[ros-users] camera1394 and swissranger

[Patrick Beeson]

The swissranger is calibrated at the factory.  They do not provide the 
internal optical parameters they use when getting 3D points from 2D 
images.  If one wanted to rectify the 2D depth or intensity images, one 
could run a checkerboard calibration from the intensity image (I've done 
this).  I'm assuming this would be done at a higher level than the 
camera communication driver.   So, for now, camera parameters will need 
to be set to defaults.
