Improvement of robustness of the Dual Floor Image Tracking odometry measurement

Dual Floor Image Tracking (DFIT) is a dead reckoning component, which acquires optical flows of ground images from two cameras. The robot that is equipped with the DFIT can measure its position and rotation without being affected by slip or drift. Noncontact feature of the DFIT enables to add-on robots with an arbitrary driving mechanism. This paper presents the design principle of the DFIT and the features of RT component with experimental evaluation.
