Each T-Pod utilizes a
dual digital CCD camera measurement system. The individual
cameras are surrounded by 900 LED’s to provide illumination
to facilitate measurement. The two cameras have a slightly
different viewing angle to the wheel. The integration of the
two images produces a spatial display. This principle is
similar to the way we can see in three dimensions.
Two-dimensionally perceived images, from each of our eyes,
are integrated in our brain to give a spatial impression.
Each of the T-Pods is equipped with its own computing
capability, evaluates the stereoscopic images and then
determines how the wheel is spatially positioned. This
spatial image of the rim is calculated in each T-Pod by 4
digital signal processors, for a total of 16 system digital
signal processors in the measurement system. The data is
then processed and displayed on the computer system display.
The integrated reference system, IRES called, allows placing
the t-pods free in front of the wheel of the car.
The
effective illumination of the rim is covered by a Beissbarth
developed program. It control the 1800 Infra Red LED, which
are working in invisible range, depending on the ambition
light and reflection of the measured rim. Again, a
Beissbarth own program is responsible for the recognition of
rim, irrespective of color, shape, size or cleanliness. With
the combination of these two programs all kind of rims can
be measured.
Sun light on the working bay does not disturb the
measurement procedure or the results.
