2019-05-20 02:28:20 -0500 | marked best answer | Raytracer in occupancy_grid_utils Dear Ros Users, I am trying to perform a raytracing from a pointcloud in my node. The aim is to have a result similar to the one provided by octomap_server, but in my node. I tried to occupancy_grid_utils package in ros_indigo, but it seems that raytracing is not well performed, in particular it seems that rays are "cutted" before the end point Do you have any suggestions? Thank you! |
