1. A vision system for a vehicle, said vision system comprising:

  • a plurality of imaging sensors disposed at the vehicle and having respective exterior fields of view, said imaging sensors capturing respective image data, wherein each of said imaging sensors includes a respective inclination sensor;

    at least one other inclination sensor disposed at the vehicle;

    a processing system that is operable to process outputs of said inclination sensors to determine an alignment or misalignment of said at least one imaging sensor at the vehicle;

    a display screen in the vehicle and viewable by the driver of the vehicle;

    wherein said vision system is operable to display images representative of said captured image data on said display screen;

    wherein said vision system is operable in a virtual top view vision mode, and wherein, when operating in said virtual top view vision mode, said processing system processes image data captured by said plurality of imaging sensors to at least one of combine and manipulate said image data, and wherein, when operating in said virtual top view vision mode, said vision system displays an exterior scene around the vehicle;

    wherein the displayed exterior scene is around the vehicle and has a first limited extension in a first dimension and a second limited extension in a second dimension, and wherein said second dimension is generally orthogonal to said first dimension, and wherein the result of a tangent steradian accuracy of said at least one inclination sensor divided by a longer one of said first and second limited extensions is greater than the highest resolution of at least one of said imaging sensors having its field of view along said longer limited extension'"'"'s path.
