Transverse bridge displacement measurement using a laser carried by unmanned aerial system

摘要：

　　This research aims to develop a technology for reference-free transverse bridge displacement measurements using Laser Doppler Vibrometer(LDV)sensors mounted to unmanned aerial vehicles(UAV).Initial testing focused on characterizing the constituent components of the system: the behavior of the copter UAV,the data from the LDV,and the expected data from current measurements of this kind using conventional methods.The data of the LDV sensor was compared to a common tool for linear displacement,the linear variable differential transformer(LDVT),for an analysis of the relative data outputs; first with both sensors stationary on the ground,and second with the LDV fixed to the UAV.The data collected from the first configuration was used as a reference to determine the effects of UAV mounting on the data output of the LDV.These data were collected outdoors,measuring movements of a rigid body simulating the vibrations of a train crossing.
