7. HARDWARE SETUP
supports the USB3 Vision protocol, making it compatible to all cameras that
correctly adhere to this standard. However, we recommend choosing a camera
model for which compatibility has successfully been tested. Camera models
with known compatibility are:
•
Nerian Karmin2 stereo camera
•
Basler dart
•
Basler ace
•
FLIR Blacky
•
FLIR Chameleon3
•
FLIR Flea3
•
FLIR Grashopper3
•
SVS-Vistek EXO
•
The Imaging Source DMK
•
Baumer CX series
•
Baumer EX series
7.4 Color Camera Considerations
While SceneScan is limited to grayscale cameras, SceneScan Pro also supports
color cameras. It should be noted that results from grasyscale cameras
typically outperform the results from color cameras at equal resolu-
tions.
When using color cameras, SceneScan can process an RGB or Bayer pat-
tern image. In the former case, the camera will need to perform Bayer pattern
demosaicing. When SceneScan performs demosaicing it will at the same time
downsample the image to half the original width and height. This is done in
order to minimize artifacts that originate from Bayer demosaicing. Hence it
is strongly recommended to let SceneScan perform the Bayer demo-
saicing, unless the full sensor resolution is required.
7.5 Camera Setup
Both cameras must have an exactly parallel viewing direction. They must be
mounted on a plane with a displacement that is perpendicular to the cameras'
optical axes. Furthermore, both cameras must be equipped with lenses that
have identical focal lengths. Because for most lenses adjusting the focus
also slightly aects the focal length (known as lens breathing), the
