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

R Kataria, J DeGol, D Hoiem - 2020 international conference on …, 2020 - ieeexplore.ieee.org
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 …

H Sarmadi, R Muñoz-Salinas… - IEEE …, 2021 - ieeexplore.ieee.org
Event cameras are a new type of image sensors that output changes in light intensity
(events) instead of absolute intensity values. They have a very high temporal resolution and …

Optimizing fiducial marker placement for improved visual localization

Q Huang, J DeGol, V Fragoso… - IEEE Robotics and …, 2023 - ieeexplore.ieee.org
Adding fiducial markers to a scene is a well-known strategy for making visual localization
algorithms more robust. Traditionally, these marker locations are selected by humans who …
