CE-NPBG: Connectivity Enhanced Neural Point-Based Graphics for Novel View Synthesis in Autonomous Driving Scenes
Mohammad Altillawi, Fengyi Shen, Liudi Yang +2
Current point-based approaches encounter limitations in scalability and rendering quality when using large 3D point cloud maps because using them directly for novel view synthesis…
LiDAR Loop Closure Detection using Semantic Graphs with Graph Attention Networks
Liudi Yang, Ruben Mascaro, Ignacio Alzugaray +4
In this paper, we propose a novel loop closure detection algorithm that uses graph attention neural networks to encode semantic graphs to perform place recognition and then use sem…
Lifelong 3D Mapping Framework for Hand-held & Robot-mounted LiDAR Mapping Systems
Liudi Yang, Sai Manoj Prakhya, Senhua Zhu +1
We propose a lifelong 3D mapping framework that is modular, cloud-native by design and more importantly, works for both hand-held and robot-mounted 3D LiDAR mapping systems. Our pr…
OpenSU3D: Open World 3D Scene Understanding using Foundation Models
Rafay Mohiuddin, Sai Manoj Prakhya, Fiona Collins +2
In this paper, we present a novel, scalable approach for constructing open set, instance-level 3D scene representations, advancing open world understanding of 3D environments. Exis…
