THE SURROUNDVIEW SYSTEM CAMERA AUTOMATIC CALIBRATION-ONLY EXTRINSIC PARAMETERS

摘要

A method for calibrating a camera system comprising a plurality of cameras having a predetermined intrinsic calibration, the cameras being provided on an object such as a vehicle and covering a surrounding perimeter of the object, comprising the steps of: positioning a set of markers spaced apart by known dimensions and located on a single plane in the surrounding perimeter of the object and in the field of view of a camera; then calculating extrinsic parameters of the camera from the respective set of markers for the camera; and repeating the steps for each of the other cameras of the plurality of cameras.
