Tracking Tools distances are doubled?

Post by carpetfluff » Thu May 30, 2013 9:37 am

I just noticed that the distances reported by Tracking Tools are not in millimetres as I expected, but are instead doubled. For example, the real distances between markers on the calibration square (found using a tape measure) are as follows:

Origin to end of X axis: 300mm
Origin to end of Z axis: 400mm
End of X axis to end of Z axis (diagonally): 500mm

However, the coordinates of the markers reported by Tracking Tools result in the following measurements:

Origin to end of X axis: 600mm
Origin to end of Z axis: 800mm
End of X axis to end of Z axis (diagonally): 1000mm

These measurements are out by double the distance. Is there any reason for this? It seems like an arbitrary scaling that isn�t useful. I�m currently having to halve all of the measurements I obtain using Tracking Tools because of this.

Is there any way I can force Tracking Tools to return the true real-world distances?
