Fusion of Object Tracking and Dynamic Occupancy Grid Map
This work addresses the challenge of robust environment perception for autonomous driving systems, but it is incremental as it combines existing methods without introducing a fundamentally new paradigm.
The paper tackles the problem of environment modeling in autonomous driving by fusing grid-based and feature-based approaches to leverage their complementary advantages, resulting in a fusion algorithm that generates more realistic hypotheses and enables longer object tracking, as evaluated quantitatively on real sequences in real-time.
Environment modeling in autonomous driving is realized by two fundamental approaches, grid-based and feature-based approach. Both methods interpret the environment differently and show some situation-dependent beneficial realizations. In order to use the advantages of both methods, a combination makes sense. This work presents a fusion, which establishes an association between the representations of environment modeling and then decoupled from this performs a fusion of the information. Thus, there is no need to adapt the environment models. The developed fusion generates new hypotheses, which are closer to reality than a representation alone. This algorithm itself does not use object model assumptions, in effect this fusion can be applied to different object hypotheses. In addition, this combination allows the objects to be tracked over a longer period of time. This is evaluated with a quantitative evaluation on real sequences in real-time.
