摘要: 以山西省右玉县杀虎口古长城为例,采用Trimble UX5 HP搭载Sony A7r相机完成数据采集,利用Context Capture软件和PhotoMesh软件进行三维重建,并利用Geomagics软件对三维模型进行精细处理,比较两种软件的空三精度,得出Context Capture软件的空三精度更高。同时利用外业实测检查点对模型进行精度计算,得到Context Capture软件的模型精度,其点位中误差为0.192 m,表明这种方法可以满足实景三维建立模型的要求,为智慧城市的建设提供了强有力的数据保障。

Abstract: Taking the ancient Great Wall of Shahukou in Youyu county, Shanxi province as an example, data acquisition is completed by using Trimble UX5 HP with Sony A7r camera, 3D reconstruction is carried out by using Context Capture software and PhotoMesh software, and 3D model is fine treatment by using Geomagtics software. Comparing the three-dimensional accuracy of the two softwares, the three-dimensional accuracy of Context Capture software is higher. At the same time, the model accuracy of Context Capture software is calculated by using the field survey checkpoints. The mean square error of the points is 0.192 m, which shows that this method can meet the requirements of real 3D model building and provide a strong data guarantee for the construction of smart city.

Key words: unmanned aerial vehicle, oblique photography, 3D modeling, Context Capture, PhotoMesh
