摘要
近年来,无人机倾斜摄影测量技术取得了突飞猛进的发展,基于无人机倾斜摄影进行大比例尺测图已成为最新的研究热点。本研究深入分析了无人机倾斜摄影大比例尺测图的国内外研究现状以及存在的问题,研究了无人机倾斜摄影测量软硬件系统,制定了无人机倾斜摄影大比例尺测图的总体技术流程,以实际工程为例,采用德国Md4-1000四旋翼无人机搭载双鱼倾斜相机,进行了无人机倾斜摄影,选刺并测量外业控制点,利用Context Capture Center软件生成三维实景模型,并基于倾斜模型采用EPS进行大比例尺测图,生产的数字线划图经检测满足大比例尺地形图的精度要求。
In recent years,drone photographic measurement technology has made rapid progress,and large-scale mapping based on UAV tilt photography has become the latest research hotspot.This paper deeply analyzes the domestic and foreign research status and existing problems of UAV tilt photography large scale mapping,researches the UAV tilt photography measurement software and hardware system,and formulates the overall technical flow of UAV tilt photography large scale mapping.Taking the actual project as an example,the German Md4-1000 quadrotor UAV is equipped with a Pisces tilt camera,which performs the tilt photography of the drone,selects the thorn and measures the field control point,and uses the Context Capture Center software to generate the 3 D real scene model.And based on the tilt model,the EPS is used for large-scale mapping,and the digital line drawing produced by the test is tested to meet the accuracy requirements of the large-scale topographic map.
