Abstract
A system and method for providing online calibration of a plurality of cameras in a surround-view camera system on a vehicle. The method provides consecutive images from each of the cameras in the surround-view system and identifies overlap image areas for adjacent cameras. The method identifies matching feature points in the overlap areas of the images and estimates camera parameters in world coordinates for each of the cameras. The method then estimates a vehicle pose of the vehicle in world coordinates and calculates the camera parameters in vehicle coordinates using the estimated camera parameters in the world coordinates and the estimated vehicle pose to provide the calibration.
