Abstract
The application provides a method of calibrating a camera of a vehicle. The vehicle has a reference frame. The method comprises taking an image of a scene by the camera. The ground plane of the vehicle is then determined according to features of the image. An origin point of the vehicle reference frame is later defined as being located on the determined ground plane. A translation of a reference frame of the camera is afterward determined for aligning the camera reference frame with the vehicle reference frame.
