Abstract
For creating a CG model from an existing 3D object, a laser scanner is commonly used for providing a geometry model and a digital camera for preparing photographs for texture mapping. It is important to have an accurate estimate of camera parameters in order to precisely align photographs on overlapping regions. The alignment based on silhouettes has been most frequently employed. In this paper we examine the combination of silhouettes and texture patterns for aligning textures. Initially an optimal strategy for camera position allocation is described. Then a new method of pattern matching is presented for more precise camera position estimation. Two toy objects were used to investigate the validity of our new method. It was found that our method could yield an alignment accuracy within one to two pixels(that corresponds to .5 to .6mm).
