We introduce a visual motion segmentation method employing spherical geometry
for fisheye cameras and automoated driving. Three commonly used geometric
constraints in pin-hole imagery (the positive height, positive depth and
epipolar constraints) are reformulated to spherical coordinates, making them
invariant to specific camera configurations as long as the camera calibration
is known. A fourth constraint, known as the anti-parallel constraint, is added
to resolve motion-parallax ambiguity, to support the detection of moving
objects undergoing parallel or near-parallel motion with respect …
