SELF CALIBRATION OF EXTRINSIC CAMERA PARAMETERS FOR A VEHICLE CAMERA |
摘要 |
A system and method for calibrating a camera on a vehicle as the vehicle is being driven. The method includes identifying at least two feature points in at least two camera images from a vehicle that has moved between taking the images. The method then determines a camera translation direction between two camera positions. Following this, the method determines a ground plane in camera coordinates based on the corresponding feature points from the images and the camera translation direction. The method then determines a height of the camera above the ground and a rotation of the camera in vehicle coordinates. |
