Hi,
Instead of the OS-64 we were testing last year, now we are dealing with the newest 128 Beam Ouster LiDAR, there are a lot of new features such as the json files were replaced by some txt files ended with .calib, I can parse the "beam_altitude_angles" and "beam_azimuth_angles" as before with a little efforts, but they also included something new which I'm not sure whether needed for points extraction:
