传统的摄像测量技术用于测量物体三维位姿及其变形时,通常只能应用于可通视的物体之间或处于同一个视场的物体之间。多摄像机接力传递位姿测量通过接力传递的方式,可以实现对大型结构体中不通视物体之间或大视场范围内物体之间的位姿及其变形进行测量。本文首先对多摄像机接力传递位姿测量方法的基本原理进行了阐述;然后,通过对其硬件结构特点进行分析,提出了相应的软件功能模块与程序控制流程;最后,按照经典的"客户机-服务器"模式分别开发设计了分机软件和主机软件,并用VisualC++语言予以实现。经过大量室内、室外及海上实船实验证明,该软件系统操作简单,使用方便,运行稳定可靠,可扩展性较强。
Traditional videometric approach could not be used to measure the pose deformation of objects in a large viewing field or between intervisible objects in the large structures.Pose Relay Measurement System Using Multi-cameras(PRMSUMC) could be used to overcome the difficulties encountered in applying traditional videometric to deformation measurement between non-intervisible objects.First,basic principle of PRMSUMC was discussed.Then,functional module as well as flow chart of the software design was proposed based on the structure of the system' hardware.Finally,Client software and host software were designed and developed according to the classic Client/Server architecture in Visual C++ platform.A large number of experiments conducted both outdoors and indoors and real ship measurements show that the software system is designed stably and reliably,and it is convenient to use as well as good extendibility.
