Abstract

Candi Singasari merupakan salah satu situs warisan dunia dimana upaya untuk konservasi, inventarisasi, dan dokumentasi cagar budaya tersebut diperlukan. Sebagai langkah awal yang dapat dilakukan dalam upaya dokumentasi cagar budaya adalah membentuk model rekosntruksi 3D Candi Singasari. Adapun teknologi yang ditawarkan dalam pemodelan rekonstruksi 3D bangunan begitu bervariasi dengan kelebihan dan kelemahan masing-masing seperti teknologi LiDAR, laser scanner, dan fotogrametri jarak dekat. Dewasa ini, perkembangan dalam dunia fotogrametri untuk kegiatan pemodelan 3D begitu pesat hingga adanya metode yang berkembang saat ini yaitu metode videogrametri. Penelitian ini menggunakan teknologi videogramteri dan metode SfM untuk membentuk rekonstruksi 3D Candi Singasari. Teknologi videogrametri memiliki kelebihan seperti akuisisi data yang sederhana, harga ekonomis, minim perubahan fotometrik dalam gambar, dan daya overlap tinggi dari data yang dihasilkan. Kriteria yang digunakan dalam rekonstruksi 3D Candi Singasari menggunakan klasifikasi Level of Detail (LoD). Pada penelitian ini difokuskan pada dua aspek yaitu aspek evaluasi visual rekonstruksi 3D dan perhitungan nilai ketelitian geometrik struktur Candi Singasari. Hasil evaluasi visual rekonstruksi 3D diperoleh bentuk point cloud sejumlah 308.248 titik, dense cloud sejumlah 1.126.457 titik, dan textured yang meliputi 225.291 titik (permukaan/face) dan 113.595 vertex dari 161 frame video dengan rata-rata deteksi fitur tiap frame video sejumlah 2.242 titik yang diolah menggunakan metode structure from motion (SfM). Sedangkan evaluasi untuk validasi nilai geometrik struktur Candi Singasari diperoleh dari hasil korelasi dan uji standar kesalahan. Hasil korelasi antara variabel ICP ukuran model rekonstruksi 3D terhadap ukuran di lapangan menunjukkan nilai kolerasi untuk koordinat easting sebesar 0.998, koordinat northing sebesar 0.997, dan koordinat Z 0.998. Adapun untuk nilai uji standar kesalahan untuk koordinat easting diterima sebesar 83%, koordinat northing diterima sebesar 91.7%, dan koordinat Z diterima sebesar 91.7% juga nilai RMSE koordinat easting sebesar 0.177 meter, northing sebesar 0.194 meter, dan Z sebesar 0.168 meter. ======================================================================================================================== Singasari Temple is one of the world heritage site where efforts for conservation, inventory, and documentation of cultural heritage needed. As a first step to do is to form a 3D model of reconstruction for the Singasari Temple. The technology offered in the modelling of a 3D building reconstruction is so varied with the advantage and disadvantage of each technology such as LiDAR, Laser Scanner, and close range photogrammetry. Now, photogrammetry technique developments for 3D modelling activity so fast in the world that their methods were developed at this time such a videogrammetry method. This studyresearch uses videogrammetry method and SfM (Structure from Motion) for 3D building reconstruction of the Singasari Temple. Videogrammetry method has advantages such as simply of data acquisition, economical price, minimum photometric change in the image, and the generated power of high overlap data. Criteria used for Singasari 3D reconstruction use level of detail (LOD) classification. In this study focused on two aspects, visual evaluation of 3D reconstruction and value calculation of the geometric accuracy of Singasari Temple structure. The result of visual evaluation of 3D reconstruction is obtained the point cloud a number of 308,248 points, dense point cloud number 1,126,457 points, and the textured cover 225,291 points (surface), and 113,595,161 vertex of video frames with the average detection feature each video frame number 2,242 points whichs is processed using method of structure from motion (SfM). While the evaluation for validation of the geometric value structure of Singasari Temple is obtained from the correlation between two variables and standard test error. The correlation between the variable ICP 3D reconstruction model size to the size of the field shows the correlation value for 0.998 amounted to easting coordinate, northing coordinate of 0.997, and Z coordinate of 0.998. as for the value of standard test for easting coordinate error accepted by 83%, northing coordinate 91.7%, and Z coordinates 91.7% and RMSE value for easting coordinate 0.177 meters, northing coordinate 0.194 meter, and Z coordinate 0.168 meters.
