| 摘要 |
The invention concerns a method for reconstructing the profile of a road (3) which consists in: moving above the road (2) three contact-free distance measuring sensors (Cav, Cmi, Car), aligned horizontally in the forward movin g direction and equidistant from one another, said sensors supplying signals representing their height above the road; measuring the distance covered by the sensors and subtracting twice the height (H2) measured by the meridian sensor (Cmi) from the sum of heights (H1, H3) of the end sensors (Cav, Car). The device comprises a horizontal beam equipped with three sensors, a distan ce measuring member and a calculator, the whole set being mounted on a support frame or vehicle.
