arXiv — cs.CV•Thursday, November 13, 2025 at 5:00:00 AM
PositiveArtificial Intelligence
The introduction of TopoStreamer marks a significant advancement in the field of autonomous driving, specifically in lane segment topology reasoning. By addressing the limitations of existing methods, TopoStreamer enhances the accuracy of road network reconstruction, which is vital for safe and efficient autonomous maneuvers such as turning and lane changing. The model incorporates innovative features like streaming attribute constraints to maintain temporal consistency, dynamic lane boundary positional encoding for real-time updates, and lane segment denoising to better capture lane patterns. These improvements were assessed using the OpenLane-V2 dataset, demonstrating TopoStreamer's superior performance compared to state-of-the-art methods. This development not only contributes to the ongoing evolution of autonomous driving technology but also underscores the importance of precise lane segment understanding in ensuring the safety and effectiveness of self-driving vehicles.
