A fruit sorting and inspection system uses the Matrox Imaging Library to process
images of apples. Binarization and blob analysis separate the fruit from its
background and obtain dimensions like Feret diameters and elongation.

One of the key processes at Austria-based auto battery maker Banner GmbH’s finishing plant is the visual final inspection. Based on Cognex’s VisionPro software,
the image processing software OBI (Optical Battery Inspection) from Schmachtl GmbH coordinates the data from six industrial cameras and one
Cognex DataMan 100 ID reader. The OBI system inspects the batteries from five sides and verifies the position and completeness of the labels, various
battery dimensions, the presence of pole caps and grips, and the dimensions of the vents. The software also reads the label pinned directly onto the
plastic housing of the battery, which contains information about the battery type, manufacturing date and performance. Courtesy of Cognex.
achieve this state, however, the software
has had to undergo several stages of evolution so that the growing numbers of
cores (or threads) are not wasted.
Automated optical inspection systems –
as used in different manufacturing indus-
tries – do share common underlying re-
quirements, such as locating objects or
features, analyzing/measuring objects/
features, and reading/verifying ID marks,
said Pierantonio Boriero, product line
manager at Matrox Imaging in Dorval,
Quebec, Canada. Other systems have other
requirements, however. Medical imaging
systems, for example, differ substantially
in that their goal is to enhance visualiza-
tion to aid diagnoses.
