Abstract
A vision system for a vehicle includes a camera configured to generate one of distorted and undistorted images. An alignment system is configured to generate a region of interest (ROI) for the camera, generate a bird's eye view (BEV) homography to convert undistorted points in the ROI to BEV points, generate a BEV image based on the one of distorted and undistorted images and one of the BEV homography and an updated BEV homography, adaptively update the BEV homography to generate the updated BEV homography, detect current locations of features in the BEV image, predict future locations of the features for a next BEV image, compare the current locations of the features in the BEV image with prior predicted locations, and convert the BEV points in the BEV image to an undistorted points in a perspective undistorted image using an inverse of the updated BEV homography.
