基于直升机平台及非量测数码相机的南极航空摄影测量技术研究

RESEARCH ON NON-METRIC DIGITAL AERIAL PHOTOGRAMMETRY TECHNOLOGY BASED ON HELICOPTER IN ANTARCTICA

使用直升机作为飞行平台并应用哈苏H1D非量测数码相机进行南极中山站和拉斯曼丘陵地区摄影测量。通过对非量测相机标定,获取相机的内方位元素,从而可进行航空摄影测量。两个区域的具体试验表明基于直升机平台和非量测数码相机的航空摄影测量可应用于南极等困难地区的地形图测绘。

This paper introduced the overall flowchart of photogrammetry for Zhongshan Station and Larsemann Hills area in Antarctica using Hasselblad HI D non-metric digital camera by taking helicopter as the platform. Through the calibration of non-metric digital camera, it acquired the interior orientation elements for implementing the aerial photogrammtry. Taking the practical experiments for two areas as example, the results showed that the aerial photogrammetry using non-metric digital camera based on helicopter can be applied for topographic mapping in Antarctica and other remote areas.
