SDLane: Efficient Lane Detection via Sparse Anchors and Dynamic Fusion
The researchers developed SDLane, a lane detection model that reduces the required number of line anchors to a count matching the actual lane instances. Tested on four datasets, including a newly created heavy rain dataset named RainyLane, the model achieves an F1-score of 79.76% at a processing speed of 486 frames per second on the CULane test set using only five anchors.
Why it matters — It eliminates the need for computationally heavy feature extraction and fusion components like Feature Pyramid Networks or attention mechanisms, enabling high-speed, accurate lane detection on resource-constrained hardware during extreme weather and night conditions.
