GMC: Grid Based Motion Clustering in Dynamic Environment
This addresses the limitation of conventional SLAM algorithms that assume static scenes, enabling applications in real-world dynamic environments.
The paper tackles the problem of visual SLAM in dynamic environments by proposing GMC, a lightweight grid-based motion clustering approach for filtering dynamic objects, achieving more accurate results than state-of-the-art methods on the TUM dataset.
Conventional SLAM algorithms takes a strong assumption of scene motionlessness, which limits the application in real environments. This paper tries to tackle the challenging visual SLAM issue of moving objects in dynamic environments. We present GMC, grid-based motion clustering approach, a lightweight dynamic object filtering method that is free from high-power and expensive processors. GMC encapsulates motion consistency as the statistical likelihood of detected key points within a certain region. Using this method can we provide real-time and robust correspondence algorithm that can differentiate dynamic objects with static backgrounds. We evaluate our system in public TUM dataset. To compare with the state-of-the-art methods, our system can provide more accurate results by detecting dynamic objects.
