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.
