The task:
OTTO Vision Technology GmbH builds image processing systems (measuring stations / measuring machines)
for quality checks, e.g. in the glass-processing, conductor board, furniture or swivel
and punching parts industry. E.g. different types of structures and their reference positions
are recorded on camera-equipped measuring tables or multi-camera positioning systems.
They are visualized in test jobs on the basis of camera images, bitmaps or CAD plans.
These test processes normally used to be created by Otto for its customers.
The task was to unify the previously individual creation of test jobs and to thus make
them flexible so that any desired test processes can be "constructed" with one tool.
Together with ORISA and based on liveLOOK a test job designer was developed that is
part of the VisionNetwork software package. Today Otto ships this designer to its
customers to enable them to create test jobs by themselves.
The solution:
The structure of a test job is stored in a tree structure. All measurements and
the process sequence (image position, construction) between them are defined in it.
Under the measurements are the details of the measuring processes. These are e.g. exact
positioning, detecting contours or edges, determining diameters, the structure of
geometric constructions, etc. The measurement accuracy can be defined from 1 µm.
Such a test job can be processed automatically or by the users themselves (by mouse click).
With the help of these test jobs measurements can be carried out on samples or
complete productions at the end of a production process to detect deviations
from the specifications and thus reduce rejects.
A server tool created by liveLOOK controls and manages the distribution of the
test jobs to the individual measuring stations.
Constructs pre-manufactured in a tree structure (structural parts of a test plan,
e.g. a construction to measure an angle) are available in a library and can be
drag-and-dropped during creation of a new test job.
