摘要
以倾斜摄影测量技术获得的多方位航拍影像数据资料为基础,结合Smart3D Capture软件平台自动制作测绘区域实景三维模型,为指挥救援、设置安置点和评估地质灾害风险等提供了基础,为估算受灾面积等提供了直接数据信息。通过实践表明,无人机倾斜摄影测量技术与实景三维模型技术相结合,在地质灾害应急测绘中取得了良好的应用效果,具有成图快、精度高的优势,因此应加强该技术的推广使用。
Based on multi-directional aerial photography data obtained by tilt photogrammetry technology,combined with Smart3D Capture software platform automatically produces a real-life 3D model of mapping area,it provides the basis for commanding rescue,setting up settlements and evaluating geological hazard risk,and provides direct data information for estimating the disaster area.Through practice,it is shown that the combination of the drone tilt photogrammetry technology and the real 3D model technology has achieved good application effect in the emergency mapping of geological disasters,and has the advantage of fast graph and high precision,so the promotion and use of this technology should be strengthened.
