基于倾斜摄影测量的单体建筑三维建模技术初探

Exploration of 3D Modeling Technology for Individual Buildings Based on Oblique Photogrammetry

为避免传统三维建模中工作量大、生产成本高和模型真实度欠佳的问题,使用消费级无人机进行倾斜摄影测量三维建模。通过对比倾斜摄影测量建模、空地结合三维建模和精细化三维建模3种方法,发现精细化三维建模方法更便捷、模型精细化程度更高。通过实践发现,该方法可用于小范围建筑群建模、非历史建筑类单体建筑建模和简单模型修整,未来可应用于老旧小区改造和小片区城市测绘等项目。

To avoid the problems of heavy workload,high production costs,and poor model credibility in traditional 3D modeling,consumer grade UAV are used for oblique Photogrammetric 3D modeling.By comparing three methods of oblique photogrammetric modeling,3D modeling of air-ground combination,and refined 3D modeling,it was found that the refined 3D modeling method was more convenient and had a higher model precision.Through practice,it has been found that this method can be used for modeling small-scale building clusters,modeling non historical individual buildings,and simple model modification.In the future,it can be applied to projects such as the renovation of old residential areas and urban surveying in small areas.
