Catadioptric imaging sensors provide 360° horizontal view which may beadvantageous for visual surveillance and motion detection in somerobotic applications. Larger object surfaces can be perceived in a wideangle of view supplied by such an omnidirectional camera. The durationof object appearance in the field of view is also longer. Theseproperties cause smooth variations of the image scenes and facilitatethe calculation of the optical flow. Using such a flow field allows todetect ego-motion and some other fundamental preliminaries of robotnavigation.In this paper, we review the motion detection algorithms, which may beappropriate for optical flow calculations on omnidirectional images.
