3D Digital Reconstruction of the Shendao Stone Statues of the Mausoleum of Ming Dynasty Based on Photogrammetry

The Shandao stone statues of the Ming Zu Mausoleum, the head of the three imperial tombs, reflect the highest level of stone carving art in the early Ming Dynasty, which have both historical and artistic value. It is worth studying in depth. After more than 600 years of natural factors such as weathering erosion and man-made destruction during the Cultural Revolution, some stone statues were partially damaged, making it difficult to identify the former style. Based on the analysis, processing, feature extraction and image matching of the digital image of the Shinto stone statue in the Tomb of the Ming Dynasty based on the photogrammetry technology, the paper carries out the spatial geometric positioning, establishes the digital elevation model and obtains the digital orthophoto image. According to the gray level, characteristics and texture, the visual contour map and orthographic image map are studied and formed by statistical classification and computer operation to reproduce the digital image of Shinto lithograph.
