输入一个不完整的点云,会拆解出很多不同的房屋模型,对此建立了点云到mesh的方法:首先把不完整的缺失点云进行补全,之后再通过point到mesh的网络重建三维的房屋模型。Point Cloud Completion可以填充被遮挡的区域,减轻噪声点,降低稀疏度,巩固温和的边缘点。 点到Mesh的重建:三维建筑重建是一个网格变形问题,在输入点云...
This paper presents a new 3D Indoor/Outdoor building dataset (BIO dataset), which is aimed to provide a highly accurate, detailed, and comprehensive dataset to be used for applications related to sematic classification of buildings based on...
constructs a large-scale building dataset in a semi-automated manner and tests it with state-of-the-art deep learning models to analyze their generalization performance. 2.2. Scan-to-BIM Scan-to-BIM refers to the process of creating BIM models from raw point cloud data collected via 3D laser...
The point cloud data was captured in 2012 by a Leica ALS70 instrument and has 7–11 ppm (point per meter) point density. The second dataset is a Dutch national AHN3 point cloud [31] sampling the area of EYE-Amsterdam, the Netherlands. The AHN3 data has a point density of at ...

we hope that our dataset can nurture the development of algorithms that are able to cope with such large-scale geometric data for both vision and graphics tasks e.g., 3D semantic segmentation, part-based generative models, correspondences, texturing, and analysis of point cloud data acquired from...
A key finding is the 7.1% IOU boost in performance achieved when a small real point cloud dataset is augmented by synthetic point clouds for training, as compared to training the classifier on the real data alone. The experimental results confirmed the viability of using synthetic point clouds ...
Therefore, the UAV-SfM point cloud dataset was used to build LoD 2 models. In addition, the comparison between the UAV-SfM and TLS sub-clouds of facades and roofs indicates that the UAV-SfM and TLS point clouds of these objects are highly consistent, therefore, point clouds with a higher...
