Requirements for mounting the axle counting components
The LMS Axle 2D LiDAR sensor must be positioned so that it is able to record the entire
flank of the vehicle and, in particular, the entire axle area. Consequently, it must be
mounted at the side of the lane.
•
The area between the LMS Axle and the vehicle must be free from any optical
obstacles. Please note that items such as guardrails or bushes should not restrict the
scanner’s view.
•
The LMS Axle must have a good view of the road surface. A good view means that it
must be able to detect as many measurement points on the ground as possible.
Requirements for optimum measurement results
The LMS Axle achieves optimum measurement results when as many measurement
points can be generated in the analysis area (shadow pattern, point patterns for wheels)
as possible. In order to obtain the minimum number of measurement points required,
a mounting position for the LMS Axle must be selected so that the distance between the
2D LiDAR sensor and the wheels is not too large and so that the laser beam’s angle of
incidence is not too steep.
The flatter the angle of incidence and the closer the 2D LiDAR sensor is to the lane, the
more measurement points will be generated.
