Angular filter for vehicle mounted cameras

摘要

A vision system for a vehicle includes a camera disposed at a windshield of a vehicle and having a field of view forward of the vehicle and through the windshield of the vehicle. A processor is operable to process image data captured by the camera. An angular filter is disposed at or near the windshield forward of the camera. The angular filter includes a substantially transparent film that limits reflection of light through an angular range that generally corresponds to the stray light that reflects off of the vehicle dashboard and would otherwise impinge a lens aperture of the camera.

1. A vision system for a vehicle, said vision system comprising:
a camera disposed at a windshield of a vehicle and having a field of view forward of the vehicle and through the windshield of the vehicle; wherein said camera comprises a lens; an angular filter disposed at or near the windshield forward of said camera, wherein said angular filter comprises a substantially transparent film that limits reflection of light through an angular range that generally corresponds to the stray light that reflects off of the vehicle and would otherwise impinge said lens of said camera; wherein said camera is electrically connected to circuitry established at a circuit board that is mounted generally at the windshield behind said camera; wherein said camera is electrically connected to said circuitry via a flexible electrical connector; and wherein said flexible electrical connector flexes to allow a viewing angle of said camera to be adjusted relative to a mounting angle of said circuit board.
