本文提出了动态摄影测量的概念。时间测量是动态摄影测量中的重要内容。文章分析讨论了间歇式和棱镜补偿摄影中几种时间测量的方法,认为通常胶片上记录的时标只能计算摄影频率。时间测量精度与摄影时间分辨率、象点位置、计算方法和计时方式有关。在动态测量分析中时间误差应给予足够重视。 This paper presents the concept of dynamic photogrammetry. Time measurement is an important part of dynamic photogrammetry. The paper discusses several methods for measuring time in intermittent and prism-compensated photography. It is generally assumed that only the photographic frequency can be calculated for the time scale recorded on the film. Time measurement accuracy and photography time resolution, pixel location, calculation methods and timing methods. In the dynamic measurement of time error should be given enough attention.
