Abstract： At present, the lightweight lane line detection network has problems such as poor curve detection effect, insufficient network receptive field and limited real-time performance.Therefore, this paper proposes an improved lightweight lane detection network model. Firstly, to improve the curve detection effect, a direction consistency loss is designed to make the model suitable for the curve scene.Secondly, in order to improve the real-time performance of the network while improving the receptive field, a fusion network of self-attention mechanism and RepVGG is proposed as the backbone network of the model. The total F1-measure of the model tested on the CULane test set reached 70.7%, the accuracy of the test on the Tusimple test set reached 95.92%, and its average inference speed reached 408 FPS. The experimental results show that the model has a certain improvement in performance compared with the current lightweight model, especially the lane line detection effect in the curve scene is significantly improved.
