Learning-aided 3D mapping

Learning-Aided 3D Mapping

Build Status

A suite of algorithms for learning-aided mapping. Includes implementations of Gaussian process regression and Bayesian generalized kernel inference for occupancy prediction using test-data octrees. A demonstration of the system can be found here: https://youtu.be/SRXLMALpU20

Overview

This implementation as it stands now is primarily intended to enable replication of these methods over a few datasets. In addition to the implementation of relevant learning algorithms and data structures, we provide two sets of range data (sim_structured and sim_unstructured) collected in Gazebo for demonstration. Parameters of the sensors and environments are set in the relevant yaml files contained in the config/datasets directory, while configuration of parameters for the mapping methods can be found in config/methods.

Getting Started

Dependencies

The current package runs with ROS Noetic, but for testing in ROS Kinetic and ROS Indigo, you can set the CMAKE flag in the CMAKELists file to c++11.

Octomap is a dependancy, which can be installed using the command below. Change distribution as necessary.

$ sudo apt-get install ros-noetic-octomap*

Building with catkin

The repository is set up to work with catkin, so to get started you can clone the repository into your catkin workspace src folder and compile with catkin_make:

my_catkin_workspace/src$ git clone https://github.com/RobustFieldAutonomyLab/la3dm.git
my_catkin_workspace/src$ cd ..
my_catkin_workspace$ catkin_make
my_catkin_workspace$ source ~/my_catkin_workspace/devel/setup.bash

Running the Demo

To run the demo on the sim_structured environment, simply run:

$ roslaunch la3dm la3dm_static.launch

which by default will run using the BGKOctoMap-LV method. If you want to try a different method or dataset, simply pass the name of the method or dataset as a parameter. For example, if you want to run GPOctoMap on the sim_unstructured map, you would run:

$ roslaunch la3dm la3dm_static.launch method:=gpoctomap dataset:=sim_unstructured
