evaluate_ate_scale

Script to compute the Absolute Trajectory RMSE error for the TUM RGB-D dataset, that automatically aligns the scale of the estimated trajectory with ground-truth. It is useful to evaluate trajectories generated by SLAM or VO algorithms. See the original tool and how to use it here: http://vision.in.tum.de/data/datasets/rgbd-dataset/tools#evaluation

Trajectory and ground-truth are aligned computing a Similarity Transformation (Rotation, Translation and Scale) with the method of Horn: B. K. P.
