Package Summary

Ros applications for fast visual odometry and mapping from RGB-D data, built on top of the rgbdtools library.

Details

ROS API

rgbd_system.png

The package provides the following ROS nodes/nodelets:

  • rgbd_image_proc: processes raw OpenNI camera data by performing image rescaling, rectification, registration, and depth unwarping. Also see ccny_openni_launch

  • feature_viewer: auxliary node which lets users test out different feature detectors, and visualize feature locations and covariances in rviz

  • visual_odometry: visual odometry based on sparse 3D features.

  • keyframe_mapper: a map server which stores RGBD keyframes, performs (offline) graph-based SLAM, and handles map generation and disk output.

Quick usage

First, launch the device and image processing via ccny_openni_launch.

roslaunch ccny_openni_launch openni.launch publish_cloud:=true

Next, launch visual_odometry.launch for visual odometry, or vo+mapping.launch for visual odometry and mapping interfaces.

roslaunch ccny_rgbd vo+mapping.launch

Launch rviz, and load the vo+mapping.vcg configuration file.

If you are using the mapping interface, you can call the following services to perform graph-based SLAM (offline):

rosservice call /generate_graph 
rosservice call /solve_graph

You can publish the resulting keyframe to rviz:

rosservice call /publish_keyframes  ".*"

Or save the entire map as a pcd:

rosservice call /save_pcd_map /home/your_user_name/my_map.pcd

For more options, consult the individual app pages.
