Abstract in different language: | In this paper a method is presented to extract photo textures from perspective views of a real object and to map these textures on a geometry model of the same. The main task to be solved here is to recover the parameters of the perspective projection, which determine the appearance of the textures in the reference image. We propose to use a differential alingment approach to determine these parameters in a very user friendly and intuitive manner. The method bases on the superposition of the reference photo and a perpective projection of the known object geometry in one image. By a few simple 2d mouse operations, the projection parameters are optimized such that the object geometry is aligned to the reference view. Once this is achieved, the photo textures can be extracted and mapped onto the geometry model automatically. |
