摘　　要：针对传统大比例尺测图外业工作量大、人工成本高、效率低等问题,文章提出了利用无人机影像裸眼三维模型绘制地形图的方法。首先运用无人机技术获取目标区域的影像数据,然后利用Pix4Dmapper软件对影像数据进行处理并建立目标区域的三维模型,最后将三维模型导入EPS三维测图系统中完成地形图的绘制。通过与三维激光扫描技术生成点云模型并构建的地形图进行对比分析,结果表明,无人机影像裸眼三维模型产生的中误差较小,能够应用于大比例尺地形图的高精度测绘任务。Aiming at the traditional large-scale mapping field workload,high labor cost,low efficiency,and other problems.This paper proposes a method of drawing topographic maps using naked-cye 3D models of UAV images.Firstly,we use UAV tchnology to obtain the image data of the target area,then we use Pix4Dmapper software to proccss the image data and establish the 3D model of the target area,and finally,we import the 3D model into the EPS 3D mapping system to complete the drawing of topographic maps.By comparing with the method of generating a point cloud model and constructing a topographic map by 3D laser scanning technology,the results show that the naked-eye 3D model of a UAV image produces a less neutral error,which can be applied to the high-prccision surveying and mapping task of the largc-scale topographic map.
