Camera distortion during calibration

When I perform a 3 point wand calibration with 4xV120:SLIM cameras and 3.5mm wide lenses I get weird shapes. Using the default settings I get: http://www.crossproduct.com.au/auto.jpg If I change the lense from auto to 3.5mm I get better results: http://www.crossproduct.com.au/wide.jpg but still look...

Re: Converting Global to Local Orientation.

Have decided I'm going to get the points directly and make trackables in my own code. That way I will have more control over the orientation.

We are still having trouble getting a working configuration. I tried this and got bad results: http://www.crossproduct.com.au/glasses.jpg This is what we are trying to achieve: - A room 4.8m x 2.4m - We want a wearer of the glasses to be 6 DOF trackable in the whole room - The user will typically be...
