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.
