模型机航空近景摄影测量系统的开发和应用

Development and applications of a model airplane-borne photogrammetric system

对于通行困难或作业危险地区的工程,现有大多数位移监测技术耗时耗力,甚至无法实施。卫星遥感、航空摄影测量等技术虽然不受场地条件限制,但测量精度较低,后者还受航空管制等政策的限制。既不受场地条件制约,又有较高精度,且不受航空管制的高效、低成本的位移测量技术具有广泛的应用领域和前景。为此,开发了基于微型模型机的航空近景摄影测量系统。该系统已成功用于阳朔月亮山的低空航拍和大冶铁矿东露天高陡边坡地质调查以及地形测量,取得了良好的效果。

In harsh and/or inaccessible areas,monitoring,measurement and survey using traditional methods are generally time-consuming and laborious,even impossible.Although the techniques of satellite remote sensing and aerial photogrammetry can partially overcome the above restricts,their precisions and resolutions are too low to be used for the purpose of displacement monitoring and geological survey.Moreover,the aerial photogrammetry is subjected to the aviation regulation.It is therefore of great practical intere...
