3d Scene Reconstruction With Micro-Aerial Vehicles And Mobile Devices, Ivan Dryanovski

Dissertations, Theses, and Capstone Projects

Scene reconstruction is the process of building an accurate geometric model of one's environment from sensor data. We explore the problem of real-time, large-scale 3D scene reconstruction in indoor environments using small laser range-finders and low-cost RGB-D (color plus depth) cameras. We focus on computationally-constrained platforms such as micro-aerial vehicles (MAVs) and mobile devices. These platforms present a set of fundamental challenges - estimating the state and trajectory of the device as it moves within its environment and utilizing lightweight, dynamic data structures to hold the representation of the reconstructed scene. The system needs to be computationally and memory-efficient, so …
