Performance and current state of conditions of civil infrastructure can be determined using close range photogrammetry (CRP) techniques via high-resolution digital cameras mounted on unmanned airborne vehicles (UAVs). This proposed research describes how appropriate use of unmanned aerial systems (UASs) with their UAVs can be integrated with CRPs to help in infrastructure performance assessment. A UAS covers all of the work that a UAV does and makes that work possible through a ground-based controller, a system of communications connecting the UAVs and the controller, and the personnel and guidelines that keep their use functional and safe. Foundational work first covers selection and acquisition of UAS-CRP technologies as well as development of specific guidelines for operation of UAVs. The acquired UAS-CRP will then be studied in infrastructure investigations related to pavements performance and railway track assessments. All these tasks, if proven effective will increase safety with less boots on the ground, reduce survey costs, increase readiness, and help with ease of use and accuracy for transportation infrastructure condition assessment. The final outcome of the research will present a framework and guidelines on how UAS-CRPs technology can be used to effectively perform pavement and railway track assessments. |
