Hi~
First of all, thank you for your contribution.
When I read your paper, I didn't understand how to get formula 3 from formula 2. Can you tell me? thanks!
Oh there's a missing citation, but it's fairly standard. You may check the 5th page of this paper: https://journals.sagepub.com/doi/pdf/10.1177/027836499501400301
Thanks,It solves my doubts.
When I use my own sensor(VLP16 LIDAR) for calibration, the program prompts the following information:

What causes this problem? How to solve this problem? thank you!

have you solved this problem?I meet this problem too @772894624
I I didn't solve the problem. Because I use VLP16, I use other algorithms.@xzh313
