How to make 2d occupancy gridmap from 3d pointcloud

SFlyn1 — Tue, 24 Dec 2019 07:44:44 GMT

I am trying to do something very similar to - https://www.youtube.com/watch?v=LBMsWJJxLXQ

currently, i am considering every point above and below a certain distance from the camera origin to be an obstacle . Then use the x,z poistion of the obstacles to make a grid map where each entry in the x,z space is an obstacle.

Is there any better way to do this(WITHOUT ROS)?

I researched your question very carefully. The only solution I could find that did not seem to be dependent on ROS though was OctoMap.
