\b RGBD-SLAM Implements a SLAM-Frontend based on structure from
motion using visual features to identify keypoints in the RGBD
image of a kinect. It makes use of the g2o SLAM backend to
compute a globally consistent trajectory from the individual
transformations provided by the frontend.

\section codeapi Code API
The main classes are the following:
<ul>
<li>Node - Holds the data for a graph node, e.g., the extracted features and their position in the image plane and the local 3D coordinate systems.
It provides functionality to find the transformation to another node and for publishing the associated pointcloud.</li>
<li>GraphManager - Decides for each Node, which edges are included in the graph. Stores all Nodes with valid edges and optimizes the camera pose graph globally (or locally) with g2o as SLAM backend.
Provides functionality to send (ROS-Msgs) or save (to PCD File) the globally consistent whole model.</li>
</ul>
The following classes are mainly for communication with ROS and the user:
<ul>
<li>OpenNIListener - Subscribes to the openni topics, constructs a node for each image-pointcloud pair and hands it to the graph manager. Online visualization results are sent out.</li>
<li>Graphical_UI - Constructs a QT GUI for easy control of the program</li>
<li>RosUi - a UI for controlling the program via ROS service calls</li>
<li>QtROS - Sets up a thread for ROS event processing, to seperate SLAM-computations from the GUI</li>
<li>GLViewer - OpenGL based display of the 3d model</li>
</ul>
<!--
Provide links to specific auto-generated API documentation within your
package that is of particular interest to a reader. Doxygen will
document pretty much every part of your code, so do your best here to
point the reader to the actual API.
If your codebase is fairly large or has different sets of APIs, you
should use the doxygen 'group' tag to keep these APIs together. For
example, the roscpp documentation has 'libros' group.
