摘要
无人机以其机动灵活、实时性强、低成本等优势,迅速成为快速获取地理数据的有效平台。以防灾科技学院为例,通过小型多旋翼高精度航测无人机,辅助RTK技术获取高重叠度影像,利用摄影测量软件生成数字正射影像(DOM)和数字表面模型(DSM),基于三维立体测图系统实现地形图要素的提取,结果表明,该技术方案能够满足1:500数字地形图测绘的需要,极大地提高了制图效率。
With its advantages of flexibility,real-time capability and low cost,UAV(Unmanned Aerial Vehicles)has quickly become an effective platform for quickly acquiring geographical data.Disaster prevention institute of science and technology,for example,through a small rotor high-precision aerial drones,auxiliary RTK technology to obtain high degree of overlapping images,using photogrammetry software generated Digital Orthophoto Map(DOM)and Digital Surface Model(DSM),based on three-dimensional topographic map plotting system elements extraction,the results show that the technical solution to meet the needs of 1∶500 digital topographic map surveying and mapping,greatly improved production efficiency.
