Forward looking sensor system
First Claim
1. A forward looking vision system for a vehicle, comprising:
- a forward looking sensor configured to obtain a two-dimensional image of a space in front of the vehicle;
a region identification element that divides the two-dimensional image into a plurality of regions, each region representing a portion of the space in front of the vehicle;
an image transform element that transforms the two-dimensional image to a three-dimensional coordinate system representing the space in front of the vehicle to calculate depth information for at least a portion of the image; and
a plurality of expect systems, each expert system having at least one associated region and each region having at least one associated expert system, that control respective vehicle functions according to data from their respective associated at least one associated regions and the calculated depth information.

Abstract
Systems and methods are provided for controlling a plurality of vehicle systems. A forward looking sensor (12) is configured to obtain a two-dimensional image of a space in front of the vehicle. A region identification element (14) divides the two-dimensional image into a plurality of regions. Each region represents a portion of the space forward of the vehicle. An image transform (16) transforms the two-dimensional image to a three-dimensional coordinate system representing the space in front of the vehicle to calculate depth information for at least a portion of the image. Each of a plurality of expert systems (18-20) have at least one associated region and control a vehicle system (22-24) according to data from their respective at least one associated region and the calculated depth information.
