Abstract  

Using three-dimensional landscape modeling to do traditional village digitization has the advantages of high efficiency and reduction degree. By launching the reconstruction of 13 villages in southern Anhui, with multi-rotor aircraft which carries five cameras to complete the villages’ image data acquisition and preprocessing and, in combination with ContextCapture software to complete aerial triangulation and reconstruction, the model of village model is finally acquired and the model window is transferred and used in the website of the digital museum of the traditional village of China. The results show that this method can be applied to village of model building, and automatically produce dioramas with high resolution, good topological relations and rich details, thus playing an important role in the construction of digital museum of Chinese traditional village. Through the analysis of the data processing time of multiple villages, the authors have obtained the intrinsic relationship between aerial triangulation calculating time and data acquisition time, and give some suggestions on the implementation of the aerial task under the context of traditional villages.
