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.
Keywords: 3D Computer Vision, Photogrammetry, Machine Learning, Generative AI, Vision Foundation Models.

Selected Research
We introduce Olbedo, a large-scale aerial dataset containing 5,664 UAV images for outdoor albedo-shading decomposition in the wild.
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.
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.
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.
This paper provides multi-camera tiling (MCT) strategy to scale the NeRF on large-scale aerial datasets and a thorough geometry assessment of NeRF.
