Abstract: Utilizing computer to draw a caricaturing portrait is a front field of machine vision. In a digital photo that be shot by CCD, for obtaining some lines that can exhibit image with caricature feature and draw these lines by robot, a appropriate image processing algorithm should be involved. The algorithm should include face recognition and extracting feature of face. Obviously, the caricature should be generated according to some feature of face. Finally, after vectoring these represent lines, an Auto-Portrait robot will be controlled to draw cartoon portrait on a paper. This paper discuss proposed method for portrait and caricature, comment at existing system of Auto-Portrait robot. Further, future prospect of development and target is presented.

Key words: Auto-Portrait Robot, caricaturing, vector, planning trajectory
