Method Description:
In this work, we firstly utilizing direct visual method with lidar point clouds as input. We utilize the state-of-the-art monocular direct visual odometry DSO as our baseline, and extend it to an odometry handling lidar points cloud. We propose lots of strategy to adapt our approach to a variety of practical scenarios, including lidar points preprocessing, feature extraction.
Parameters:
sliding window size = 5
the number of points per frame = 500

Detailed Results

From all test sequences (sequences 11-21), our benchmark computes translational and rotational errors for all possible subsequences of length (5,10,50,100,150,...,400) meters. Our evaluation ranks methods according to the average of those values, where errors are measured in percent (for translation) and in degrees per meter (for rotation). Details for different trajectory lengths and driving speeds can be found in the plots underneath. Furthermore, the first 5 test trajectories and error plots are shown below.
