BONAI

BONAI包含跨3,300个航空图像的268,958个建筑物实例，每个建筑物以及相应的偏移向量具有完全注释的实例级屋顶和占地面积。与BONAI相比，现有的BFE数据集仅注释建筑足迹。
BONAI的图像取自中国六个代表性城市，即上海，北京，哈尔滨，济南，成都和西安，每个图像集和城市的图像和对象实例的详细数量在下表中报告。

BONAI contains 268,958 building instances across 3,300 aerial images, where each building and its corresponding offset vector are fully annotated with instance-level roofs and footprints. Compared with BONAI, the existing BFE dataset only annotates building footprints. The images of BONAI are collected from six representative cities in China, namely Shanghai, Beijing, Harbin, Jinan, Chengdu and Xi’an. The detailed numbers of images and object instances for each city and its associated image set are reported in the table below.
