Point Cloud GAN

open access: yesCoRR, 2018
Generative Adversarial Networks (GAN) can achieve promising performance on learning complex data distributions on different types of data. In this paper, we first show a straightforward extension of existing GAN algorithm is not applicable to point clouds, because the constraint required for discriminators is undefined for set data.

DPDist: Comparing Point Clouds Using Deep Point Cloud Distance [PDF]

open access: yes, 2020
We introduce a new deep learning method for point cloud comparison. Our approach, named Deep Point Cloud Distance (DPDist), measures the distance between the points in one cloud and the estimated surface from which the other point cloud is sampled. The surface is estimated locally and efficiently using the 3D modified Fisher vector representation.

Predictive point-cloud compression [PDF]

open access: yesACM SIGGRAPH 2005 Sketches on - SIGGRAPH '05, 2005
Point clouds have recently become a popular alternative to polygonal meshes for representing three-dimensional geometric models. 3D photography and scanning systems acquire the geometry and appearance of real-world objects in form of point samples.

3D Point Cloud Recognition Based on a Multi-View Convolutional Neural Network

open access: yesSensors, 2018
The recognition of three-dimensional (3D) lidar (light detection and ranging) point clouds remains a significant issue in point cloud processing. Traditional point cloud recognition employs the 3D point clouds from the whole object.

QUALIFICATION OF POINT CLOUDS MEASURED BY SFM SOFTWARE [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
This paper proposes a qualification method of a point cloud created by SfM (Structure-from-Motion) software. Recently, SfM software is popular for creating point clouds.

Multi-Feature Registration of Point Clouds

open access: yesRemote Sensing, 2017
Light detection and ranging (LiDAR) has become a mainstream technique for rapid acquisition of 3-D geometry. Current LiDAR platforms can be mainly categorized into spaceborne LiDAR system (SLS), airborne LiDAR system (ALS), mobile LiDAR system (MLS), and

An Improved Point Clouds Model for Displacement Assessment of Slope Surface by Combining TLS and UAV Photogrammetry

open access: yesApplied Sciences, 2022
TLS can quickly and accurately capture object surface coordinates. However, TLS point clouds cannot cover the entire surface of the target object, due to block of view and limitation of measurement condition.

A partial overlapping point cloud registration method based on dynamic feature matching

open access: yesDianxin kexue, 2021
The point cloud registration method can effectively complete the registration of point clouds with different overlap rates and various sizes, and ensure the accuracy of the 3D reconstruction model.To address the above issues, a partial overlapping point ...

Ridge-Valley-Guided Sketch-Drawing From Point Clouds

open access: yesIEEE Access, 2018
Sketch-drawing is one of the simplest and most direct means to illustrate 3-D objects. It can not only present geometric features, but also greatly facilitate us to identify and understand the object.
