how to get 3D pointcloud from 2D Laserscan without robot simulation
All I have is a 2D Laser Scanner and a PC. I am able to get the 2D live data of the scanner in RVIZ. I want to make 3D representation by moving scanner. I have used laser_assembler library to make PointCloud of LaserScans. Now, i am getting the PointCloud in a single plane. I have searched and found that we need to transform scans before assembling. I am not understanding, how to do this. Can anybody please help.
