Facade parsing is a vital technology for applications such as urban modeling, urban planning, and digital twin city construction. High-resolution facade images are particularly important for achieving fine-grained building reconstruction. However, existing facade datasets rarely contain images with resolutions exceeding 2K × 2K. In this paper, we introduce a new dataset featuring much higher-resolution images captured from various angles and with denser window distributions. We also propose a novel method to automatically compute the perspective transformation matrix for generating corrected facade images, which is used to create a twin version of the dataset after perspective correction. Furthermore, we introduce a new network GLNet, designed to achieve superior facade parsing results using high-resolution images as input. Experimental results on three public datasets (CMP, CFP, and ETRIMS) as well as our own dataset demonstrate that GLNet outperform existing methods in facade segmentation.
