A vehicular imaging system comprises a single imaging sensor having a plurality of photosensor elements. The imaging sensor captures image data of a scene exterior of the vehicle within its field of view. Image data captured by the imaging sensor 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 sensor mounted at the vehicle.
