Reflector detection
Fig. 13: Restricted radius of action
Reducing the radius of action
You can configure the minimum and maximum radius using a software telegram from the
vehicle computer.
The example in fig. 15 shows a defined, restricted radius of action with the parameters
rmin = 500 mm and rmax = 15,000 mm in which the NAV245 detects five reflectors within
a 270° scanning area.
Suppressing sectors (sector muting)
In certain applications, it may be necessary to suppress individual angle segments (sectors)
within the 270° scanning area of the NAV245, e.g., if individual reflectors are partially
hidden by a raised load and therefore the middle of the reflectors cannot be determined
accurately. This can lead to reduced accuracy when determining the position.
The limits of the suppressed sectors are output in a mathematically positive direction as
angles in mdeg. Up to four sectors are possible.
