Camera Rig Calibration #1

Open TheTrueCoder opened 3 years ago

TheTrueCoder commented 3 years ago

For calibrating the camera pose relative to the tracker, I plan on using the Mixed Reality software LIV. After running through the LIV calibration wizard, export the camera pose/offset file as Unity(Full). As of now, this is the only format that includes the essential transform offsets.

Then I set the Auto Rig parameters with the info from the file, making sure to convert from Unity coordinates to Unreal coordinates. Unity -> Unreal:

Y -> Z
Z -> Y
X -> X

The calibration includes a FOV value, but I am using the sensor size and focal length from this website to have a (hopefully) more accurate reconstruction.

Parameters

Focal length: 26.5 mm
Sensor width: 25.4 mm
