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。
Full-scale, high-precision and dynamic measurement of large structural deformations such as bridges, tunnels and ships are the basic requirements for dynamic performance tests and quality monitoring. Camera measurement with non-contact, high precision, measurable points, real-time dynamic measurement and other characteristics of deformation monitoring in large structures have unique advantages. This paper introduces the research achievements and typical applications of the author’s research team in the field of large-scale structural deformation monitoring by using the imaging measurement technology in recent years. It includes the methods and techniques of imaging and measuring the serial camera of the displacement transfer camera for automatic monitoring of high-speed railways and tunnels Large-scale structure of subgrade settlement; development of antenna base deformation camera measurement system, real-time, continuous, long time measurement of China’s Yuan Wang antenna measurement of the ship’s base deformation.
