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 frame

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

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

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

coordinate frame 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.
