change the height/angle of the laser scan created from pointcloud
hi
I have used pointcloud-to-laserscan, and works fine. now the problem is that my lidar is at the top of my robot, and so laserscan has created at that level. Now I want to change this height/or angle,inorder to laser scan can detect the objects which situated infront of it. How can i change the angle or height of the laser scan?? thanks
