无人机倾斜测量在1∶500地形图测量中的应用与分析--基于炎陵县城镇开发边界

Application and Analysis of UAV Tilt Measurement in 1:500 Topographic Map Survey--Based on Town Development Boundary of Yanling County

随着测绘技术装备的日新月异、测绘技术手段的不断提高与创新升级,各种高精尖的数据获取设备、数据处理软件广泛应用于测绘生产,测绘行业的数据获取能力和数据处理能力得到了极大的提高,生产速度有了翻天覆地的变化,无人机倾斜摄影测量技术得到飞速的发展。倾斜摄影测量技术具有运行成本低、工作效率高、作业风险低、分辨率高、灵活性及遥感数据实时性等多种优点。本项目采用无人机倾斜航空摄影(地面分辨率优于1.5cm)、立体测图方式,同时形成实景三维模型、1∶500数字线划图(DLG)、数字高程模型(DEM)、数字正射影像图(DOM)等多种类数据成果。

With the rapid development of surveying and mapping technology and equipment,the continuous improvement and innovation and upgrading of surveying and mapping technology,various sophisticated data acquisition equipment and data processing software are widely used in surveying and mapping production,the data acquisition ability and data processing ability of the surveying and mapping industry have been greatly improved,the production speed has tremendous changes,and the UAV tilt phogrammetry technology has developed rapidly.Tilt photogrammetry technology has many advantages,such as low operation cost,high work efficiency,low operation risk,high resolution,flexibility,and the real-time nature of remote sensing data.This project adopts UAV inclined aerial photography(ground resolution is better than 1.5cm)and stereo mapping method,and forms a real-life 3D model,1∶500 digital line drawing(DLG),digital elevation model(DEM),digital orthophoto image(DOM)and other data results.
