Fig. 63: Handling of dimensionally unstable objects
• Objects such as plastic bags or other unstable items are not suitable for MID-compliant
dimensioning (automatic LFT billing).
• The shape and size of these types of objects are not dimensionally stable. The
repeatability of the measurement result is therefore not guaranteed.
NOTE!
• After the manufacturer has placed the measurement system on the market,
the operating entity must ensure that dimensionally unstable, transparent or
reflective objects are excluded from billing operation.
• The possibility of multiple objects being present on a single conveyor element
must be excluded.
• The so-called operating entity’s responsibility applies!
▸
The risk of incorrect measurements can be avoided as follows:
• Process the objects in a separate package stream that bypasses the LFT measure-
ment.
• Use additional bar codes to identify dimensionally unstable objects and to tag the
measurement as a non-LFT compliant measurement.
• Use a classification system for dimensionally unstable objects (e.g. Deep Learning) and
tag the measurement results with a flag to indicate invalid measurement conditions.
