Lane detection is one of the critical tasks for autonomous driving. Earlier works revolved around semantic segmentation and object detection with a special program for lanes. However, most methods still suffer from unstable post-processing algorithms which leads to a gap between camera input and downstream applications. In this paper, we propose a novel detection presentation form for lanes and design a simple network without any complicated post-process. Specifically, we use sampled gird points to express lane lines and construct a network for the special lane format, which is called SGPLane. Therefore, the network learns a regression branch and a confidence branch to realize end-to-end lane detection by setting the threshold confidence value. Our model is validated on the typical dataset and real-world driving scenes. Experiments on lane detection benchmarks show that our method outperforms previous methods with accuracy score of 96.84% on Tusimple dataset with high FPS and 76.85% on our real-world dataset.
