Abstract
An obstacle detection device to be fitted to a mobile vehicle able to move parallel to a reference plane comprises: at least two emitters of electromagnetic beams which are able to form two virtual planes in two different directions that are able to intersect one another and intersect a potential obstacle, at least one image sensor able to produce an image of the intersection of the virtual planes and of the potential obstacle, an image analysis means able to determine the presence of an obstacle, configured to compare the image with a reference image. A detection method employing such a device is also provided.
