摘要
测绘航空摄影近年来发展迅速,采用低空无人飞行器在地勘项目中开展大比例尺地形图测绘已经十分普遍。航空摄影作业数据主要受航线规划、外业飞行、内业处理方面的影响,掌握航空摄影的作业流程和技术要点,对提高地形图的精度和成图效率具有重要意义。本文以甘肃肃北县某地勘项目为例,阐述了无人飞行器开展大比例尺地形图航空摄影的作业流程、方法以及技术要点,以期在实践应用中提供参考。
With the rapid development of Surveying and mapping aerial photography in recent years,it is very common to use low altitude unmanned aerial vehicles to carry out large-scale topographic mapping in geological exploration projects.Aerial photography operation data is mainly affected by route planning,field flight and interior processing.Mastering the operation process and technical points of aerial photography is of great significance to improve the accuracy and efficiency of topographic map.Taking a geological exploration project in Subei County of Gansu Province as an example,this paper expounds the operation process,methods and technical points of large-scale topographic map aerial photography carried out by unmanned aerial vehicle,so as to provide reference in practical application.
