摘要
随着无人机倾斜摄影技术的快速发展,无人机倾斜摄影测量的快速建模已成为测绘领域的一项高新技术。基于无人机倾斜摄影测量建模技术,采用Smart3D专业软件,经过影像处理、联合区域网平差、多视影像密集匹配及纹理映射等关键技术,结合蚌埠市滨湖新区城市三维建模的实验,快速实现该区域实景三维模型的构建。通过对城市三维建模工作流程和建模精度进行探讨,实践证明,该方法完全可以满足项目的要求。
With the rapid development of UAV tilt photography,the rapid modeling of UAV tilt photography has become a new and high technology in surveying and mapping.Based on UAV tilt photogrammetry modeling technology,using Smart 3D professional software,through image processing,joint area network adjustment,multi-vision image intensive matching and texture mapping and other key technologies,combined with urban three-dimensional modeling experiments in Binhu New Area.The construction of 3D model of real scene in this area is realized quickly.Through discussing the urban 3D modeling workflow and modeling precision,it is proved that this method can meet the requirements of the project.
