....realizations of omnidirectional vision systems that combine a mirror and a lens and have a unique effective focal point. Building on the results of [6] we show in [8] that the image (x, y) of a 3D point q = X, Y, Z) obtained by a calibrated central panoramic camera with parameter # [0, 1] can be modeled as a projection onto the surface z = f # (x, y) # 1 # (x 1 # 1 (1 ) x (1) followed by orthographic projection onto the XY plane, as illustrated in Fig. 2. The composition of these two projections gives y . 2) When the camera ....
....on r, namely r min r max . Furthermore, the control law (11) is the gradient of a potential function V (r, #) k 2 (# , 15) which points transversely away from the safety boundary, and has a unique minimum at (r d , # d ) assuming r d r min ) Following Cowan et al. [1], one can modify V (r, #) to yield a proper navigation function whose associated controller guarantees collision avoidance. IV. EXPERIMENTAL RESULTS We tested our segmentation algorithm in a real sequence. Fig. 1(a) shows one out of 200 frames taken by a paracatadioptric camera (# = 1) observing ....
