本文是对各种大型商业航空航天工程部件测量系统进行调查研究的结果。商用飞机制造业的特殊之处在于所涉及部件的规模。精度限制仍然非常接近，尽管尺寸，因此精确的测量方法是必要的，以控制最终产品的质量。介绍了目前测量这类元件的各种方法。这些方法基于三个主要原理：经纬仪、摄影测量和激光技术。每种方法在精度、可重复性、范围和成本等方面各有优缺点。通常还需要考虑每种技术在数据存储和分析方面提供了什么。大多数技术使用基于计算机的系统来存储结果并执行各种计算。这些系统在使用环境方面也有自己的要求。重要的是要考虑一个特定的系统是否可以安装在一个适合测量所需组件的区域，以及确保满足稳定性要求。本文综述了传统光学工具、电子三角测量、电子三边测量、摄影测量、激光跟踪仪和激光扫描仪的原理和特点。
This paper results from research carried out to survey the various large commercial aerospace engineering component measurement systems. The commercial aircraft manufacturing industry is special due to the size of the components involved. Accuracy constraints remain very close, despite the size, and therefore accurate methods of measurement are necessary to control the quality of the final product. A survey of various current methods of measurement for such components is presented. These methods are based around three main principles: theodolites, photogrammetry, and laser technology. Each method has its own advantages and disadvantages in terms of accuracy, repeatability, range and cost. It is also often necessary to consider what each technique provides in terms of data storage and analysis. Most techniques use computer‐based systems to store results and perform various calculations. These systems also have their own requirements in terms of the environment in which they are used. It is important to consider whether a particular system can be installed in an area suitable to measure the required component, as well as ensuring that the stability requirements are met. In this paper the principles and characteristics of conventional optical tooling, electronic triangulation, electronic trilateration, photogrammetry, laser trackers, and laser scanners are reviewed.
