SeedFormer: Patch Seeds based Point Cloud Completion with Upsample Transformer [PDF]

open access: yesEuropean Conference on Computer Vision, 2022
Point cloud completion has become increasingly popular among generation tasks of 3D point clouds, as it is a challenging yet indispensable problem to recover the complete shape of a 3D object from its partial observation.

Fused Projection-Based Point Cloud Segmentation

open access: yesSensors, 2022
Semantic segmentation is used to enable a computer to understand its surrounding environment. In image processing, images are partitioned into segments for this purpose.

Repairing triangle meshes built from scanned point cloud [PDF]

open access: yes, 2007
The Reverse Engineering process consists of a succession of operations that aim at creating a digital representation of a physical model. The reconstructed geometric model is often a triangle mesh built from a point cloud acquired with a scanner ...

Point clouds in BIM [PDF]

open access: yesIOP Conference Series: Earth and Environmental Science, 2016
The representation of physical buildings in Building Information Models (BIM) has been a subject of research since four decades in the fields of Construction Informatics and GeoInformatics. The early digital representations of buildings mainly appeared as 3D drawings constructed by CAD software, and the 3D representation of the buildings was only ...

Self-Ordering Point Clouds

open access: yes2023 IEEE/CVF International Conference on Computer Vision (ICCV), 2023
In this paper we address the task of finding representative subsets of points in a 3D point cloud by means of a point-wise ordering. Only a few works have tried to address this challenging vision problem, all with the help of hard to obtain point and cloud labels.

Orienting point clouds with dipole propagation [PDF]

open access: yesACM Transactions on Graphics, 2021
Establishing a consistent normal orientation for point clouds is a notoriously difficult problem in geometry processing, requiring attention to both local and global shape characteristics. The normal direction of a point is a function of the local surface neighborhood;

Restoration of Individual Tree Missing Point Cloud Based on Local Features of Point Cloud

open access: yesRemote Sensing, 2022
LiDAR (Light Detection And Ranging) technology is an important means to obtain three-dimensional information of trees and vegetation. However, due to the influence of scanning mode, environmental occlusion and mutual occlusion between tree canopies and ...

Two-point correlation properties of stochastic "cloud processes'' [PDF]

open access: yes, 2007
We study how the two-point density correlation properties of a point particle distribution are modified when each particle is divided, by a stochastic process, into an equal number of identical "daughter" particles. We consider generically that there may

VIPDA: A Visually Driven Point Cloud Denoising Algorithm Based on Anisotropic Point Cloud Filtering

open access: yesFrontiers in Signal Processing, 2022
Point clouds (PCs) provide fundamental tools for digital representation of 3D surfaces, which have a growing interest in recent applications, such as e-health or autonomous means of transport.

New instruments and technologies for Cultural Heritage survey: full integration between point clouds and digital photogrammetry [PDF]

open access: yes, 2010
In the last years the Geomatic Research Group of the Politecnico di Torino faced some new research topics about new instruments for point cloud generation (e.g. Time of Flight cameras) and strong integration between multi-image matching techniques and 3D
