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.
