Large Scale and Complex Structure Grotto Digitalization Using Photogrammetric Method: A Case Study of Cave No. 13 in Yungang Grottoes

A breakthrough in high-precision digitalization of large-volume cultural heritage assets has been achieved using photogrammetry and laser scanning, addressing the challenge of millimeter-level accuracy for complex structures. The study demonstrates a method that ensures geometric consistency across entire sites while capturing intricate local details, exemplified by the 3D reconstruction of Cave No. 13 in Yungang Grottoesusing over 280,000 images. This approach resolves issues of large-scale aerial triangulation and maintains color fidelity, setting a new standard for digital preservation of immovable heritage.
