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.
