Calibration files
The Project Tango tablet has two device-specific calibration files,
/persist/calibration.xml
and
/persist/rig.txt
.
These files contain very precise data describing the sensors and cameras for that particular device necessary for accurate
motion tracking and depth perception. If this file is not present, the device will use default factory calibration parameters
which are unlikely to work well (or at all).
