摘要
无人机航空摄影测量技术在国民生产中发挥着越来越大的作用。传统的航空摄影测量都需要一定数量的像控点,对于山地、丘陵和一些复杂的地形,像控点的获取尤为困难,从而大大限制了航空摄影测量的应用。本文以天狼星免像控航测系统为平台,介绍了免像控摄影测量的工作原理和作业流程,运用计算机自动进行内业处理,大大减少了人工干预。通过阐述其在青岛市某区1∶500地形图的应用中进行了精度分析。
Uav aerial photogrammetry technology plays an increasingly important role in national production.The traditional aerial photography measurement needs to be a certain number of locus of control.For mountains,hills and some complicated terrain,it is particularly difficult to obtain the control points,which greatly limits the application of aerial photogrammetry.This paper is based on the system of Sirius-free image control system,introduces the working principle of photogrammetric control photogrammetry and process.The use of computer to automatically carry out the internal processing,greatly reducing the manual intervention.In addition,the precision analysis is carried out in the application of a 1：500 topographic map in an area of Qingdao.
