CeyMo
收藏资源简介:
CeyMo数据集是由斯里兰卡莫拉图瓦大学电子与通信工程系创建,专注于道路标记检测。该数据集包含2887张高分辨率(1920×1080)图像,涵盖4706个道路标记实例,分为11个类别,覆盖多种交通、光照和天气条件。数据集通过手动标注,提供多格式(多边形、边界框和像素级分割掩码)的标注,以支持多样化的道路标记检测算法。CeyMo数据集旨在解决现有公开数据集的局限性,如缺乏挑战性场景、评估脚本缺失等问题,并提供评估指标和脚本,以促进新方法与现有方法的直接比较。该数据集适用于开发先进的驾驶员辅助系统和自动驾驶车辆中的道路标记检测算法。
The CeyMo dataset was developed by the Department of Electronic and Communication Engineering of the University of Moratuwa, Sri Lanka, and focuses on road marking detection. This dataset comprises 2887 high-resolution (1920×1080) images, containing 4706 road marking instances categorized into 11 classes, and covers diverse traffic, lighting, and weather conditions. Annotated manually, the dataset provides annotations in multiple formats including polygons, bounding boxes, and pixel-level segmentation masks, to support a wide range of road marking detection algorithms. This dataset aims to address the limitations of existing public datasets, such as the lack of challenging scenarios and absence of dedicated evaluation scripts. It also provides evaluation metrics and corresponding scripts to enable direct performance comparison between newly proposed methods and state-of-the-art approaches. The CeyMo dataset is applicable for developing road marking detection algorithms for advanced driver-assistance systems (ADAS) and autonomous vehicles.

下载
CeyMo 道路标记数据集的训练集、测试集和样本可以从以下 Google Drive 链接下载:
标注
道路标记标注以三种格式提供:多边形、边界框和像素级分割掩码。多边形标注以 JSON 格式作为基准,边界框标注以 XML 格式和分割掩码以 PNG 格式作为附加标注。每张图像的摄像机和车辆以及测试图像的类别也被标注。
统计
柱状图显示了每个类别的频率,饼图显示了测试集中每个场景的比例。
评估
评估脚本需要安装以下依赖项: bash pip install argparse shapely tabulate
通过运行提供的 Python 脚本可以获得类别、场景和总体结果: bash python eval.py --gt_dir=<gt_dir> --pred_dir=<pred_dir>
