无人机影像构建文物三维模型研究

3D modeling of the cultural relics with UAV photography

海量点云数据可以很好构建文物的三维建模,常规的建模周期时间长,外业工作量大。利用无人机摄影技术,依据数字摄影测量原理和计算机视觉原理,通过对影像数据进行定向、匹配、空三加密获取点云数据,利用点云数据可以进行三维模型构建,结合实际实验案例进行分析,新方法适合室外文物的三维建模,可达到较好的效果。

The 3D modeling of the cultural relics can be done with the massive data of point cloud. The tradi-tional modeling of cultural relics was longer, and the technical difficulty was greater. With the UAV photography based on the principles of digital photogrammetry and those of computer vision, we obtained point cloud data by directing, matching, empty three encrypting the image data. Then the 3D modeling was constructed with those point cloud data. The experimental results show this method is suitable for the outdoor 3D modeling of cultural relics and can achieve a good effect.
