VEHICLE VISION SYSTEM WITH OBJECT DETECTION VIA TOP VIEW SUPERPOSITION
First Claim
1. A vehicle vision system comprising:
- a first camera disposed at a first side of a vehicle equipped with said vehicle vision system and having a first field of view exterior and sideward of the equipped vehicle;
a second camera disposed at the equipped vehicle and having a second exterior field of view exterior of the equipped vehicle;
wherein said first field of view of said first camera overlaps said second field of view of said second camera at a first overlapping region;
wherein said second camera and said first camera are operable to capture image data indicative of an object located at the first overlapping region;
wherein said first camera captures a first image data set of the object and said second camera captures a second image data set of the object;
wherein said first image data set and said second image data set both comprise a common sub-set of image data of the object;
wherein said first image data set further comprises a first sub-set of image data of the object and wherein said second image data set further comprises a second sub-set of image data of the object;
wherein both said first sub-set of image data of the object and said second sub-set of image data of the object differ from said common sub-set of image data of the object;
wherein said first sub-set of image data of the object differs from said second sub-set of image data of the object;
wherein an image processor processes said common sub-set of image data of the object, said first sub-set of image data of the object and said second sub-set of image data of the object;
wherein processing of said common sub-set of image data by said image processor differs from processing of said first sub-set of image data by said image processor and wherein processing of said common sub-set of image data by said image processor differs from processing of said second sub-set of image data by said image processor; and
wherein said image processor utilizes said common sub-set of image data of the object, said first sub-set of image data and said second sub-set of image data of the object to synthesize an image of the object for display on a display screen viewable in an interior cabin of the equipped vehicle by a driver normally operating the equipped vehicle.

Abstract
A vehicle vision system includes at least two cameras having exterior fields of view and an image processor that processes captured image data and compares image data in overlapping regions of fields of views of two or more adjacent or neighboring cameras at a vehicle (such as a corner region near a corner of the vehicle where a portion of the field of view of a side camera of the vehicle overlaps a portion of the field of view of a front or rear camera of the vehicle). The system processes a common data sub-set and different data sub-sets of image data captured by the cameras at the overlapping regions, and processes the common data sub-set differently from the other data sub-sets. The system may generate a synthesized image derived from the data sub-sets for displaying images at a display screen for viewing by the driver of the vehicle.
