Files description:
-(camera_intrinsics) - intrinsic parameters for the cameras.
-(*_extrinsic_calibration.json) - extrinsic transformations between relevant referentials (rotations are in rads and translations in meters).
-(gait_depth_registered) - folder containing depth frames for gait camera, each file contains its index and timestamp(the data is saved as uint16 where values correspond to depth in mm).
-(posture_depth_registered) - folder containing depth frames for posture camera, each file contains its index and timestamp(the data is saved as uint16 where values correspond to depth in mm).
-(*_csv) - folder containing complete xsens data obtained from xsens .xlsx export method, and whose sheets were then extracted as individual .csv files (rotation units in degrees and position units in meters)
-(*.c3d) - xsens 3D position data exported as .c3d file(units in mm).
-(sync_*.stamp) - timestamp for the xsens hardware trigger.
