摘要: 进入21世纪以来,在生态文明建设背景下,中国的土地整治项目迅速发展。同时,随着近几年无人机的高速发展,倾斜摄影测量技术逐渐走进人们视野,并被广泛应用在土地整治项目中。基于多源数据融合的方法,利用无人机搭载多镜头相机,从各个角度拍摄建筑物,能快速高效地还原出建筑物顶部以及立面形态,模型效果更为精细,可为土地整治工程提供基础地理数据,并应用在土地整治项目的规划、设计、施工等全过程。本文将多源数据融合的实景三维建模技术引入土地整治中,提出了相关解决方案和技术流程,并对实景三维模型在土地整治方面的应用做了介绍。

Abstract: Since the beginning of 21st century, land consolidation projects have rapidly developed under the background of ecological civilization construction in China. With the rapid development of unmanned aerial vehicle (UAV), the technology of the oblique photography measurement comes into the public’s vision and has been widely used in the land consolidation projects. Based on the method of multisource data fusion, using multi-len cameras, UAV takes pictures for the buildings from different angles and regain the forms of the tops and sides of the buildings efficiently. More accurate details of models can be achieved. This technology can provide basic geographic data for land consolidation projects. Such data can be applied to many areas, such as planning, design and construction of land consolidation projects. Here, we introduce the use of actual 3D model technology from multi-source data fusion into land consolidation projects, and propose related solutions and technical processes.
