5. CONCLUSION 
It is presented a new smart approach to acquire the initial value 
of all profile of the object in this paper, which is only to 
compute the calibration parameters of CCD camera and the 
projector in every angle, but not to do the complicated 
coordinate conversion. In the whole process, the positions of the 
camera and the digital projector are both never removed. The 
untouched method which has high efficiency and strong 
automation is essential to merge the metrical data of all the 
model. And the experiments indicate that the proposed method 
plays an important role in the multi-view metrical data 
integration of the 3D measurement.
