Running time:0.03 s
Environment:5 cores @ 2.5 Ghz (C/C++)

Method Description:
We present a real-time monocular SFM system that
corrects for scale drift using a novel cue
combination framework for ground plane estimation.
Our ground plane estimation uses multiple cues
like sparse features, dense inter-frame stereo. A
data driven mechanism is proposed to learn models
from training data that relate observation
covariances for each cue to error behavior of its
underlying variables. During testing, this allows
per-frame adaptation of observation covariances
based on relative confidences inferred from visual
data.

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.
