Calibration problem
Posted: Thu Feb 21, 2008 2:25 pm
I am a new user and I have 12 cameras set up on a trust
17ft x 13ft x 13 ft
I use 12 V100 cameras, 6 tripods, sync cables.
4 at the top corners, 4 at the corners about 4 ft from the ground
and 4 in the middle of the top beams.
in the middle of the area I used a tripod with the wand
initially to align the cameras
We then lay on our back holding up the wand and move the wand in circular springs moving across the floor
then go to our knees, the semi standing so the wand
is always over our head but never occluded by the body
I've collected frames at High and Slow and tried
500, 1000, 10000 points in the next step
However it constantly says
"only (0-15) points survived, not enough for selfcalibration"
and forces me to redo all the steps.
We tried about 10 times and cannot figure out what is going wrong.
Is the space too large?
Is there another method to do 12 cameras
