A Monocular Ground Plane Estimation System [PDF]
Procedings of the British Machine Vision Conference 1991, 1991 This paper describes the design of a system for estimating the pose of a camera mounted on a vehicle which moves over a flat floor. The system has been designed to work in conjunction with an obstacle avoidance scheme. Measurements are derived from a sequence of images captured by a single camera rigidly mounted on the vehicle and looking at the floor,
