Hyperspectral imaging allows to identify chemical properties
of materials and to analyse thus differences in the materials. Objects leave a
unique „fingerprint” with their highly complex spectral information. However,
hyperspectral camera technology has not yet been widely applied in the
industrial environment. Standards for interfacing are missing, application work
has to be done by scientific-motivated methodology, elaborate correction effort
of cameras disorder has to be considered. Furthermore, the scientific analysis
of hyperspectral data is the field of experts of the disciplines of
multivariate data processing and chemometrics as well as spectroscopy. – Quite
not typical disciplines of vision engineers.
Therefore Perception Park introduced its Chemical Colour
Imaging (CCI) technology. CCI encapsulates the technologies mentioned above and provides a
promising alternative suitable for vision tasks. The user deals with
spectroscopic information and problems transformed in a domain natural to him –
in the colour domain. Therefore, complex spectroscopic problems get solvable
based on the interpretation of image information – the user is able to learn by
his cognitive intelligence and generates application specific know-how. Since
all workflows are based on workflows known from vision, hyperspectral cameras
based on CCI are applicable like standard vision cameras and allow solutions to
industrial challenges that were not thinkable in the past.
Spectral technology come along with a couple of
hundred data points per object pixel. As a consequence, this results in a
deluge of data to be processed in real-time. Industrial bulk sorting e.g.
requires object decisions within a few milliseconds.
Our customers mainly work in the fields of pharmaceutical processing and food processing.
