Abstract

Perkembangan teknologi geospasial mendorong kebutuhan terhadap data spasial tiga dimensi (3D) untuk berbagai kebutuhan. Model 3D dinilai mampu merepresentasikan kondisi riil suatu objek secara presisi, sehingga menjadi alat bantu penting dalam proses perencanaan. Penelitian ini bertujuan untuk menganalisis hasil integrasi data point cloud dari Terrestrial Laser Scanner (TLS) dan Airborne Laser Scanner (ALS) dalam pembuatan model 3D Gedung Rektorat Institut Teknologi Sepuluh Nopember. Hasil akuisisi dan pengolahan data dari Terrestrial Laser Scanner diperoleh nilai mean bundle error sebesar 0,004 meter dan pada GCP diperoleh RMSE_x sebesar 0,005 meter, RMSE_y sebesar 0,013 meter, dan RMSE_z sebesar 0,009 meter. Pada data ALS diperoleh hasil average altitude difference sebesar 0,037 meter dan RMSE sebesar 0,048 meter. Integrasi dari data point cloud TLS dan ALS mampu merepresentasikan geometri objek secara menyeluruh baik dari bentuk eksterior maupun struktur interior bangunan dengan hasil registrasi yang menunjukkan nilai RMSE_x sebesar 0,012 meter, RMSE_y sebesar 0,015 meter, dan RMSE_z sebesar 0,008 meter. Hal ini sesuai tingkat akurasi tinggi dan sesuai dengan standar pemodelan tiga dimensi berdasarkan Open Geospatial Consortium pada LOD 4 sebesar 0,200 meter. Hasil uji akurasi geometrik perbandingan panjang model 3D dengan data panjang eksisting gedung menunjukkan nilai RMSE sebesar 0,042 meter. Hal ini menunjukkan ketelitian geometris yang tinggi dan telah memenuhi standar ketelitian Level of Detail (LOD) 4. Pada hasil visualisasi model 3D yang telah dihasilkan telah memenuhi spesifikasi semua kriteria LOD 3 dan sebagian LOD 4, mencakup representasi struktur bangunan secara lengkap dari sisi eksterior maupun interior

The development of geospatial technology encourages the need for three-dimensional (3D) spatial data for various needs. 3D models are considered capable of representing the real conditions of an object with precision, so they become an important tool in the planning process. This research aims to analyze the results of the integration of point cloud data from Terrestrial Laser Scanner (TLS) and Airborne Laser Scanner (ALS) in creating a 3D model of the Rectorate Building of Sepuluh November Institute of Technology. The results of data acquisition and processing from Terrestrial Laser Scanner obtained a mean bundle error value of 0,004 meters and on GCP obtained RMSE_x of 0,005 meters, RMSE_y of 0,013 meters, and RMSE_z of 0,009 meters. On ALS data, the average altitude difference is 0.037 meters and RMSE is 0.048 meters. The integration of TLS and ALS point cloud data is able to represent the geometry of the object as a whole both from the exterior shape and interior structure of the building with registration results showing an RMSE_x value of 0,012 meters, RMSE_y of 0,015 meters, and RMSE_z of 0,008 meters. This corresponds to a high level of accuracy and is in accordance with the three-dimensional modeling standard based on the Open Geospatial Consortium at LOD 4 of 0,200 meters. The geometric accuracy test results of the 3D model length comparison with the existing building length data show an RMSE value of 0,042 meters. This shows high geometric accuracy and has met the Level of Detail (LOD) 4 accuracy standard. The visualization results of the 3D model that have been produced have met the specifications of all LOD 3 and partially LOD 4 criteria, including a complete representation of the building structure from the exterior and interior.
