| Abstract: | Traditional ways to model complex free form shape are tedious and expe nsive. A new approach is put forward to settle the problem only using a pen and a still camera. At first, a pen is used to mark curves net on the surface of the object, then images are taken through a still digital camera and conveyed to a computer. After image processing, the curves nets between two adjacent images a re matched, and a new formulation of cameras' displacements and 3D positions is obtained through a optimal iteration algorithm. Examples experimenting on a sta tue are given, and the result is satisfied. |
