Abstract
The invention relates to a surface identification device for the movement of a vehicle at a distance from that surface, the device comprising a detection head, the head including at least one sensor of a property depending on the distance of the center of the head from the surface, each sensor covering a detection zone centered on a line of sight, an orientation system for the detection zone of each sensor, and a controller processing the signals from each sensor and controlling the system based on said signals. The controller estimates the direction of the perpendicular to the surface, and uses said system to rotate the line of sight of each sensor in a separate direction by a reorientation angle of the direction of said perpendicular.
