Measurement method for determining the position of an aircraft or motor vehicle relative to the side of a runway or road from an image obtained using a camera that includes at least one edge of the runway or road

摘要

Measurement method for use with aircraft and vehicles in which a camera images a plane with two border lines (2a, 2b) that represent the sides of a road or runway. The distance of the camera relative to the edge of the road or runway is determined from an equation linking its known height, the distance to road or runway edge and the angle (delta ) formed by the intersection of the road or runway edge and a line through its center at infinity, or the horizon.
