ZAHA
收藏资源简介:
ZAHA是目前最大的用于点云立面语义分割的基准数据集,包含601百万个标注点,引入了立面泛化级别(LoFG),支持对建筑立面的层次理解,涵盖多种建筑风格,并提供本地和全球(即UTM)坐标参考系统。
ZAHA is currently the largest benchmark dataset for point cloud facade semantic segmentation. It contains 601 million annotated points, introduces the Level of Facade Generalization (LoFG), supports hierarchical understanding of building facades, covers diverse architectural styles, and provides both local and global (i.e., UTM) coordinate reference systems.
