Cracks and Potholes in Road Images

This database contains images of defects in paved roads in Brazil. The database was developed using images provided by DNIT (National Department of Transport Infrastructure), through the Access to Information Law - Protocol 50650.003556 / 2017-28. The database contains: * 2235 images from highways in the states of Espirito Santo, Rio Grande do Sul and the Federal District, caught between 2014 and 2017; and * Each image has 3 masks - binary images in png format - separated for each type of annotation: road, crack and pothole. The annotation of the road consisted of demarcating the total region corresponding to the vehicle's road. The annotation of cracks and potholes consisted of the selection of the defect as a whole, maintaining its shape as much as possible.

本数据库收录巴西铺装道路的路面缺陷图像。本数据库依托巴西国家交通基础设施局（DNIT，National Department of Transport Infrastructure）依照《信息获取法》提供的图像构建，相关协议编号为50650.003556/2017-28。
本数据库包含以下内容：
- 2014年至2017年间采集的2235张公路图像，拍摄区域覆盖圣埃斯皮里图州、南里奥格兰德州与巴西联邦特区；
- 每张图像均配有3张PNG格式的二值掩码（mask）图像，分别对应道路、裂缝与坑洼三类标注。
道路标注需划定车辆通行路面的完整区域；裂缝与坑洼的标注则需完整框选缺陷整体，尽可能保留其原始形态。
