RA-NeRF: Robust Neural Radiance Field Reconstruction with Accurate Camera Pose Estimation under Complex Trajectories
Qingsong Yan, Qiang Wang, Kaiyong Zhao +4
Neural Radiance Fields (NeRF) and 3D Gaussian Splatting (3DGS) have emerged as powerful tools for 3D reconstruction and SLAM tasks. However, their performance depends heavily on ac…
3D Gaussian Splatting for Fine-Detailed Surface Reconstruction in Large-Scale Scene
Shihan Chen, Zhaojin Li, Zeyu Chen +3
Recent developments in 3D Gaussian Splatting have made significant advances in surface reconstruction. However, scaling these methods to large-scale scenes remains challenging due…
A Deep Single Image Rectification Approach for Pan-Tilt-Zoom Cameras
Teng Xiao, Qi Hu, Qingsong Yan +3
Pan-Tilt-Zoom (PTZ) cameras with wide-angle lenses are widely used in surveillance but often require image rectification due to their inherent nonlinear distortions. Current deep l…
SphereDepth: Panorama Depth Estimation from Spherical Domain
Qingsong Yan, Qiang Wang, Kaiyong Zhao +3
The panorama image can simultaneously demonstrate complete information of the surrounding environment and has many advantages in virtual tourism, games, robotics, etc. However, the…
