本文主要介绍一种用35毫米电影摄影机对空间活动物体瞬间的二维参数进行定量测量的简便方法。文中阐述了测量中的拍摄速度的选择、摄影机与被摄物的布局、参照物的选择及标定、数据处理方法,并通过对直升飞机与某固定目标的交会飞行的实际测量验证了此测试方法的可行性,精度上满足要求。此方法简便易行,费用较小由于不用交流电特别适合野外测量。
This article describes a simple method for quantitatively measuring the two-dimensional parameters of an instantaneous object in space using a 35mm movie camera. This paper expounds the selection of shooting speed, the layout of cameras and objects, the selection and calibration of reference objects, the data processing method in the measurement, and verifies the test by actual measurement of the rendezvous flight between the helicopter and a fixed target The feasibility of the method, the accuracy to meet the requirements. This method is simple and easy to use, less expensive as it is especially suitable for outdoor measurement without AC power.
