BirdNeRF: Fast Neural Reconstruction of Large-Scale Scenes From Aerial Imagery

no code implementations7 Feb 2024 Huiqing Zhang, Yifei Xue, Ming Liao, Yizhen Lao

In this study, we introduce BirdNeRF, an adaptation of Neural Radiance Fields (NeRF) designed specifically for reconstructing large-scale scenes using aerial imagery.

DFR: Depth from Rotation by Uncalibrated Image Rectification with Latitudinal Motion Assumption

1 code implementation11 Jul 2023 Yongcong Zhang, Yifei Xue, Ming Liao, Huiqing Zhang, Yizhen Lao

Despite the increasing prevalence of rotating-style capture (e. g., surveillance cameras), conventional stereo rectification techniques frequently fail due to the rotation-dominant motion and small baseline between views.

Towards Nonlinear-Motion-Aware and Occlusion-Robust Rolling Shutter Correction

1 code implementation ICCV 2023 Delin Qu, Yizhen Lao, Zhigang Wang, Dong Wang, Bin Zhao, Xuelong Li

This paper addresses the problem of rolling shutter correction in complex nonlinear and dynamic scenes with extreme occlusion.

Revisiting Rolling Shutter Bundle Adjustment: Toward Accurate and Fast Solution

no code implementations CVPR 2023 Bangyan Liao, Delin Qu, Yifei Xue, Huiqing Zhang, Yizhen Lao

We propose a robust and fast bundle adjustment solution that estimates the 6-DoF pose of the camera and the geometry of the environment based on measurements from a rolling shutter (RS) camera.

FEC: Fast Euclidean Clustering for Point Cloud Segmentation

1 code implementation16 Aug 2022 Yu Cao, Yancheng Wang, Yifei Xue, Huiqing Zhang, Yizhen Lao

Segmentation from point cloud data is essential in many applications such as remote sensing, mobile robots, or autonomous cars.

Rolling Shutter Pose and Ego-motion Estimation using Shape-from-Template

no code implementations ECCV 2018 Yizhen Lao, Omar Ait-Aider, Adrien Bartoli

Once the virtual deformations have been recovered using SfT, the camera pose and ego-motion are computed by registering the deformed scene on the original template.

A Robust Method for Strong Rolling Shutter Effects Correction Using Lines With Automatic Feature Selection

no code implementations CVPR 2018 Yizhen Lao, Omar Ait-Aider

We present a robust method which compensates RS distortions in a single image using a set of image curves, basing on the knowledge that they correspond to 3D straight lines.
