Visual 3-D reconstruction and registration methods are gaining immense importance in many practical applications in everyday life. Unfortunately, the applicability of such techniques is often limited because the accuracy requirements of procedures are too high, or if seen the other way around, the reconstruction quality is too low. One possibility to improve this situation is active planning of camera movements such that the maximum reconstruction quality is assured. To adress this problem, we have developed a simple, easy to use approach that is directly inspired by geometric considerations.
