Hznu Facade Dataset

We used the Canon M50 Mark II camera, along with the DJI Mavic Air and DJI Mavic 3 drones, to capture high-resolution facade images across various urban regions of Hangzhou, China. The dataset contains a total of 624 high-resolution facade images. The average resolution of all images is 4056 × 3856. The "original" folder contains the original dataset, which includes facade images, annotated JSON files, and the homography matrices obtained through the perspective correction algorithm. The "perspective correction" folder contains the dataset after perspective correction, including the corrected facade images and the corresponding annotated JSON files, which represent sematic segmentation.Facade images are named in increasing order, with those starting with "c" representing camera-captured facade images, and those starting with "d" representing drone-captured facade images.我们使用佳能（Canon）M50 Mark II相机，以及大疆（DJI）Mavic Air和大疆（DJI）Mavic 3无人机，在中国杭州市的多个城区采集了高分辨率建筑立面图像。本数据集总计包含624张高分辨率立面图像，所有图像的平均分辨率为4056 × 3856。 "original"（原始）文件夹存储原始数据集，其中包含立面图像、带标注的JSON文件，以及通过透视校正算法得到的单应性矩阵（homography matrices）。"perspective correction"（透视校正）文件夹存储经过透视校正后的数据集，包含校正后的立面图像与对应的带标注JSON文件，这些文件用于语义分割（semantic segmentation）。立面图像以递增序号命名，其中以"c"开头的文件为相机拍摄的立面图像，以"d"开头的文件为无人机拍摄的立面图像。
