Thanks a lot for your work on this dataset. After reading your website and pdf doc, I have a question: Position ground truth can be checked by compare with the samples of leica/MRP122 system. How can I know/ensure the attitude ground truth are accurate ? Except for projecting virtual points, which is “quantitatively inaccurate”
