【摘要】 结构的低频振动位移监测对于工程领域中的大型旋转机器、大型工程结构有着十分重要的意义。本文采用智能手机,数码相机等常用便携数码拍摄设备代替昂贵的高频CCD拍摄设备,基于KLT算法完成程序设计,为研发低成本的非接触视频位移测量系统建立实验基础。并对比研究了多种常用便携数码拍摄设备应用于非接触视频振动位移测量的优劣。更多还原

【Abstract】 Monitoring low frequency vibration and displacement of structures is of great significance for large rotating machines and large structures in engineering field.This paper uses the intelligent mobile phone,digital camera and other common digital recording equipment instead of the expensive high-frequency CCD photographic equipment to design algorithm routine based on KLT arithmetic,and establishes experimental basis when developing an non-contact video displacement measurement with low cost.Besides,we compare and study the advantages and disadvantages of a variety of common portable digital photographing equipment used in non-contact video vibration displacement measurement with low cost.更多还原
