【摘要】：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。
[Abstract]:With the rapid development of economy, the demand for large scale topographic maps in China is getting higher and higher, and the traditional aerial survey technology can not meet the requirements in terms of production efficiency and accuracy. In this experiment, the data accuracy is improved by studying the key technologies such as GPS real-time dynamic difference technology and data post-processing. The fabrication of fixed-wing UAV aerial photography system in 1 渭 500 large scale DOM and DEM in mountainous, hilly and urban residential areas is realized. the accuracy check shows that the accuracy fully meets the requirements of 1 脳 500 large scale DOM and DEM. At the same time, it gets rid of the operation mode which needs the field image control measurement in the traditional aerial photography production, and greatly improves the production efficiency.
