I am not sure it works that way. If you have a single scanner on the front or back of a vehicle then the "sweep" of the scanner is a line perpendicular to the direction of the vehicle. If you pass a, for instance junction box, then the laser will hit one side only so you have to assume the corner positions of the side scanned and then the rest of the box. With 2 scanners, such as the Reigl they are set at 45? degrees to the direction of the vehicle and 90? degrees to each other so neither scanner is scanning perpendicular to the direction of the vehicle. This means that passing the same junction box will scan 3 sides of it. This I assume is the advantage of having a two scanner system and not a higher scanning resolution.
