    • 摘要: 由于车道线的多样性以及交通场景的复杂性等问题,车道线检测是一项具有挑战性的任务。其主要表现在当车辆行驶在拥堵、夜晚、弯道等车道线不清晰或被遮挡的道路上时,现有检测方法的检测结果并不理想。本文基于检测方法的框架提出了一种轴注意力引导的锚点分类车道线检测方法来解决两个问题。首先是车道线不清晰或缺失时存在的视觉线索缺失问题。其次是锚点分类时用混合锚点上的稀疏坐标表示车道线带来的特征信息缺失问题,从而导致检测精度下降,所以通过在骨干网络中添加轴注意力层来聚焦行向和列向的显著特征来提高精度。在TuSimple和CULane两个数据集上进行了大量实验。实验结果表明,本文方法在各种条件下都具有鲁棒性,同时与现有的先进方法相比,在检测精度和速度方面都表现出综合优势。

       

      Abstract: Lane detection is a challenging task due to the diversity of lane lines and the complexity of traffic scenes. The detection results of the existing detection methods are not ideal when the vehicle is driving in congestion, at night, and the lane lines are not clear or blocked on the road such as curves. Based on the framework of detection methods, a method that axial attention-guided anchor classification lane detection is proposed to solve two problems. The first is the problem of missing visual cues when lane lines are unclear or missing. The second problem is the lack of feature information caused by using sparse coordinates on mixed anchors, which leads to a decline of detection accuracy. Therefore, an axial attention layer is added to the backbone network to focus on prominent features of the row and column directions to improve the accuracy. Extensive experiments are conducted on the TuSimple and CULane datasets. Experimental results show that the proposed method is robust under various conditions while showing comprehensive advantages in terms of detection accuracy and speed compared with existing advanced methods.
