Prediction of SLAM ATE Using an Ensemble Learning Regression Model and 1-D Global Pooling of Data Characterization

no code implementations1 Mar 2023 Islam Ali, Bingqing, Wan, Hong Zhang

One of the essential steps to achieve robustness and resilience is the ability of SLAM to have an integrity measure for its localization estimates, and thus, have internal fault tolerance mechanisms to deal with performance degradation.

Sparse Optical Flow-Based Line Feature Tracking

no code implementations7 Apr 2022 Qiang Fu, Hongshan Yu, Islam Ali, Hong Zhang

To achieve this goal, an efficient two endpoint tracking (TET) method is presented: first, describe a given line feature with its two endpoints; next, track the two endpoints based on SOF to obtain two new tracked endpoints by minimizing a pixel-level grayscale residual function; finally, connect the two tracked endpoints to generate a new line feature.

Are We Ready for Robust and Resilient SLAM? A Framework For Quantitative Characterization of SLAM Datasets

no code implementations23 Feb 2022 Islam Ali, Hong Zhang

In order to fill this void, characterization of the operating conditions of SLAM systems is essential in order to provide an environment for quantitative measurement of robustness and resilience.
