内容記述 | The Wareishi Rock Cliff Sculpture, carved in A.D. 1300 on a core stone of granite, designated as an important cultural property of the Hiroshima Prefecture, is located near a shoreline of the Sagi Island, Mihara City, Japan. It is pointed out by the local people that the sculpture seems to have recently been suffering from rapid degradation more and more due to the direct influence of tidal ebb and flow. The present three-dimensional shape of this sculpture was investigated through multi-view stereo technique in order to estimate the present degradation state exactly. On the other hand, the same technique was also applied on a replica of the sculpture made in 1986 using a mold and exhibited in the Hiroshima Prefectural History Museum. The difference revealed by the measurement between the present shapes of the sculpture and the replica can be basically regarded as the degradation of the sculpture during these 30 years. As a result, the difference between the shapes of the sculpture and the replica was detected mainly on the middle part of the core stone constituting a horizontal belt of ca. 20 cm parallel to the sea level, and the total area of the places where more than 3 mm displacement was detected constitutes ca. 0.56% of the whole measured area. Accordingly, the degradation of the Wareishi Rock Cliff Sculpture does not seem to be recently accelerated so much but to be progressing at not so different pace as the history of the sculpture, especially following the sea level rise. If the degradation extends up to the face of the sculpture in the future, some countermeasure may be required. | |||||
