摘要
桥梁、隧道、舰船等大型结构变形的全场、高精度、动态测量,是其动态性能实验和质量监测的基本要求。摄像测量具有非接触、高精度、可测点多、实时动态测量等特点,在大型结构的变形监测方面有独特的优势。本文介绍了作者所在科研团队近年来利用摄像测量技术在大型结构变形监测方面的研究新成果和典型应用,包括提出位移传递像机串联网络摄像测量方法与技术,用于自动监测高速铁路、隧道等大型结构的路基沉降;研制天线基座变形摄像测量系统,实时、连续、长时间测量我国远望号测量船的天线基座变形等。
The full scale,high precision and dynamic deformation measurement of large-scale structure,such as bridge,tunnel,ships and so on,is a basic requirement for their dynamic performance experiment and quality monitoring. Compared with other measurement means,videometrics has a lot of advantages in large-scale structure deformation measurement.It can conduct non-contact,real-time dynamic measurement with high precision and multi measuring points.It has unique advantages in deformation monitoring of large-scale structure.In this paper,in large-scale structure deformation monitoring,new achievements and typical applications of videometrics technology obtained by author′s research team in recent years are introduced.It includes the measurement method and technology of displacement transfer and camera series network photography.It can be used to automatically monitor subgrade settlement of high-speed railway,tunnel and other large-scale structures.A camera measuremrnt system was developed.It can real time and continuously measure the deformation of antenna pedestal on observation boat＂Far Sight＂for a long time.
