摘要
无人机测绘中的地理信息定位技术是近年来航空遥感技术的主要发展方向,传统的测绘方法一般是针对地理信息特点进行分析,在地理信息定位方面存在一定不足,因此给予无人机测绘的地理信息定位技术也应运而生。通过无人机测绘所收集的信息进行拼接、矫正、处理,从而构建一个地理信息定位,同时运用误差方程来明确定位的控制点,再将控制点的向量坐标作为带权虚拟观测值,按照控制点的不同进行划分,选择无人机测绘获取较为清晰的坐标与图像,最终测算出地理信息定位的均值和均方差,实现精确性的信息定位。主要针对无人机摄影测绘的优势进行分析,并提出了基于无人机测绘的地理信息定位技术。
The geographic information positioning technology in UAV surveying and mapping is the main development direction of aerial remote sensing technology in recent years.The traditional surveying and mapping methods are generally based on the characteristics of geographic information,and there are some deficiencies in geographic information positioning.Therefore,the geographic information positioning technology for UAV surveying and mapping has emerged as the times require.The information collected by UAV surveying and mapping is spliced,corrected and processed to construct a geographic information positioning.At the same time,the error equation is used to define the positioning control points.Then the vector coordinates of the control points are taken as the weighted virtual observation values.According to the different control points,the more clear coordinates and images obtained by UAV surveying and mapping are selected,and finally the geographic information is calculated.The mean and mean square deviation of information location are used to realize accurate information location.This paper mainly analyzes the advantages of UAV photogrammetry,and puts forward the geographic information positioning technology based on UAV mapping.
