Meixiang Quan, Songhao Piao, Minglang Tan, Shi-Sheng Huang
2018 arXiv   pre-print
In this paper, we present a novel tightly-coupled probabilistic monocular visual-odometric Simultaneous Localization and Mapping algorithm using wheels and a MEMS gyroscope, which can provide accurate,  ...  Then the novel odometer error term is formulated using the odometer preintegration model and it is tightly integrated into the visual optimization framework.  ...  ACKNOWLEDGMENT This paper is supported by National Science Foundation of China[grant number 61375081]; a special fund project of Harbin science and technology innovation talents research [grant number  ...

2017 2017 IEEE International Conference on Robotics and Automation (ICRA)  
In this paper, we present a vision-aided inertial navigation system (VINS) for localizing wheeled robots.  ...  To address this limitation, we extend VINS to incorporate low-frequency wheel-encoder data, and show that the scale becomes observable.  ...  be combined in a tightly-coupled manner into standard VINS estimators.  ...
