WIDE BASELINE OBJECT DETECTION STEREO SYSTEM
First Claim
Patent Images
1. A system that facilitates detecting an object in a surround-view image of a vehicle, comprising:
- a first camera that captures a first image of an object;
a second camera that captures a second image of the object;
a processor configured to;
generate a composite image by merging the first and second images;
analyze the composite image to detect one or more features indicative of the type of object in the composite image; and
generate a signal that indicates the presence of the object and location of the object relative to the vehicle.

Abstract
When detecting an object of interest, such as a bicyclist passing a truck, two downward looking cameras both capture images of the cyclist and detect the cyclist as a deviation from the flat ground plane. The ground plane is reconstructed using a homography (projection) matrix of each camera and compared. Where the camera images do not agree, the ground is not flat. The cyclist is located as the intersection of the rays extending to either end of the area of disagreement between the images.
