GeoOpen3D: Geometry-guided training-free open-vocabulary 3D segmentation via visual foundation models

Shuai Zhang, Zhuoxiao Li, Ou Jing, Tengxi Wang, Zhecheng Shi, Wufan Zhao

Abstract. Open-vocabulary 3D segmentation offers an attractive alternative to closed-set scene parsing, yet directly transferring 2D vision-language models to outdoor point clouds remains difficult because projection disrupts geometric continuity and sparse sampling weakens mask…
