基于无人机倾斜摄影的智慧校园三维建模应用研究

随着无人机技术的飞速发展,无人机外业数据采集由传统的垂直方向获取正射影投影图发展到现在的倾斜摄影测量技术,可以实现多角度数据采集,极大提高三维建模的精度和效率。该文对倾斜摄影测量技术及实景三维模型进行研究,并将研究成果应用于智慧校园实景三维建模。通过无人机倾斜摄影技术获取校园遥感影像,选取Context Capture处理遥感影像进行三维建模。并以甘肃建筑职业技术学院为试验区,进行实景三维建模作为验证,取得良好的建模效果。

With the rapid development of UAV technology,the field data acquisition of UAV has developed from the traditional vertical acquisition of orthographic projection to the current oblique photogrammetric technology,which can achieve multi angle needle data acquisition,greatly improving the accuracy and efficiency of 3D modeling.In this paper,the technology of oblique photogrammetry and 3D model of real scene are studied,and the research results are applied to 3D modeling of smart campus.The remote sensing image of the campus is obtained through the tilt photography technology of UAV,and the remote sensing image is processed by Context Capture for 3D modeling.Taking Gansu Vocational and Technical College of Architecture as the experimental area,the real 3D modeling was carried out as a verification,and good modeling results were achieved.
