摘要
传统的全站仪、RTK地形图测绘方法精度高,但由于野外地形复杂,因此内外业工作量大.而基于无人机倾斜摄影测量技术进行地形图测绘能减少外业工作量,但存在近地地物三维模型分辨率和精度低、纹理映射不足等方面的局限性.本文提出一种无人机影像融合近地影像的空地一体三维建模技术,经验证,该技术为地形图测绘提供了更多侧面纹理信息和地物细节,提高了倾斜摄影三维模型的整体精度,可以满足 1∶500 地图的绘制要求.
Abstract
The traditional total station and RTK topographic map mapping methods have high precision,but due to the complex field terrain,so the workload is large.However,the topographic mapping based on uav tilt photogrammetry technology can reduce the work-load of field work,but it has some limitations such as low resolution and precision of 3d model of near-ground objects and insufficient texture mapping.In this paper,an air-ground integrated 3D modeling technology of uav image fusion with near-earth image is pro-posed.It has been proved that this technology provides more side texture information and ground object details for topographic map mapping,improves the overall accuracy of 3d model of tilt photography,and can meet the requirements of 1∶500 map drawing.
