摘要
当前,无人机作为一种快速、有效的影像获取手段,不仅弥补了卫星遥感技术获取数据的不足,还能利用多角度、大范围获取地面纹理信息,为城市三维建模提供重要的技术支持。本文对基于低空无人机影像的城市三维模型构建展开了介绍,分析低空无人机影像城市三维建模的精度评估,并通过研究区域的三维模型、成图结果的精度进行了分析,实验表明:利用低空无人机摄像控制点布设,可达到三维模型精度要求,旨在为有关需要提供帮助。
At present,as a fast and effective image acquisition method,drones not only make up for the lack of satellite remote sensing technology to obtain data,but also can use multiple angles and wide range to obtain ground texture information,which provides important technical support for urban three-dimensional modeling.This paper introduces the construction of urban 3D model based on low-altitude UAV image,analyzes the accuracy of urban 3D model of low-altitude UAV image,and analyzes the accuracy of regional 3D model and graphic results.The experiment shows that the precision requirement of 3D model can be achieved by using low-altitude UAV camera control points to provide assistance for the relevant needs.
