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.
