3D Modeling of Bajang Ratu Temple using UAV Photogrammetry with Oblique Images

Abstract

The Bajang Ratu Temple is located in Dukuh Kraton, Temon Village, Trowulan District, Mojokerto Regency, East Java, Indonesia, one of the heritage buildings of the Majapahit Kingdom. 3D modeling is one of the efforts that can be used to carry out reconstruction of the Bajang Ratu Temple. In this study, 3D modeling of Bajang Ratu Temple uses a close-range photogrammetry method with low and high oblique images taken using a non-metric camera on the Unmanned Aerial Vehicle. The results of this study were obtained geometric accuracy, that is RMSEx = 0,043 m, RMSEY = 0,049 m, and RMSEZ = 0,092 m for high oblique images. While, for low oblique images, the geometric accuracy are RMSEx = 0,054 m, RMSEY = 0,062 m, and RMSEZ = 0,120 m. The visual analysis results show that the exterior structure of the 3D model formed has resembled the true Bajang Ratu Temple in reality. Based on the shape’s analysis, the 3D model object has an RMSE value of less than 0.5 m, so that it can appropriate the criteria for Level of Detail of order three that is RMSE < 0.5 m.
