Abstract

Structure from Motion merupakan teknik permodelan tiga dimensi menggunakan sekumpulan gambar dengan tingkat overlap tinggi dalam menangkap struktur tiga dimensi secara keseluruhan dari lokasi yang dilihat dari berbagai macam posisi. Model tiga dimensi diperoleh dengan menggunakan perangkat lunak seperti Agisoft Metashape dan MicMac GUI. Studi kasus penelitian ini ialah Gedung Teknik Geofisika dan Monumen PWK-ITS. Penggunaan MicMac GUI dikarenakan bersifat opensource serta masih sedikitnya jurnal yang membahas terkait perangkat lunak ini. Didapatkan hasil RMSE pada model tiga dimensi yang diolah menggunakan Agisoft Metashape pada nilai x sebesar 0,025 m; nilai y sebesar 0,037 m; nilai z sebesar 0,021 m dan pada model tiga dimensi Monumen PWK didapatkan RMSE sebesar 0,020 m. MicMac GUI memiliki RMSE nilai x sebesar 0,066 m; nilai y sebesar 0,129 m; nilai z sebesar 0,118 m dan pada Monumen PWK didapatkan RMSE sebesar 0,011 meter. Secara visual, model tiga dimensi yang dihasilkan oleh Agisoft Metashape mampu memberikan hasil visual yang lebih baik pada tiap sisi gedung maupun pada objek monumen daripada model tiga dimensi yang dihasilkan oleh MicMac GUI. Jumlah tie points pada Agisoft Metashape sebanyak 81.222 tie points sedangkan pada MicMac GUI didapatkan 2.476.115 tie points. Hasil dari Agisoft Metashape tercapai hingga LOD 3, pada hasil MicMac GUI belum mampu hingga LOD 3. Hasil C2CD pada model tiga dimensi gedung yang diolah menggunakan Agisoft Metashape mayoritas point cloud menunjukkan jarak antar point cloud sebesar 0 meter terhadap point cloud referensi. Sedangkan MicMac GUI pada sisi depan, kiri, dan kanan gedung menunjukkan jarak antar point cloud sebesar 0 meter terhadap point cloud referensi, kecuali pada bagian belakang terdapat jarak antar point cloud sekitar 0.210 meter hingga 0.630 meter terhadap point cloud referensi. Surface density model tiga dimensi gedung yang diolah menggunakan Agisoft Metashape memiliki 1.310.161 points cloud dan hasil MicMac memiliki 1.600.529 points cloud. Pengolahan pada Agisoft Metashape lama pemrosesan diselesaikan dalam waktu 16 menit 24 detik dan pada MicMac GUI lama pemrosesan diselesaikan dalam waktu 1 jam 16 menit 26 detik.

Structure from Motion is a three-dimensional modeling technique that uses a set of images with a high level of overlap to capture the overall three-dimensional structure of the location seen from a variety of positions. Three-dimensional models were obtained using software such as Agisoft Metashape and MicMac GUI. The case study of this research is the Geophysical Engineering Building and the PWK-ITS Monument. The use of MicMac GUI is due to at least one journal that discusses related software, especially in its research aspects. RMSE results were obtained on a three-dimensional model processed using Agisoft Metashape at a value of x of 0.025 m, y of 0.037 m, and z of 0.021 m, and on the three-dimensional model Monumen PWK RMSE of 0.020 m. The MicMac GUI has an RMSE value of x of 0.066 m, a y value of 0.129 m, a z value of 0.118 m, and on the PWK Monument, an RMSE value of 0.011 meters. Visually, the three-dimensional model produced by Agisoft Metashape is able to provide better visual results on each side of the building as well as on monumental objects than the three-dimensional model generated by the MicMac GUI. Agisoft Metashape has 81,222 tie points, while MicMac GUI has 2,476,115 tie points. Results from Agisoft Metashape were reached up to LOD 3, while MicMac GUI was not yet able to reach LOD 3. C2CD results on three-dimensional building models processed using the Agisoft Metashape majority point cloud showed a point cloud distance of 0 meters to the point cloud reference, while the MicMac on the front, left, and right sides of the building showed a point cloud gap of 0 meters to the reference point cloud, except on the rear where there is a distance between point clouds of about 0.210 meters to 0.630 meters against the point Cloud reference. Surface density models of three-dimensional buildings processed using Agisoft Metashape have 1,310.161 cloud points, and MicMac results have 1,600.529 cloud points. Processing on Agisoft Metashape old processing was completed within 16 minutes and 24 seconds, and on the older MicMac GUI processing was completed in 1 hour and 16 minutes, 26 seconds.
