Abstract: A method for generating a surround view (SV) image for display in a view port of an SV processing system is provided that includes capturing, by at least one processor, corresponding images of video streams from each camera of a plurality of cameras and generating, by the at least one processor, the SV image using ray tracing for lens remapping to identify coordinates of pixels in the images corresponding to pixels in the SV image.

Abstract: Described examples include an integrated circuit having a point identifier configured to receive a stream of input frames and to identify point pairs on objects in the input frames. A ground plane converter transposes a position of the point pairs to a ground plane, the ground plane having a fixed relationship in at least one dimension relative to a source of the input frames. A motion estimator estimates a motion of the source of the input frames by comparing a plurality of point pairs between at least two input frames as transposed to the ground plane, in which the motion estimator compares a motion estimate determined by the plurality of point pairs and determines a refined motion estimate based on the plurality of point pairs excluding outliers from the plurality of point pairs.
