RTAB-Map in ROS 101 Python

Learn how to use the rtabmap_ros package for performing RGB-D SLAM

Course Overview

Description

RTAB-Map (Real-Time Appearance-Based Mapping) is an RGB-D SLAM approach based on a loop closure detector.

The loop closure detector uses a bag-of-words approach in order to determinate if a new image detected by an RGB-D sensor is from a new location or from a location that has been already visited.

Of course, this is a very summarized explanation. You will get more details on how this loop closure detector works inside this Course.

Learning Objectives

  • Learn the basics of RTAB-Map
  • Use the rtabmap_ros package
  • Understand how the loop closure detection works internally
  • Create a 3D Map of an environment
  • Autonomous Navigation using RGB-D SLAM.
