The invention relates to a device (10) for detecting obstacles intended for being provided on a mobile vehicle (11) parallel to a reference plane (12). According to the invention, the device (10) comprises: at least two emitters (14, 16, 19, 32, 34, 35) of an electromagnetic beam (15, 17, 20, 27, 30, 31) capable of forming two virtual planes (22, 23, 24, 26, 28, 29) in two separate directions that can intersect one another and a possible obstacle; at least one image sensor (5, 6, 7) capable of producing an image of the intersection of the virtual planes (22, 23, 24, 26, 28, 29) and of the possible obstacle; an image-analysis means capable of determining the presence of an obstacle, configured so as to compare the image with a reference image. The invention also relates to a detection method using such a device. |
