Available Models
Karmin3 is available in two different baseline distances: 10 cm and 25 cm. The
10 cm model is intended for close-range measurements, while the 25 cm model
is intended for long-range measurements. The covered measurement range also
depends on the selected lenses and on the processed disparity range, which is
the image overlap range that is searched during image processing.
Both baseline distances are available with either monochrome or color im-
age sensors. When used in combination with SceneScan, the monochrome
versions can achieve higher image resolutions and frame rates.
Using the
monochrome models is hence recommended if color information is not im-
portant for subsequent processing.
When using identical lenses and a constant disparity range, the 10 cm
models will have a lower minimum depth when compared to the 25 cm mod-
els. The depth error increases approximately quadratically with the measured
depth, starting at the minimum depth. Hence the 25 cm models will have a
lower depth error for all points that fall within its measurement range. If the
minimum depth of the 25 cm models is sufficient, then these models should be
preferred over the 10 cm models. Detailed characteristics, including the mini-
mum depth, are available on the Karmin3 product page
for the most common
configurations.
