Abstract

A method for determining the orientation of a video camera attached to a vehicle relative to the vehicle coordinate system is disclosed. Using a video camera an incremental motion is measured based on the optical flow of the video stream. A linear motion component and a rotational motion component are determined. Based on a determined rotational angle the incremental motion is classified as linear or as rotational. The directional vector of the linear motion is used to estimate the longitudinal axis of the vehicle, and the rotational vector of the rotational motion is used for estimating the normal to the vehicle plane. Based thereon the orientation of the camera follows.
