Sparse optical flow calculated using the evolved operator. The algorithm for visual control of a mobile robot which was developed during the previous year was extended. Now the translatory velocity of the robot is also controlled. The algorithm extracts interesting points of the image sequence and calculates sparse optical flow induced by the translatory motion of the camera. Status information of the robot is used to compensate for the rotatory motion of the camera.
Translatory velocity is controlled such that the perceived optical flow remains constant.
