Learning to Construct 3D Building Wireframes from 3D Line Clouds

1 code implementation25 Aug 2022 Yicheng Luo, Jing Ren, Xuefei Zhe, Di Kang, Yajing Xu, Peter Wonka, Linchao Bao

Line clouds, though under-investigated in the previous work, potentially encode more compact structural information of buildings than point clouds extracted from multi-view images.

Semi-signed neural fitting for surface reconstruction from unoriented point clouds

no code implementations14 Jun 2022 Runsong Zhu, Di Kang, Ka-Hei Hui, Yue Qian, Xuefei Zhe, Zhen Dong, Linchao Bao, Chi-Wing Fu

To reconstruct a better signed distance field, we propose semi-signed neural fitting (SSN-Fitting), which consists of a semi-signed supervision and a loss-based region sampling strategy.
