Abstract

Penelitian ini bertujuan untuk membandingkan metode registrasi cloud to cloud dan target to target dalam pemodelan 3D Gedung Grha ITS indoor berbasis data Terrestrial Laser Scanner (TLS). Akuisisi data TLS dilakukan dengan resolusi medium dan overlap keseluruhan 70% yang menghasilkan 135 setup dan 135 link pada metode cloud to cloud serta 135 setup dan 134 link pada metode target to target. Selain itu, dilakukan akuisisi data GNSS metode statik radial untuk GCP 01 dan GCP 02, serta akuisisi data Total Station metode tachimetri untuk 1 titik bantu, 32 titik kontrol badan bangunan, dan 20 titik sampel panjang segmen bangunan. Pengolahan data TLS menghasilkan point cloud metode cloud to cloud dengan mean bundle error 0,003 m, error registrasi 0,003 m, dan error georeferencing 0,012 m, serta point cloud metode target to target dengan nilai mean bundle error 0,008 m, error registrasi 0,013 m, dan error georeferencing 0,007 m yang sudah memenuhi standar akurasi ASPRS <5 cm. Hasil pengolahan GNSS menunjukkan ketelitian koordinat GCP pada orde sentimeter, sedangkan data Total Station menghasilkan titik kontrol dan panjang segmen bangunan yang digunakan sebagai referensi geometri bangunan. Pemodelan tiga dimensi indoor dilakukan menggunakan point cloud hasil pengolahan TLS dan menghasilkan model keseluruhan yang memenuhi klasifikasi Level of Detail (LoD) 4. Hasil perbandingan menunjukkan bahwa metode cloud to cloud lebih unggul berdasarkan error registrasi, nilai RMSE, visualisasi model 3D, dan waktu pemrosesan. Keunggulan tersebut didukung oleh area overlap yang besar sehingga proses penyelarasan point cloud berlangsung optimal. Dengan demikian, metode registrasi cloud to cloud direkomendasikan untuk studi kasus Gedung Grha ITS indoor.

This study aims to compare the cloud-to-cloud and target-to-target registration methods in the indoor 3D modeling of the Grha ITS Building based on Terrestrial Laser Scanner (TLS) data. TLS data acquisition was conducted using medium resolution and an overall overlap of 70%, resulting in 135 setups and 135 links for the cloud-to-cloud method, and 135 setups and 134 links for the target-to-target method. In addition, GNSS data were acquired using the radial static method for GCP 01 and GCP 02, while Total Station data were collected using the tachymetric method for one auxiliary control point, 32 building control points, and 20 building segment length sample points. TLS data processing produced a cloud-to-cloud point cloud with a mean bundle error of 0.003 m, a registration error of 0.003 m, and a georeferencing error of 0.012 m. Meanwhile, the target-to-target point cloud yielded a mean bundle error of 0.008 m, a registration error of 0.013 m, and a georeferencing error of 0.007 m. Both methods satisfied the ASPRS accuracy standard of less than 5 cm. GNSS data processing indicated centimeter-level coordinate accuracy for the GCPs, while Total Station observations provided building control points and segment lengths used as references for building geometry. Indoor three-dimensional modeling was performed using the processed TLS point clouds and resulted in a complete model that met the Level of Detail (LoD) 4 classification. The comparison results indicate that the cloud-to-cloud method outperformed the target-to-target method in terms of registration error, RMSE values, 3D model visualization, and processing time. This advantage is supported by the large overlap area, which enabled optimal point cloud alignment during the registration process. Therefore, the cloud-to-cloud registration method is recommended for the indoor case study of the Grha ITS Building.
