Applications of vision-based systems for bridge deformation measurement

摘要：

　　Vision-based systems offer a promising way for displacement measurement and receive increased attention in civil structural monitoring.This study investigates the potential of consumer-grade cameras for bridge deformation monitoring.The system is firstly validated in laboratory conditions to study the sensing accuracy of three representative tracking methods.Then a field monitoring test is performed on a short-span railway bridge using the same camera system.Analysis results indicate that the system based on a consumer-grade camera could provide accurate deformation data in field testing.
