tklockau commented 1 year ago

Spin-off question from here: https://github.com/DSD-DBS/raillabel/issues/15#issue-1727678124

  1. What is the coordinate system for the GPS/IMU data
  2. What is the extrinsic calibration of the GPS/IMU data?
tklockau commented 1 year ago
  1. The IMU/GPS data included into the frame data is in the WGS84 coordinate system
  2. The GPS/IMU data has already been transformed to match the extrinsics of the lidar sensor

To add to that: Further specifications on the IMU/GPS data are in the Readme included in every sequence / ZIP file.
