Attention-Enhanced Feature-Based Point Cloud Completion Network for Precision Parts [PDF]

open access: yesSensors
When acquiring point cloud data of precision parts using 3D scanning devices, occlusion or equipment limitations often lead to sparse and incomplete data, resulting in the distortion or loss of key geometric features.

Learning Geometric Transformation for Point Cloud Completion

open access: yesInternational Journal of Computer Vision, 2023
Point cloud completion aims to estimate the missing shape from a partial point cloud. Existing encoder-decoder based generative models usually reconstruct the complete point cloud from the learned distribution of the shape prior, which may lead to ...

Generative adversarial networks for high-fidelity 3D point cloud completion [PDF]

open access: yesScientific Reports
3D point clouds are essential for representing geometric structures in various fields such as autonomous driving and virtual reality. However, real-world data often suffers from incompleteness due to occlusions and noise, and existing completion methods ...

Enhancing the performance of point cloud completion assisted with tactile information

open access: yesEURASIP Journal on Image and Video Processing
Point cloud completion is a crucial task in the field of 3D imaging and is becoming a current research hotspot. However, traditional point cloud completion methods often fail to accurately restore the local details of objects due to the lack of detailed ...

View-Guided Point Cloud Completion [PDF]

open access: yes2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2021
This paper presents a view-guided solution for the task of point cloud completion. Unlike most existing methods directly inferring the missing points using shape priors, we address this task by introducing ViPC (view-guided point cloud completion) that takes the missing crucial global structure information from an extra single-view image. By leveraging

Temporal Point Cloud Completion With Pose Disturbance [PDF]

open access: yesIEEE Robotics and Automation Letters, 2022
Point clouds collected by real-world sensors are always unaligned and sparse, which makes it hard to reconstruct the complete shape of object from a single frame of data. In this work, we manage to provide complete point clouds from sparse input with pose disturbance by limited translation and rotation.

HyperPocket: Generative Point Cloud Completion

open access: yes2022 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2022
Scanning real-life scenes with modern registration devices typically give incomplete point cloud representations, mostly due to the limitations of the scanning process and 3D occlusions. Therefore, completing such partial representations remains a fundamental challenge of many computer vision applications.

Hyperspherical Embedding for Point Cloud Completion

open access: yes2023 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2023
Most real-world 3D measurements from depth sensors are incomplete, and to address this issue the point cloud completion task aims to predict the complete shapes of objects from partial observations. Previous works often adapt an encoder-decoder architecture, where the encoder is trained to extract embeddings that are used as inputs to generate ...
