This paper provides an account of the development of the multi‐lens aerial photographic cameras that were constructed in the UK for topographic mapping purposes under the auspices of the Air Survey Committee during the interwar period of the 1920s and 1930s. Three‐, five‐ and seven‐lens cameras were designed and built by the Royal Aircraft Establishment, Farnborough and by Barr & Stroud in Glasgow; these are described in some detail. The results of the mapping tests that were carried out with these cameras are also presented. Comparisons are made with the similar multi‐lens cameras that were constructed in the USA and Europe during the same period. The recent revival of multi‐lens aerial cameras with their oblique pointing lenses is also briefly discussed.

英国在1920年代和1930年代开发用于地形图的多镜头航拍相机

本文介绍了在1920年代和1930年代战争期间由英国航空测量委员会主持在英国制造的用于地形图绘制的多镜头航拍相机的发展情况。三镜，五镜和七镜相机是由范堡罗皇家飞机制造公司和格拉斯哥的Barr＆Stroud设计和制造的。这些将进行详细描述。还介绍了使用这些摄像机进行的映射测试的结果。与同期在美国和欧洲制造的类似多镜头相机进行了比较。还简要讨论了最近使用倾斜指向镜头的多镜头航空摄像机的复兴。
