I was looking for a way to create an octomap tree from arbitrary mesh file. Well at first I tried to convert my data into PCL pointcloud and then convert them into an octomap tree. But the problem was, for instance when you a cuboid mesh, you only have 8 vertex, which gives you 8 point and the walls between …
In this tutorial, I explain the concept, probabilistic sensor fusion model and the sensor model used in Octomap library. related publication: OctoMap: An Efficient Probabilistic 3D Mapping Framework Based on Octrees 1)Octamap Volumetric Model 2)Probabilistic Sensor Fusion Model 3)Sensor Model for Laser Range Data
Here is an example of obtaining occupancy grid from sensory data of turtlebot robot. 1.First you need to install all dependencies for gazebo and turtlebot and octomap server:
|
1 |
sudo apt-get install ros-kinetic-gmapping ros-kinetic-turtlebot-gazebo ros-kinetic-turtlebot-simulator ros-kinetic-turtlebot-teleop |
2. Launch gazebo in a simulated environment:
|
1 |
roslaunch turtlebot_gazebo turtlebot_world.launch |
3.Launch RVIZ to view the published data
|
1 |
roslaunch turtlebot_rviz_launchers view_robot.launch |
3.Move your robot via keyboard:
|
1 |
roslaunch turtlebot_teleop keyboard_teleop.launch |
to learn how to move the robot with …
