VEHICLE VISION SYSTEM WITH CAMERA VIEWING THROUGH WINDSHIELD

摘要

A vision system of a vehicle includes a camera disposed at a vehicle windshield and viewing through the windshield and exterior of the vehicle. A light-absorbing hiding layer is established at the windshield at an area at which the camera is disposed and includes an portion established therethrough, with the portion aligned with the camera such that the camera views through the windshield via the portion. The portion comprises a wider central region and narrower upper and lower regions. The wider central region of the portion provides a wide angle field of view of the camera at a region ahead of the vehicle and the narrower lower region of the portion reduces the field of view at regions near to and sidewards from the front of the vehicle. An image processor is operable to process image data captured by the camera for a machine vision function or driver assistance system.

主权项

1. A vision system of a vehicle, said vision system comprising:
a camera disposed at a windshield of a vehicle viewing through the windshield and exterior of the vehicle; a light-absorbing hiding layer established at part of the windshield at an area at which said camera is disposed; wherein said light-absorbing hiding layer has a light-transmitting portion established therethrough and wherein said light-transmitting portion is aligned with a lens and imager of said camera such that said camera views through the windshield via said light-transmitting portion; wherein said light-transmitting portion comprises a wider central region and narrower upper and lower regions, and wherein said wider central region of said light-transmitting portion provides a wide angle field of view through the windshield for said camera at a region ahead of the vehicle and wherein said narrower lower region of said light-transmitting portion reduces the field of view through the windshield for said camera at regions near to and sidewards from the front of the vehicle; and an image processor operable to process image data captured by said camera for at least one of (i) an object detection function, (ii) a lane marker detection function, (iii) an emergency braking function and (iv) a warning function.
