无人机遥感技术在三维建模中的应用

The application of unmanned aerial vehicle remote sensing technology in 3D modeling

无人机倾斜摄影测量技术已经广泛地应用于测绘领域,以某市作为试验区,完成该试验区三维模型的制作。针对倾斜影像建立的三维模型存在的一些问题,比如悬浮物、建筑物结构变形、纹理缺失等,从而导致所建立的模型存在质量问题,提出了一系列相应的处理技术,并从纹理、位置两方面对模型进行了精度评定,对三维建模的发展具有重要意义。

Drone tilt photogrammetry technology has been widely applied in the field of surveying and mapping,this article takes Xujiaping Town,Lueyang County,Hanzhong City,Shaanxi Province as the experimental area and completes the production of a three-dimensional model of the experimental area.There are some problems with the 3D model established by tilted images,such as suspended solids,structural deformation of buildings,missing textures,etc.which lead to quality issues in the established model,this article proposes a series of corresponding processing techniques and evaluates the accuracy of the model from both texture and position perspectives,which is of great significance for the development of 3D modeling.
