Calibration

ART Calibration
ART Calibration

If you need to calibrate the room (and you need to), this is how you do:

  • make sure the Tablebeamer is started in full screen mode
  • Calibrate te TableBeamer
  • place angle bracket so that bottom left corner of image is on middle of corner marker
  • hide all other markers, make sure cameras show "0"
  • In D-Track: Calibrate -> Room -> Continue
  • Wave around D-Track wand and make sure all cameras show "6" most of the time, this takes a couple seconds
  • Check results, select ok

You sometimes need to recalibrate bodies in D-Track, if you had to, this is how:

  • Settings -> Tracking -> number of 6d bodies: 6
  • Calibrate -> Body , due to body. Then wave the above bodies, one by one.

To add new bodies do the following:

  • In D-Track: Settings increase number of 6d bodies by one
  • Settings -> Advanced : Set body active
  • Settings -> Advanced -> body n Setting : Edit the name of the new body
  • Hide all other bodies
  • Place the new body on the table and make sure that all cameras can see all markerballs
  • Calibrate -> Body, due to body
  • Check results, select OK

Table Beamer (on atnavab16)

Table Beamer Table Beamer Remote
Table Beamer and its remote control

The TableBeamer is a Hitachi CP-X328.

Software

The X server on atnavab16 is configured to use two seperate screens

X-Display Screen
0.0 Monitor
0.1 Table Beamer

To start programms on the second display simply start them with the -display=:x.y commandline option. This does not work with the viewer, since no variables can be set in the ServiceDescription's startCommand. You will have to write a small shell script to change the display environment variable:

export DISPLAY=:0.1

Calibration

By convention adjust beamer image width to 1m on the projection table.
