The c2tam repository contains a ROS stack of a cloud framework for a cooperative visual tracking and mapping. The softwares is tested under ros-fuerte distribution.
This software is based on PTAM "Parallel Tracking and Mapping" (http://www.robots.ox.ac.uk/~gk/PTAM/) library.
Download the stack from the repository:
git clone https://github.com/lriazuelo/c2tam.git
Add the downloaded folder to your
Install any dependencies of the stack
rosdep install c2tam
Install manually the dependencies
sudo apt-get install libsuitesparse-dev libeigen3-dev libxmu-dev libxi-dev
Compile the packages on this order:
rosmake c2tam_msgs rosmake c2tam_srvs rosmake c2tam_tracking rosmake c2tam_mapping rosmake c2tam_visualizer
- Edit camera.cfg file into c2tam_mapping and c2tam_tracking with the calibration of your camera sensor.
- Modify camera_parameters.yaml file into c2tam_tracking/launch folder according with your camera sensor.
Connect your RGB-D camera and launch the http://www.ros.org/wiki/openni_camera Kinect sensor driver
roslaunch openni_camera openni_node.launch
Next, start the C2TAM mapping node
roslaunch c2tam_mapping server.launch
Once the mapping server is running, start the C2TAM tracking node
roslaunch c2tam_tracking client.launch
Finally, launch the C2TAM visualizer node
roslaunch c2tam_visualizer visualizer.launch
When all the nodes are running, we are ready to start the application by calling the service:
rosservice call /c2tam_vslam/start true 0
The visual SLAM starts to build a map from freely hand-held camera image sequence. The c2tam_visualizer node has two displays. On the first one, it can be seen the real image gathered by the camera with the tracked map features backprojected. On the second one, you will see a virtual reconstruction of a 3D world displaying the keyframe locations, and all the 3D map points.
