Problems solved by technology
Nowadays, the conversion of the shooting angle by the 3D scanner is realized by changing the relative position between the scanner and the scanned object (A), which is not only labor-intensive, but the moving speed is slow, and the relative coordinates change greatly, which is difficult to control and is not conducive to shooting The balance of the image increases the difficulty of splicing
