摘要
论文介绍了利用无人机航测技术对测区倾斜图像构建三维模型的方法,并进行了1∶500大比例尺地形图制作。利用倾斜摄影的三维立体效果,可以快速地获取基本地理信息,通过地物检查点核查,平面精度优于0.1m,高程精度优于0.13m。试验结果证明,这种方法适合于1∶500大比例尺地形图的绘制,特别是对于大规模的地形测量,具有很好的应用前景。
This paper introduces the method of using UAV aerial survey technology to build a 3D model of the tilt image of the survey area,and makes a 1:500 large scale topographic map.Using the 3D effect of oblique photography,basic geographic information can be quickly obtained.The plane accuracy is better than 0.1m,and the elevation accuracy is better than 0.13m through the inspection of ground objects.The experimental results show that this method is suitable for 1:500 large scale topographic map rendering,especially for large-scale topographic survey,and has a good application prospect.
