Blogger fixes digital twin calibration with real OS0 lidar data and reflects on the process

Reddit user /u/No_Quail6685 shared the process of updating their office "robot dojo" digital twin with real Ouster OS0 lidar data. The new scan was first registered to the existing room map, after which the camera-LiDAR calibration required three iterations to align—the first approach's calibration result was offset by about 0.5 meters and 0.4 meters too high. The author also fitted a human gait trajectory based on a walking recording of about 13 meters. The author notes: the sensor collection is real, but the playback shown is recorded content, and the walking of the robot and generated avatar is simulated; the gait fitting residual is only an internal model check metric, not an accuracy independently verified by motion capture, and the gait model also comes only from a single recording.
