Real-time Localization in Outdoor Environments using Stereo Vision and Inexpensive GPS
2006
18th International Conference on Pattern Recognition (ICPR'06)
Preserved Fulltext
The motion estimation problem is formulated efficiently in the disparity space and results in accurate and robust estimates of the motion even for a small-baseline configuration. ...
Our system relies on stereo vision to robustly estimate frame-to-frame motion in real time (also known as visual odometry). ...
Our goal for this project was to develop an inexpensive localization system using stereo vision and complement it with a low-cost GPS sensor and a suite of inexpensive inertial navigation sensors. ...

Our results show that stereo visual-inertial odometry has a great potential to provide a precise motion estimation because of its complementing sensor modalities and shows superior performance in challenging ...
In this work, we investigate the applicability, challenges and limitations of current visual and visual-inertial motion estimation frameworks for rail applications. ...
Using the IMU as a complementing sensor modality, as in OKVIS, seems to be beneficial in this case. Stereo-SWE still has troubles with feature tracking as in scenario A. ...

In this paper we propose a framework of factorization-based non-rigid shape modeling and tracking in stereo-motion. ...
We construct a measurement matrix with the stereo-motion data captured from a stereo-rig. ...
The notable problem is how to fully utilize the redundant information in the stereo-motion analysis, but practically the more important issue would be how to make the two basic cues complement with each ...

Through the use of the extra information obtained from stereo images, coping with large out-of-plane rotations and translation in depth is now tractable (or at least easier than with a single camera). ...
Generally, 3D head tracking with a single camera is not robust to fast and large outof-plane rotations and translation in depth. ...
Because we assumed Eq. (1) in the beginning, and because Eqs. (6) and (7) are linear with respect to motion parameters α α α and illumination coefficient vectors β β β l and β β β r respectively, we can ...

In our method, compressed 2D video is analyzed by extracting motion vectors. ...
Using the motion vector maps, depth maps are built for each frame and the frames are segmented to provide object-wise depth ordering. ...
This happens when the motion is either too rapid in terms of camera rotation or in the case of camera zoom. Such cases can be detected by analysis of the motion vector maps and dealt with. ...
