Dense Visual Odometry and SLAM (dvo_slam)

NOTE: this is an alpha release APIs and parameters are going to change in near future. No support is provided at this point.

These packages provide an implementation of the rigid body motion estimation of an RGB-D camera from consecutive images.

• dvo_core

  Core implementation of the motion estimation algorithm.

• dvo_ros

  Integration of dvo_core with ROS.

• dvo_slam

  Pose graph SLAM system based on dvo_core and integration with ROS.

• dvo_benchmark

  Integration of dvo_slam with TUM RGB-D benchmark, see http://vision.in.tum.de/data/datasets/rgbd-dataset.

• sophus

  ROS package wrapper for Hauke Strasdat's Sophus library, see https://github.com/strasdat/Sophus.

Installation

Checkout the branch for your ROS version into a folder in your ROS_PACKAGE_PATH and build the packages with rosmake.

• ROS Fuerte:

  git clone -b fuerte git://github.com/tum-vision/dvo_slam.git
  rosmake dvo_core dvo_ros dvo_slam dvo_benchmark
  

Usage

Estimating the camera trajectory from an RGB-D image stream:

TODO

For visualization:

• Start RVIZ
• Set the Target Frame to /world
• Add an Interactive Marker display and set its Update Topic to /dvo_vis/update
• Add a PointCloud2 display and set its Topic to /dvo_vis/cloud

The red camera shows the current camera position. The blue camera displays the initial camera position.
