@MohamedAboushnief @ghimiredhikura hi, I'm new to lidar field. Can you help me out in understanding the ouster lidar output and how it is different from velodyne lidar output. Also the lidar format and if possible can you send me the sample data of Ouster Lidar. And were u able to resolve the issues

Hi
I have face the same error. Is there any advise?
