The Development Of A Convenient And Consistent Methodology For Flight Proficiency To Certify Multi-Rotor Uas Pilots For State Departments Of Transportation, Colin Dees
All Dissertations
To fly an unmanned aircraft system (UAS), commonly referred to as a “drone,” the Federal Aviation Administration (FAA) requires pilots to pass a knowledge test. There is no requirement at the state or federal level for drone operators to demonstrate the ability to operate a UAS. The National Institute of Science and Technology (NIST) has created an exam for public and private entities to assess basic UAS flight proficiency. It is the only nationally recognized flight proficiency protocol. NIST does not provide a scoring recommendation and leaves it to the user to determine the minimum criteria to pass. There is …
The Extent Of Drone Education Being Taught In Asc Schools To 4-Year Construction Students, Cheran Teja Dumpati
The Extent Of Drone Education Being Taught In Asc Schools To 4-Year Construction Students, Cheran Teja Dumpati
All Theses
The technology of Unmanned Aircraft Systems (UAS) is growing rapidly in many fields and has become one of the skills in demand in the industry. Universities are one of the primary sources of teaching drone technology with a career-oriented approach. The goal of this study is to investigate the content of the drone curriculum being taught in Associated Schools of Construction (ASC) schools. This includes the topics covered, practical training offered, and the key deliverables taught. This information serves as a foundation for the schools that are looking forward to start drone courses in their department. The research found that …
A Computer Vision-Based Method For Tack Coat Coverage Inspection Using Drone-Collected Images, Aida Da Silva
A Computer Vision-Based Method For Tack Coat Coverage Inspection Using Drone-Collected Images, Aida Da Silva
Graduate Theses, Dissertations, and Problem Reports
Tack coat is a thin asphalt applied between the existing surface and asphalt overlay during road rehabilitation. The uniformity of tack coat coverage plays a vital role in providing adhesive bonding between the two layers in the pavement structures. To ensure tack coat uniformity, the current practice primarily relies on manual inspection during construction by field experts. This process is time-consuming and tedious, and the results can be subjective and error-prone. Drones have emerged as a non-destructive sensing technology in the construction industry for many inspection practices. Unlike other non-destructive inspection technologies, drones offer benefits ranging from accelerating data collection …

Proposal For Purchase Of In-House Drone For Cal Poly’S Construction Management Department, Angel Sanchez
Construction Management
Over the years, the construction industry has been steadily seeing an influx of new technology and innovation that has potential to improve the industry in many ways. One form of technology that has been introduced into the construction industry is Unmanned Aerial Systems (UAS). UAS technology includes drones, photogrammetry capabilities, and the software that links field data to analytic tools. In the past decade, drones in construction have seen a considerable amount of growth and the uses for drones in construction, therefore new job opportunities in construction have been created that require knowledge of UAS technology. As the construction industry …
Diseño De Un Protocolo De Recolección, Procesamiento Y Análisis De Imágenes Vis Y Satelitales Para Aforar Sedimientos En Suspensión Aplicado Al Río Negro, Nicolas Mateo Gomez Benavides, Natalia Vanessa Gil Medina
Diseño De Un Protocolo De Recolección, Procesamiento Y Análisis De Imágenes Vis Y Satelitales Para Aforar Sedimientos En Suspensión Aplicado Al Río Negro, Nicolas Mateo Gomez Benavides, Natalia Vanessa Gil Medina
Ingeniería Civil
Actualmente la cuantificación de sedimentos en suspensión demanda la extracción de muestras en campo y su procesamiento en laboratorio, lo cual implica restricciones logísticas y económicas, que con este trabajo pretendieron ser superadas, utilizando técnicas de visión artificial para determinar la carga de sedimentos a partir de fotografías. El protocolo propuesto para la captura y escalado de imágenes tomadas con drone durante vuelos entre 1 y 150 metros de altura, permite cuantificar su carga sólida y caracterizar morfológicamente el rio. Mediante un modelo potencial que relaciona el área que se captura en la imagen respecto a la altura de vuelo …
Documentation Of Concrete Slabs Prior To Pours, Peter D. Riley
Documentation Of Concrete Slabs Prior To Pours, Peter D. Riley
Construction Management
Concrete slabs in multi-level commercial building projects contain many components that become no longer visible once concrete has been poured. As building designs advance and continue to locate components in concrete, it is important to document what these slabs contain in order to verify accurate craftsmanship and allow for improved future construction workflows and building modernizations. This paper explores current industry needs for proficient documentation as well as practices to achieve this. A case study was conducted, testing four devices that analyzed feasibility factors for realistic implementation by a contractor such as cost, interoperability, and level of skill required for …
Unmanned Aerial And Traversing Vehicle -- A Mobile Platform For Bridge Inspections, Clayton A. Fritsche
Unmanned Aerial And Traversing Vehicle -- A Mobile Platform For Bridge Inspections, Clayton A. Fritsche
Masters Theses
“Unmanned aerial vehicles (UAVs), also known as drones, have been rapidly growing in popularity since their creation. This study aimed to create a robotic platform used to assist in the inspection process of the nation’s aging and deteriorating bridges. To this end, a multimodal inspection robot that utilized both flying and driving technologies, was designed, analyzed, and tested for aerial, traversing, and their transitional operability. The design, herein referred to as the “BridgeBot”, was evaluated both computationally and experimentally. A finite element model of the BridgeBot was established and analyzed under static loading scenarios to help determine stress distributions and …
Use Of Drone Technology On Commercial Construction Projects, Andrew Lin
Use Of Drone Technology On Commercial Construction Projects, Andrew Lin
Construction Management
Every successful construction project is an intricate symphony of project management, jobsite operations, and skilled laborers doing what they do best. While traditional means and methods have proven themselves to be reliable and effective, companies must now look into new and improved approaches to expedite their project delivery and maintain their competitive edge in this booming and demanding market. Furthermore, as expectations for new commercial projects grow, the risks of taking on these projects increase alongside them. Skyscrapers are expected to be taller, buildings more efficient, and company campuses vaster and more state-of-the-art than ever before. With technological innovations such …
Unmanned Aircraft Systems Image Collection And Computer Vision Image Processing For Surveying And Mapping That Meets Professional Needs, James Preston Peterson Ii
Unmanned Aircraft Systems Image Collection And Computer Vision Image Processing For Surveying And Mapping That Meets Professional Needs, James Preston Peterson Ii
Doctoral Dissertations
"Unmanned Aerial Systems (UAS) are rapidly blurring the lines between traditional and close range photogrammetry, and between surveying and photogrammetry. UAS are providing an economic platform for performing aerial surveying on small projects. The focus of this research was to describe traditional photogrammetric imagery and Light Detection and Ranging (LiDAR) geospatial products, describe close range photogrammetry (CRP), introduce UAS and computer vision (CV), and investigate whether industry mapping standards for accuracy can be met using UAS collection and CV processing. A 120-acre site was selected and 97 aerial targets were surveyed for evaluation purposes. Four UAS flights of varying heights …
