浅谈三维地形建模系统及无人机在单体建筑建模中的应用

Application of 3D Terrain Modeling System and UAV in Single Building Modeling

由于传统的二维地形建模所反映的地理信息已经远远不能满足现代经济社会发展的需求,并且严重制约着地理信息系统技术的快速发展。在科技日新月异的今天,三维地形建模系统技术应运而生。这种精确描绘并表达现实世界的技术,为人们提供了一个直观逼真的虚拟环境,应用于生活的领域也越来越广泛,成为了世界各国研究的热点。无人机遥感在三维建模中的应用也越来越广泛,并以其成本较低、精度较高和建立的三维模型清晰逼真等优势在未来三维建模过程中具有非常大的潜力。

The geographical information provided by the traditional 2D terrain modeling is far from meeting the needs of modern economic and social development,and it severely restricts the rapid development of GIS technology.Thanks to the appearance of 3D terrain modeling system technology,an intuitive and vivid virtual world is accurately depicted.It is also used in other fields of our life and has become a research hot spot.In 3D modeling UAV is more and more widely applied,which provides accurate and reliable remote sensing image data,and has great potentials in the future 3D modeling process due to its low cost,high precision and clear images.
