照相测量技术在飞机大部件检测中的研究与应用

摘要

数字化测量技术是自动化、智能化装配装备发展的技术基础和关键,测量系统直接为设备提供位置信息,可有效避免设备定位误差对系统定位精度的影响.现代飞机制造领域常见的数字化测量技术与系统主要包括激光跟踪仪、电子经纬仪、电子全站仪、室内GPS(iGPS)、自动制孔系统中的孔位找正与法向找正、工业近景摄影测量和激光雷达等.以中航工业陕飞在某型机首次采取的工业近景摄影测量技术(照相测量技术)为例,对照相测量技术开展的研究与应用工作进行了系统的介绍.%The digital measurement technology is the technology foundation and key of automation,intelligentized equip-ment development.The measurement system is directly for the equipment to provide location information,and can effective-ly avoid the effect of the positioning errors on the positioning precision of the system equipment.The modern aircraft manu-facturing field of common digital measurement technology and system mainly includes a laser tracker,electronic theodolite, electronic theodolite indoor GPS (iGPS),automatic system holes in the hole position,industrial close range photogramme-try,laser radar and so on.The AVIC Shaanxi aircraft in a certain type of aircraft takes industrial close range photogramme-try technology (photogrammetry)as an example for the first time,the detailed photographic measurement technology to carry out research and application system is introduced.
