摘要
由于传统的测绘方法依靠人工实地测量,目前,成图效率和成图质量不能满足工程的需要。本文应用无人机倾斜摄影测量技术代替传统人工测量对1∶500地形图进行快速制作。通过成果的精度分析表明,倾斜摄影测图方法可以满足1∶500地图的精度要求。
As the traditional surveying and mapping methods of 1∶500 scale topographic map still relies on manual field measurement,the efficiency and quality of mapping cannot meet the needs of current engineering.In this paper,the UAV tilt photogrammetry technology is used to replace the traditional manual measurement in the rapid production of 1∶500 scale topographic map.Through the accuracy analysis of the results,the tilt photogrammetric mapping can meet the accuracy requirement of 1∶500 scale topographic map.
