摘要： 针对实际驾驶环境中道路场景及车道线复杂多样的问题,提出一种基于改进Enet网络的车道线检测算法。首先,对Enet网络进行剪枝和卷积优化操作,并利用改进的Enet网络对车道线进行像素级图像语义分割,将车道线从图像中分离出来。然后,采用DBSCAN算法对分割结果进行聚类处理,将相邻车道线区分开来。最后,对车道线聚类结果进行自适应拟合,得到最终的车道线检测结果。该算法在香港中文大学的CULane数据集上进行了训练和测试,结果表明,其标准路面检测准确率达到96.3%,各种路面综合检测准确率为78.9%,图像帧处理速度为71.4fps,能够满足实际驾驶环境中的复杂路况和实时性需求。此外,该算法还在图森未来的TuSimple数据集和实采数据集LD-Data上进行了训练和测试,均取得了实时性的检测结果。
