Vision system for vehicle
First Claim
1. A vision system for a vehicle, said vision system comprising:
- an imaging sensor disposed at a vehicle equipped with said vision system, wherein said imaging sensor comprises a plurality of photo-sensing pixels, and wherein said imaging sensor has a field of view exteriorly of the equipped vehicle, and wherein said imaging sensor is operable to capture an image data set representative of a scene occurring exteriorly of the equipped vehicle and in the exterior field of view of said imaging sensor;
a processor for processing said captured image data set via an edge detection algorithm;
wherein said edge detection algorithm is applied to a reduced image data set of said captured image data set to detect edges of objects present exteriorly of the equipped vehicle and within a target zone within the exterior field of view of said imaging sensor;
wherein said reduced data set is processed more than other image data of said captured image data set in order to detect objects present exteriorly of the equipped vehicle and within said target zone; and
wherein said target zone encompasses a geographic area of the exterior scene where an object of interest to the driver of the equipped vehicle is realistically expected to be present.

Abstract
A vision system for a vehicle includes an imaging sensor operable to capture an image data set representative of a scene occurring in the exterior field of view of the imaging sensor. A processor processes the captured image data set via an edge detection algorithm, which is applied to a reduced image data set of the captured image data set to detect edges of objects present exteriorly of the equipped vehicle and within a target zone within the exterior field of view of the imaging sensor. The reduced data set is processed more than other image data of the captured image data set in order to detect objects present exteriorly of the equipped vehicle and within the target zone. The target zone encompasses a geographic area of the exterior scene where an object of interest to the driver of the equipped vehicle is realistically expected to be present.
