Camera positional information

Post by JeDi » Mon Oct 08, 2012 11:57 am

Hi,

We are doing experiments on positioning the six cameras we use for our specific setup, and want to save/report the position and rotation information (so the extrinsic parameters) of the cameras, so we can reproduce the setup later on.

Is this possible, using the Tracking Tools software, the SDK, or any of the streaming protocols?

Greetings,
Jeroen Dierckx

You can certainly do this through the Tracking Tools API. Calibrate, then load the calibration and use TT_CameraXPosition(), TT_CameraYPosition(), and TT_CameraZPosition() for position, and TT_CameraOrientationMatrix() for orientation.

Thanks a lot! I will use the SDK to save the information then. Is this information by any chance also available in the Tracking Tools GUI?

Those commands are specific to the TT_API, as the SDK has no concept of calibration.
