遺跡の３次元可視化プログラムの開発

Kyushu University is moving to a new campus located in the western part of Fukuoka city. There are many archeological remains such as keyhole shaped mound tombs around the new campus. We have developed an automatic electrical resistivity measuring system named Handy-ARM (Handy Archaeological Resistivity Meter) for archaeological prospections. We carried out electrical resistivity prospecting by Handy-ARM at the keyhole shaped tomb named Shioyoke Kofun in the new campus. After two-dimensional inversion of observed data, we have found that low resistivity anomalies were distributed from 2m to 4m deep of central part of the circular mound and high resistivity anomalies were detected at the slope of the circular mound. We have also developed three-dimensional imaging software using three-dimensional CG (Computer Graphics) to display results of an electrical resistivity survey for an archaeological prospection. It is obviously effective not only for geophysists but also for archaeologists to evaluate survey results by using the three-dimensional imaging program.<br>
