Chromatic aberration compensation for vehicle cameras

A vision system of a vehicle, said vision system comprising:

• a camera disposed at a rear portion of a vehicle and having a field of view exterior and rearward of the vehicle;
• wherein said camera comprises a lens and a two dimensional pixelated imaging array having a plurality of photosensing elements arranged in rows and columns of photosensing elements;
• wherein said lens comprises a single lens optic that focuses light at pixels of said imaging array;
• wherein said camera is operable to sense color via color filtering at photosensing elements of said pixelated imaging array;
• an image processor operable to process image data captured by said camera;
• wherein, responsive to image processing of captured image data, said image processor is operable to determine objects present in the field of view of said camera;
• wherein said vision system is operable to determine color aberration in the captured images;
• wherein said vision system determines color aberration based at least in part on parameters of portions of said lens that correlate to respective pixel portions of said imaging array;
• and
• wherein, responsive at least in part to processing of image data by said image processor, said vision system at least in part corrects the color aberration via correlation of respective pixels of said imaging array to parameters of respective portions of said lens focusing light at those pixels.

A vision system of a vehicle, said vision system comprising:

• a plurality of cameras disposed at a vehicle, each having a respective field of view exterior of the vehicle;
• wherein each of said cameras comprises a lens and a two dimensional pixelated imaging array having a plurality of photosensing elements arranged in rows and columns of photosensing elements;
• wherein said cameras are operable to sense color via color filtering at photosensing elements of said pixelated imaging arrays;
• an image processor operable to process image data captured by said cameras;
• wherein said vision system is operable to determine color aberration in the captured images;
• wherein said vision system determines color aberration based at least in part on parameters of portions of said lenses that correlate to respective pixel portions of the imaging arrays of the respective camera;
• wherein, responsive at least in part to processing of image data by said image processor, said vision system at least in part corrects the color aberration via correlation of respective pixels of said imaging arrays to parameters of respective portions of the lens focusing light at those pixels;
• and
• wherein said vision system determines color aberration based at least in part on distances of pixels of said imaging array from a center pixel that corresponds with a central axis of said lens.
