无人机航摄系统在复杂地形应用的关键技术试验

Research on Application of Key Technology in Complex Terrain of UAV Aerial Photography System

随着经济快速发展,我国对于大比例尺地形图的需求越来越高,传统航测技术在生产效率和精度上都无法满足要求。在本次试验中,通过研究GPS实时动态差分技术和数据后处理等关键技术,提高了数据精度。实现了固定翼无人机航摄系统在山区丘陵和城区居民地两种复杂地形的1∶500大比例尺DOM和DEM的制作,通过精度检查表明,其精度完全满足1∶500大比例尺DOM和DEM的要求。同时摆脱了传统航摄影像制作时需要外业像控测量的作业模式,大大提高了生产效率。

With the development of economy, the request of large scale topographic map is more and more high, and the production efficiency and accuracy of the traditional aerial technology can not meet the requirements. In this experiment, through the research of DGPS Real-time Kinematic and data post-processing, the key techniques such as the data precision is improved. Fixed-wing UAV aerial photography system is used in mountainous hilly and urban residents area for two kinds of complex terrain 1 ： 500 large-scale DOM and DEM production. The precision examination showed that its precision completely meets the requirements of 1 ： 500 large-scale DOM and DEM. At the same time the field control is not needed for the traditional aerial image production the production efficiency is greatly improved.
