The next best view planner is a real-time capable exploration path planner. From the current pose it expands a tree to find a next pose that gives a high exploration gain. This gain reflects the exploration of space that is not yet (sufficiently) known. As the vehicle proceeds on the path, the tree is recomputed, taking into account the new information from the sensor.
This README gives a short overview. For more information refer to the wiki.
To run the current version, compile the package nbvplanner, as well as additionally required packages. To get these:
git clone https://github.com/ethz-asl/nbvplanner.git
git clone https://github.com/ethz-asl/catkin_simple.git
git clone https://github.com/ethz-asl/eigen_catkin.git
git clone https://github.com/ethz-asl/volumetric_mapping.git
git clone https://github.com/ethz-asl/gflags_catkin.git
git clone https://github.com/ethz-asl/glog_catkin.git
git clone https://github.com/ethz-asl/minkindr.git
git clone https://github.com/ethz-asl/minkindr_ros.git
git clone https://github.com/ethz-asl/mav_comm.git
Moreover, make sure you have all the necessary octomap libraries:
apt-get install ros-<distro>-octomap-*
To be able to run the planner in the simulation environment, also clone the rotors repo:
git clone https://github.com/ethz-asl/rotors.git
For a simulation demo launch
roslaunch interface_nbvp_rotors flat_exploration.launch
Tested under ROS Indigo and Jade.
Further instructions for the visualization of the exploration progress, as well as more demo scenarios and descriptions of the parameters can be found in the wiki.
