摘要
随着无人机技术的高速发展,无人机航测已成为生产大比例尺地形图的主要手段。立体像对采集方式一直是传统航测与无人机航测主要采用生产地形图的方式,随着倾斜摄影的迅猛发展,利用实景三维模型生产地形图也逐渐被接受,两种生产方式各有优缺点,两者结合能提升生产效率和成图精度。主要介绍南宁市勘察测绘地理信息院利用倾斜摄影实景三维和竖直摄影立体像对相结合生产大比例尺地形图的流程、项目生产中出现的问题和注意事项、该方法的优缺点及工作建议。
The rapid development of unmanned aerial vehicle( uav) technology makes the uva aerial photogrammetry a major means of production of topographic map. And the Stereopair acquisition has always been the main method used in traditional and uva aerial photogrammetry. with the high-speed development of oblique photography,Realistic 3 D Mapping is gradually adopted in the topographic map production. In view of the advantages and disadvantages of two methods,the combination will improve precision and efficiency of production and mapping. Based on the which this paper mainly introduces the procedure,problems,precautions,advantages and disadvantages,and suggestions in the production of large scale topographic map.
