Vehicle Navigation Methods, Systems and Computer Program Products

摘要

Vehicle navigation methods, systems and computer program products are provided that create a composite video image of a scene from video images of the scene generated by a plurality of video image sensors. The video image from each image sensor includes a respective array of pixels. The composite video image is created by selecting for a composite image pixel at a given position in an array of composite image pixels a pixel at the given position from one of the respective pixel arrays having the highest signal level or highest signal-to-noise ratio. The selecting is repeatedly performed for a plurality of given positions in the array of composite image pixels. The composite video image can be displayed via a display, such as a head-up display utilized in a vehicle.
