Research direction
Reproduce the NumPy coordinate transformation using the vehicle, ego, and sensor translation and rotation arrays shown in the issue. Compare the intermediate and final values with the dataset result, then document or correct the transformation so it matches [-19.02, -48.93, -1.20].
