摘要：

本文介绍了用日产 Bronika SQ- A1 2 0型非量测相机对东南极拉斯曼丘陵 1 :40 0 0 0摄影比例尺小像幅航片进行加密的情况。通过用武汉测绘科技大学研制的联合平差程序 Wu CAPS软件的带附加参数的光束法区域网平差获得了实地上平面± 2 .82 9m,高程± 4.973 m的加密精度。文中还分析了若干精度问题 ,所得结论对今后的进一步研究将有所裨益

Abstract:

With the development of photogrammetry, photogrammetrists are studying an air photogrammetric method using non metric camera loaded in a light plane. The new method can better serve the photogrammetric purpose, but some disscusions are needed. This paper describes a combined adjustment program system WuCAPS based on 386 personal computer, which developed by Derpartment of Photogrammetry and Remote Sensing at Wuhan Technical University of Surveying and Mapping. Some adjusted results with small format air photographs for Zhongshan station's project on Antarctica are given. These photos are taken with a non metric camera of Bronika SQ A 120 type, made in Japan. The photo scale is 1∶40000. By using the bundle block adjustment with self calibration of WuCAPS, the planimetric accuracy reaches ±2.829m, and the height accuracy reaches ±4.973m in the ground.
