Abstract :
The problem of registration of perspectively deformed range images presented in this paper. The deformation correction is considered as a calibration correction of the correspondent cameras. An algorithm for an affine transformation compensation is presented. We focus on the registration of high dimensional human head range images. Our aim is to stitch the corrected surfaces in order to estimate of full head model. A modification of the ICP algorithm is described. The latter is aimed at estimating affine transformation.
