针对大型物体三维形貌视觉测量,提出了一种新的视觉测量三维数据拼接方法。以一台高分辨率数码相

机作为全局测量设备,在测量过程中固定不动,并以数码相机坐标系作为全局坐标系。视觉传感器流动到不同位置对物

体各子区域进行测量,获得局部坐标系下的三维数据。以一平面靶标为中介将视觉传感器在各位置的局部坐标系统一

到全局坐标系下,从而将三维数据统一到全局坐标系下,完成三维拼接。-A new 3D data registration method for large surface vision measurement is proposed. A digital camera with high

resolution is used as the global measurement equipment , which is fixed at a certain position. The digital camera coordinate fr a me

is taken as the global coordinate fr a me. The vision sensor measures all sub2areas of the measured object in different positions to

acquire 3D data of the sub2areas in local coordinate fr a mes. The local coordinate fr a mes of the vision sensor in different positions

are unified into the global coordinate fr a me by a planar target as the intermediary. Then the 3D data are unified into the global

coordinate fr a me and 3D registration is completed. The proposed method need not stick marks on the measured object , so it is

suit to all the measured objects regardless of material.
