Monitoring using Hyperspectral Imaging Analysis of Stone Cultural Heritage in Korea

Abstract eng:
In this study the monitoring on Maaeyeoraesamjonsang (Rock-carved Triad Buddha) at Y onghyeon-ri in Seosan, Korea was conducted taking advantage of hyperspectral image analysis. As a result of analysis, the damage rates at the time of dismantlement of protective facilities and for five years having elapsed after the conservative treatment were calculated to have brown discoloration 36.6%, white discoloration 3.3%, and biological damage 15.6%. The biodeterioration is a new damage type having not been identified at the time of conservation inside the protective facilities. The NDVI of creatures inhabiting on the surface of Rock-carved Triad Buddha is -0.19, which was analyzed to be lower than the vegetation inhabiting on the surrounding rocks, if it continues to be managed under a current environment the damage by creatures is judged to increase.
