摘要
针对传统测量方法无法在短时间内完成大规模测量,以及在阴雨天气中获取的图像质量难以满足需求的问题,本文提出了利用无人机倾斜摄影技术构建城市真实场景三维模型的思路。利用无人机倾斜摄影技术收集甘肃某市约200 km^(2)的图像数据,通过布设少量地面影像控制点,采用航空三角测量建立连接,并对收集的数据进行三维建模。本文实地验证了地面物体的属性信息,利用连续运行参考站系统进行场地坐标采集并验证其精度。结果表明,无人机倾斜摄影模型的地面属性和数学精度符合要求,可以用于真实的三维建模。
In response to the problem that the traditional measurement methods cannot complete large-scale measurement in a short period of time,and the image quality obtained in rainy weather is difficult to meet the requirements,this paper puts forward the idea of using UAV tilt photography technology to build three-dimensional modeling of urban real scene.The UAV tilt photography technology is used to collect approximately 200 km^(2) of image data in a city in Gansu Province,a small number of ground image control points were set up,the aerial triangulation is used to establish the connection.and the three-dimensional modeling of the collected data is carried out.This paper conducts the field verification of the attributen of ground objects,and uses a continuous operation reference station system to collect site coordinates and verify their accuracy.The results show that the ground property and mathematical accuracy of UAV tilt photography model meet the requirements,and can be effectively used in real 3D modeling.
