VEHICULAR IMAGING SYSTEM
First Claim
1. A vehicular imaging system comprising:
- an imaging device;
said imaging device comprising a plurality of photosensor elements;
said imaging device mounted at a vehicle and having a field of view exterior of said vehicle;
said imaging device capturing image data of a scene within said field of view;
a control receiving said image data;
said control also receiving, via a communication bus of said vehicle, at least one of (i) vehicle pitch information, (ii) vehicle yaw information and (iii) vehicle steering information;
said control detecting two substantially straight and converging road features along the road said vehicle is travelling;
said control determining a point of intersection where said two substantially straight and converging road features would converge;
said control automatically correcting for misalignment of said imaging device mounted at said vehicle; and
wherein said automatic correction for misalignment of said imaging device mounted at said vehicle comprises, at least in part, said determination by said control of said point of intersection.

Abstract
A vehicular imaging system comprises an imaging device having a plurality of photosensor elements. The imaging device captures image data of a scene exterior of the vehicle within its field of view. Image data captured by the imaging device is provided to a control. The control also receives via a communication bus at least one of vehicle pitch information, vehicle yaw information and vehicle steering information. The control detects two substantially straight and converging road features along the road the vehicle is travelling and determines a point of intersection where they would converge using, at least in part, the received vehicle information and the control automatically corrects for misalignment of the imaging device mounted at the vehicle.
