摘要
该文介绍了数码手像机进行工程监测的优点及所需的软件环境。在工程摄影中采用数码像机不仅可以消除像片变形误差、准确提供像机的内方位元素，而且无需冲洗、复制像片，有利于提高效率和像片处理计算机化。这对采用摄影测量进行工程监控提供了有效途径。作者对数码手像机进行大型沉井观测的实例作了简要介绍。
The paper introduces the merit of the digital hand camera to conduct the engineering monitoring and its requirement of software environment .Adopint the digital camera in engineering photography, it can not only eliminate the deformation error of the photograph, accurately present the internal orientation element of the camera, but also endbles the developing, fixing and duplicating of photograph unnecessary, and favorable to cnhance the efficiency and process the photograph computerizing. This the presents an effective way for adopting photogrammetry to conduct the projectmonitoring . A brief introduction of the practical example of proceeding the observation of a large - scale caisson project by a digital hand camera is described.
