Abstract

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
