Usage Of Drone For Building Facade Inspection, Sahara Adhikari
Usage Of Drone For Building Facade Inspection, Sahara Adhikari
Master's Theses (2009 -)
The taller the building the higher the risk caused by pieces breaking off from the building façade. 13 major cities in the USA have regulations that mandate building façade inspected by a certified professional as per regulations imposed by local authority. Conventional ways of inspecting build facades are manual contact methods where a certified professional inspects the building façade with the help of scaffolding, mobile cranes, or monorails. Visual inspections with contact methods face several challenges, including poor safety, productivity, and reliability. The results of visual inspection can be reliable when dealing with small structures with easily visible parts, but …

Detecting Invasive Insects Using Uncewed Aerial Vehicles And Variational Autoencoders, Scott Daniel Stewart
Master's Theses (2009 -)
In this thesis, we use machine learning techniques to address limitations in our ability to monitor pest insect migrations. Invasive insect populations, such as the brown marmorated stink bug (BMSB), cause significant economic and environmental damages. In order to mitigate these damages, tracking BMSB migration is vital, but it also poses a challenge. The current state-of-the-art solution to track insect migrations is called mark-release-recapture. In mark-release-recapture, a researcher marks insects with a fluorescent powder, releases them back into the wild, and searches for the insects using ultra-violet flashlights at suspected migration destination locations. However, this involves a significant amount of …

Detecting Invasive Insects Using Unmanned Aerial Vehicles, Brian Stumph
Master's Theses (2009 -)
A key aspect to controlling and reducing the effects invasive insect species have on agriculture is to obtain knowledge about the migration patterns of these species. Current state-of-the-art methods of studying these migration patterns involve a mark-release-recapture technique, in which insects are released after being marked and researchers attempt to recapture them later. However, this approach involves a human researcher manually searching for these insects in large fields and results in very low recapture rates. This thesis proposes an automated system for detecting released insects using an unmanned aerial vehicle. Our system utilizes ultraviolet lighting technology, digital cameras, and lightweight …
Data Fusion For Vision-Based Robotic Platform Navigation, Andrés F. Echeverri
Data Fusion For Vision-Based Robotic Platform Navigation, Andrés F. Echeverri
Master's Theses (2009 -)
Data fusion has become an active research topic in recent years. Growing computational performance has allowed the use of redundant sensors to measure a single phenomenon. While Bayesian fusion approaches are common in general applications, the computer vision community has largely relegated this approach. Most object following algorithms have gone towards pure machine learning fusion techniques that tend to lack flexibility. Consequently, a more general data fusion scheme is needed. The motivation for this work is to propose methods that allow for the development of simple and cost effective, yet robust visual following robots capable of tracking a general object …

Real Time Control Framework Using Android, Aaron Pittenger
Master's Theses (2009 -)
One potential application for a smartphone-type device is a flight management and control computer for an unmanned aerial vehicle (UAV). The hardware employed in most smartphones and tablets has the capabilities necessary to fly an air vehicle without user interaction. The user can pre-program in a flight plan and the smartphone will do the rest. In the past, this real time control application has been done using many separate sensor packages and processors, but never on a single, stand-alone device. Also, capabilities such as the high definition camera present on most smartphones can take photographs and store them on the …
