CAD Model-Based 3D Scene Reconstruction
Accurate scene reconstruction from an image or a video is essential for various applications in robotics and augmented reality. One common method involves retrieving the best-matching CAD model for each observed object from a database and aligning it with the corresponding input. This technique …

Underwater Refractive Camera Calibration and 3D Scene Reconstruction
… focuses on refractive camera calibration and 3D reconstruction. It starts with investigating geometric models and calibration methods for dome-port camera systems, then introduces an open-source refractive Structure-from-Motion (SfM) solution that integrates refraction throughout the …

LARGE-SCALE NEURAL 3D SCENE RECONSTRUCTION, RENDERING, AND BEYOND
This thesis advances neural 3D reconstruction into a scalable and robust process for real-world applications. While techniques like NeRF and 3D Gaussian Splatting (3DGS) show promise, they face challenges in scalability, robustness to imperfect camera poses, and consistency across distributed …

"""Travelling Without Moving"": A Study on the Reconstruction, Compression, and Rendering of Three-Dimensional Environments for Telepresence"
… we study issues related to free-view 3D-video, and in particular issues of 3D scene reconstruction, compression, and rendering. We present four main contributions. First, we present a novel algorithm which performs surface reconstruction from planar arrays of cameras and generates …

Robust Video Object Tracking via Camera Self-calibration
In this dissertation, a framework for 3D scene reconstruction based on robust video object tracking assisted by camera self-calibration is proposed, which includes several algorithmic components. (1) An algorithm for joint camera self-calibration and automatic radial distortion correction based on …

Dynamic Scene Editing via Semantically Trained 3D Guassians
Image-based 3D scene reconstruction continues to be a challenge as it involves solving both the sufficient 3D representation problem and the 3D reconstruction itself. One approach to tackle the rendering problem is 3D Gaussian Splatting because of its potential to produce fast and realistic renders …

Stereo Matching Based on Edge-Aware T-MST
… an important role in many applications such as 3D scene reconstruction. In this thesis, a novel dense stereo matching method is proposed based on edge-aware truncated minimum spanning tree (T-MST). Instead of employing non-local cost aggregation on traditional MST which is only generated from …

Large-scale probabilistic aerial reconstruction
… much emphasis has been placed on large-scale 3D scene reconstruction from a single data source such as images or distance sensors, models that jointly utilize multiple data types remain largely unexplored. In this work, we will present a Bayesian formulation of scene reconstruction from …

Alive Scene: Participatory Multimodal AI Framework for Collective Narratives in Dynamic 3D Scene
This thesis introduces "Alive Scene," an online participatory platform for recording dynamic 3D environments and building collective interpretations of objects, events, and atmospheres within them. For instance, a user can browse a recording of a room and describe objects or events to locate them; …

Broadband World Modeling and Scene Reconstruction
… perception algorithms, this thesis explores scene reconstruction and world modeling. The process involves two main steps. The first is stereo correspondence using block matching algorithms with filtering to improve the quality of this matching process. The disparity maps are then transformed …

Sensor Fused Scene Reconstruction and Surface Inspection
Optical three dimensional (3D) mapping routines are used in inspection robots to detect faults by creating 3D reconstructions of environments. To detect surface faults, sub millimeter depth resolution is required to determine minute differences caused by coating loss and pitting. Sensors that can …
