丝绸之路文物古迹“甘肃锁阳城”三维建模方法研究

Research on 3D Modeling of Suoyangcheng as Cultural Relics of Silk Road

以航空摄影和全野外数字化测量等手段,获取丰富的地形地貌数据,再结合多种GIS数据处理方法获取锁阳城建模数据,通过精细建模和实景贴图技术建立城墙模型,最终在SuperMap平台下建立三维场景。详细介绍了模型数据获取、模型数据处理和建模的具体方法。

This paper got image data by means of aerial photography, and then acquired the terrain data of Suoyangcheng mainly using both the technology of photogrammetry workstation 3D data acquisition and the technology of a full field digital measurement. Combined with a variety of GIS data processing method to acquire the Suoyangcheng modeling data, the paper built walls model through the technology of fine modeling and real mapping, and established 3D scene based on SuperMap. This article discussed the method of modeling data acquisition, data processing and mode building in detail.
