration technique using turntable or marked points on the object, these 3-D point clouds which are taken from different viewpoints are transformed into one coordinate. The experiment re- suits show that the turntable 3-D registration technique is suitable for small object, however the marked points 3-D registration technique for the big object.
