Dynamic height measurement for adaptive focused image capturing of large volume objects
The fast imaging of large volume objects on conveyor
belt systems for the distribution of packages or luggage
is not possible with simple camera arrangements. The
main problem is focusing the optical system at different
levels of objects. In general, special imaging systems
are required, which are often very costly. The speed
of image acquisition is limited primarily by the height
measurement and the mechanical focusing.
Currently we are working on a new method which al-
lows a significant performance increase compared to
previous approaches. In contrast to existing systems,
we avoid in our approach a mechanical focus. The focus
is to work purely electronically without moving parts
like mirrors and lenses, etc. The expected latency is
thus comparatively very low, if the height values are
calculated in real time. This is one of the challenges in
this topic.
The dynamic height measurement should not only pro-
vide a single value to focus the optical system. We
also want to capture the objects in their spatial surface
shape with a high resolution. This allows us to im-
plement features such as volume calculation, detection
of deformations, object registration and serialization.
