Abstract (en)

[origin: WO0047511A1] The invention provides for a method of detecting objects in an area, the method including obtaining one or more images of the area, using an edge detection technique in such a way as to highlight substantially dominant linear features in the image(s), and determining if any dominant linear features intersect linear features defining the area. The method may also include detecting parallax in at least two images, the parallax being produced by the presence of 3-dimensional objects in the area.
