• In a second step, the shadow patterns undergo a plausibility check. This means that
each shadowed area is checked to see whether there is a corresponding point pattern
for a wheel.
Every wheel detected is counted as one axle. Twin wheels count as one axle. Wheels on
a raised axle (at least 10 cm above the ground) will not be counted.

Calculating axle positions
The axle positions are determined on the basis of the point cloud starting from the front of
the vehicle.

Calculating vehicle height above the first axle
For the calculation of the vehicle height above the first axle, the profile cross-sections
and the 3D point cloud recorded by the LMS Axle are used to search for the existence
of an axle within the first 2 meters of the vehicle. The position of the first axle is used
to calculate the height of the vehicle in this area.
