Width = max_Si (Xmax(Si) – Xmin(Si))
Fig. 17: Dimensioning operating principle – Width
To calculate the width of the vehicle, sections (
Si
) are generated from the 3D point cloud
(S). The width is calculated for each section from the 3D point cloud. The maximum
vehicle width is determined by considering the maximum width of all sections from the 3D
point cloud.
This calculation method makes it possible to compensate for errors in cases where
vehicles follow a slightly curved path through the measurement site instead of traveling in
a perfectly straight line.
With the default calculation method, all the attachments on the vehicle (e.g., roof antenna
and side rearview mirrors) are included when calculating the dimensions. If country-specific
regulations stipulate that the vehicle dimensions must be calculated without including the
antenna or side rearview mirrors, the calculation method can be adapted accordingly.
For instance, the system can be configured so that the maximum width is only measured
as of a defined distance on the Z-axis, thereby excluding the side rearview mirrors from
the calculation.
