| 摘 要： | 三维建模已经广泛应用于文物保护、工程测量、城市服务、应急救灾、林业保护等多个方面。本文结合实际工程经验,对多旋翼无人机近景摄影的古建筑物三维建模进行了研究,提出了一种自主飞行结合手动多高度、多角度拍照的古建筑三维建模方法,并通过多个试验场景,验证了三维模型的精度和质量。同时,引入地面布设的控制点,利用空中三角测量及密集匹配技术,进而获得古建筑上各个特征点的三维坐标,为近景摄影测量在古建筑物变形监测方面的研究提供了新的思路。

| Abstract: | Three-dimensional modeling has been widely used in cultural relics protection, engineering surveys, urban services, emergency disaster relief, forestry protection and other aspects. Based on actual engineering experience, this paper studies the three-dimensional modeling of ancient buildings for close-range photography of multi-rotor drones, and proposes a three-dimensional modeling method for ancient buildings that combines autonomous flight with manual multi-height and multi-angle photography. The experimental scene verifies the accuracy and quality of the 3D model. At the same time, the control points placed on the ground are introduced, aerial triangulation and dense matching technology are used to obtain the three-dimensional coordinates of each feature point on the ancient building, which provides a new idea for the study of close-range photogrammetry in the deformation monitoring of ancient buildings. |
