Method and system of self-determination of the values of parameters intrinsic and ω extrinsic of a camera mounted at the edge of a merck sharp amp; dohme chaussee.

摘要

A method for determining values of the intrinsic and extrinsic parameters of a camera placed at the edge of a roadway, wherein the method includes: a step of detecting a vehicle passing in front of the camera; a step of determining, from at least one 2D image taken by the camera of the vehicle detected and at least one predetermined 3D vehicle model, the intrinsic and extrinsic parameters of the camera with respect to the reference frame of the predetermined 3D vehicle model or models so that a projection of said or one of said predetermined 3D vehicle models corresponds to said or one of the 2D images actually taken by said camera. A method for determining at least one physical quantity related to the positioning of said camera with respect to said roadway. It concerns systems designed to implement methods. Finally, it concerns computer programs for implementing said methods.
