A stereo visual-inertial SLAM approach for indoor mobile robots in unknown environments without occlusions
C Chen, H Zhu, L Wang, Y Liu - IEEE Access, 2019 - ieeexplore.ieee.org
When mobile robots are working in indoor unknown environments, the surrounding scenes
are mainly low texture or repeating texture. This means that image features are easily lost …

Improving structure from motion with reliable resectioning
A common cause of failure in structure-from-motion (SfM) is misregistration of images due to
visual patterns that occur in more than one scene location. Most work to solve this problem …
