https://www.youtube.com/watch?v=fqWdSfN9FiA 100 fps & Very Low Drift Visual Odometry - New College Data Set (source code available) http://lelaps.de/projects.html The video shows the results of estimating visual odometry and independent motion on the New College data set (http://www.robots.ox.ac.uk/NewCollegeData/). Visual odometry is obtained by the algorithm of Badino and Kanade [1] that minimizes the reprojection error of tracked features. Features are tracked by the KLT algorithm. Independent motion is obtained by tracking feature position and velocity over time by means of a Kalman filter.

Main window: the arrows show the prediction of position of the tracked features in 2 seconds. Color encodes the 3D Euclidean speed from green to red. Top-right: optical flow vectors of the tracked features. The color encodes the length of the optical flow vector. Middle-right: color encoded stereo disparities from green to red. Bottom-right: estimated traveled path by dead-reckoning (no loop closure) The source code is available on SourceForge.net: http://sourceforge.net/projects/qcv/
