摘要
随着测绘测量技术的不断发展,采用无人机通过倾斜摄影的方式获取被摄物体空间信息、表面纹理信息的测绘手段,被广泛的应用在大面积地形、地物测量领域。在小面积城市改造项目中,三维实景模型的精度问题始终是困扰测绘作业人员的一大难题,文中通过航摄方案的制定、飞行参数的设计、模型处理的流程与三维实景模型精度验证方法等方面对无人机倾斜摄影测量技术的应用进行总结,以期对类似项目工程提供新的解决方案。
With the continuous development of surveying and mapping technology,unmanned aerial vehicle(UAV)is widely used in the field of surveying large areas of terrain and ground objects to obtain spatial information and surface texture information of photographed objects by means of oblique photography.In a small area of city reconstruction project,the precision of 3D model of real problem is always a difficulty of the work of surveying and mapping personnel.By the aerial plan formulation,the design of the flight parameters,model processing process and 3D imaging model accuracy testing method of unmanned aerial vehicle(UAV)tilt photogrammetry technology is summarized.Finally,the results may provide new solutions for similar engineering projects.
