Abstract
The disclosure relates to systems and methods for estimating or determining the motion of a vehicle and/or the distance to objects within view of a rear camera. A method for rear obstacle detection using structure from motion includes identifying image features in a first frame corresponding to features in a second frame, wherein the first frame and the second frame comprise adjacent image frames captured by a rear-facing camera of a vehicle. The method includes determining parameters for a non-planar motion model based on the image features. The method includes determining camera motion based on the parameters for the non-planar motion model.
