MD-SLAM: A Multi-Task Deep-Learning-Based Visual SLAM System in Dynamic Environments
Bibliographic record
Abstract
With the development of self-driving vehicles and intelligent robots, visual simultaneous localization and mapping (SLAM) has attracted significant attention. In dynamic environments, non-stationary objects can cause performance degradation of visual SLAM systems. The inaccurate pose and lack of semanticinformation in feature points can lead to incorrect differentiation between static and dynamic points, resulting in a degradation of the visual SLAM system's performance. In this paper, we propose a novel visual SLAM system based on multi-task deep neural networks to address this issue. Specifically, we apply multi-task deep neural networks to extract higher quality and more robust oriented local features and perceive dynamic semantic regions, which are used to better remove dynamic points spatially and potential dynamic points semantically in the SLAM system. We evaluate our method on public datasets, and the results show that our method outperforms existing visual SLAM systems.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
