ABSTRACT:
An image sequence is inputted200from the camera and vertical motion is estimated202.A windowed horizontal edge projection204is extracted from the inputted image sequence200and the horizontal edges are projected206. The horizontal edge projection206and the vertical motion estimation202are combined in a horizontal segmentation and tracking element208, and forwarded to an object parameter estimation element210where the object's distance and height are estimated. This data is combined in a fusion with radar detection element212. By correctly matching the overhead objects sensed by the radar and video camera, the proximity and relative speed can be ascertained. Once overhead objects have been identified they can be isolated and not considered for collision avoidance purposes.
