Debao Huang

I'm a PhD candidate in the Geospatial Data Analytics Group at The Ohio State University.

I started in January 2021, supervised by Prof. Rongjun Qin. My research focuses on large-scale 3D reconstruction (SfM, NeRF, 3DGS, 4DGS) and uncertainty quantification. Additionally, I leverage vision foundation models and multimodal learning to advance large-scale 3D scene understanding. I am working on projects funded by ONR, IARPA, AFRL, and NSF to solve complex 3D geometry problems.

I am currently open to internship and full-time opportunities starting in 2026.

Keywords: Photogrammetry, Computer Vision, Machine Learning, Generative AI, Vision Foundation Models.

Selected Research

Uncertainty
Uncertainty Quantification Framework for Aerial and UAV Photogrammetry through Error Propagation
Debao Huang, Rongjun Qin
arxiv, 2025

This paper presents a novel, self-calibrating method to estimate the uncertainty in the MVS stage, and an uncertainty quantification framework for Aerial and UAV Photogrammetry.

Dynamic Urban Scene Modeling with 3D Gaussian Splatting from UAV Full Motion Videos
Debao Huang, Hanyang Liu, Ningli Xu, Rongjun Qin
ISPRS Archives, 2025

This work presents a method for reconstructing dynamic urban scenes from UAV full-motion videos using 3D Gaussian Splatting, effectively handling moving objects in large-scale environments.

Motion Constraint
Bundle Adjustment with Motion Constraints for Uncalibrated Multi-Camera Systems at the Ground Level
Debao Huang, Rongjun Qin, Mostafa Elhashash
ISPRS Journal of Photogrammetry and Remote Sensing, 2024

This paper derives novel geometric constraints in BA of SfM pipeline that assumes minimal knowns about the uncalibrated multi-camera systems at the ground level. Our proposed constraints are effective in correcting topographical errors (i.e., trajectory drifts) of the reconstruction.

NeRF
Multi-Tiling Neural Radiance Field (NeRF)—Geometric Assessment on Large-Scale Aerial Datasets
Ningli Xu, Rongjun Qin, Debao Huang, Fabio Remondino
The Photogrammetric Record, 2024 (Cover article of 12/2024 issue)

This paper provides multi-camera tiling (MCT) strategy to scale the NeRF on large-scale aerial datasets and a thorough geometry assessment of NeRF.

PlanetScope
An Evaluation of PlanetScope Images for 3D Reconstruction and Change Detection
Debao Huang, Yang Tang, Rongjun Qin
GIScience & Remote Sensing, 2022

Comprehensively evaluates the 3D potential of PlanetScope images by performing accuracy analysis for both 3D reconstruction and change detection.
