基于倾斜摄影测量技术的明中都城午门遗址三维重建

明中都城为中国都城建筑史的杰作,是南京故宫与北京故宫的蓝本,现为全国重点文物保护单位。午门遗址是目前中都城内遗留相对较为完好的地面建筑。此次针对明中都城午门遗址研究,利用倾斜摄影方法,采集了午门建筑的空间坐标信息与表面纹理信息,通过基于计算机视觉的多图像高精度三维重建技术,获得了基于地理信息的数字化三维模型,达到了对午门遗址残存信息记录、保护与展示利用目的。

The Three Dimensional Reconstruction of Meridian Gate Site in the Middle Capital of the Ming Dynasty Based on Oblique Photogrammetry

The Middle Capital of the Ming Dynasty is a masterpiece of Chinese capital architectural history and the blueprint of Nanjing and Beijing Forbidden City, now it is a national key cultural relics protection units. Meridian Gate site is currently out of the city are left relatively intact. Meridian Gate is the city''s remaining well-preserved ruins of construction on the ground. By the way of oblique photogrammetry, gathering spatial coordinate information and surface texture information of Meridian Gate, and based on multi- precision 3D image reconstruction technique to obtain a digital three-dimensional model based on geographical information, The result shows that it plays a role of recording cultural heritage information, displaying and reusing digital cultural heritage.
