摘要
采用无人机倾斜摄影测量方法以屋顶平改坡规划设计应用为研究对象,进行屋顶平改坡的三维测图与倾斜三维模型展示任务。首先采用无人机搭载高清相机获取测区的影像数据,然后通过无人机影像数据构建数字正射影像和倾斜实景三维模型,最后基于倾斜实景三维模型进行屋顶二维线划图的绘制,获取屋顶完整信息。应用结果表明,无人机摄影测量方法能够快速获取屋顶的二维和三维模型信息,提高生产效率,有效减少成本,为后续屋顶改造提供数据支持,推进城镇环境综合整治,具有较好的工程应用前景。
The UAV tilt photogrammetry method is adopted to study the planning and design of roof flat slope modification.The 3 D mapping and 3 D model display of roof flat slope modification are carried out.Firstly,the high-definition camera carried by the UAV is used to obtain the image data of the survey area.Then,the digital orthophoto image and the tilted real 3 D model are constructed through the image data of the UAV.Finally,the two-dimensional line drawing of the roof is made based on the tilted real 3 D model to obtain the complete information of the roof.The application results show that the UAV photosurvey method can quickly obtain the two-dimensional and three-dimensional model information of the roof,improve the production efficiency,effectively reduce the cost,provide data support for the subsequent roof reconstruction,promote the comprehensive improvement of urban environment,and has a good engineering application prospect.
