Abstract

Pemodelan 3D ruangan memiliki peran penting di berbagai bidang seperti arsitektur, konstruksi, dan perencanaan ruang. Terrestrial Laser Scanner (TLS) dan Hand-held Mobile Laser Scanner (HMLS) berbasis smartphone merupakan dua metode utama dalam akuisisi data untuk pembuatan model 3D. Penelitian ini bertujuan untuk menganalisis akurasi geometris dan tingkat pengembangan model (Level of Development/LOD) hasil pemrosesan data point cloud TLS serta hasil akuisisi HMLS dengan pembanding pengukuran langsung menggunakan meteran. Lokasi penelitian dilakukan di Gedung Departemen Teknik Geomatika ITS dengan menggunakan dua instrumen berbeda, yaitu Terrestrial Laser Scanner Leica RTC360 dan Hand-held Mobile Laser Scanner berbasis smartphone Apple iPhone 14 Pro Max. Data point cloud hasil TLS selanjutnya diolah menjadi model 3D menggunakan perangkat lunak Autodesk Revit, sedangkan hasil automated indoor modeling dari HMLS diekspor menggunakan perangkat lunak SketchUp. Analisis dilakukan dengan menghitung nilai root mean square error (RMSE) antara model yang dihasilkan dan pengukuran langsung menggunakan meteran. Selain itu, dilakukan juga analisis LOD untuk mengevaluasi kelengkapan informasi serta tingkat pengembangan model 3D. Hasil penelitian menunjukkan bahwa TLS memiliki akurasi geometris dengan nilai RMSE sebesar 0,016 m, sedangkan HMLS memiliki nilai RMSE sebesar 0,058 m. Model 3D hasil TLS memenuhi parameter untuk LOD 300, sementara model HMLS dikategorikan memenuhi parameter untuk LOD 200.

3D room modeling has an important role in various fields such as architecture, construction, and spatial planning. Terrestrial Laser Scanner (TLS) and smartphone-based Hand-held Mobile Laser Scanner (HMLS) are two primary methods for data acquisition in creating 3D models. This research aims to analyze the geometric accuracy and level of development (LOD) of 3D models generated from TLS point cloud data and HMLS acquisition, compared with direct measurements using a tape measure. The research was conducted at the Department of Geomatics Engineering Building, ITS, using two different instruments: the Terrestrial Laser Scanner Leica RTC360 and a Hand-held Mobile Laser Scanner based on the Apple iPhone 14 Pro Max. The TLS point cloud data was processed into a 3D model using Autodesk Revit software, while the automated indoor modeling results from HMLS were exported using SketchUp software. The analysis was performed by calculating the Root Mean Square Error (RMSE) value between the generated models and direct measurements using a tape measure. Additionally, an LOD analysis was conducted to evaluate the completeness of information and the development level of the 3D models. The results show that TLS has geometric accuracy with an RMSE value of 0.016 m, while HMLS has an RMSE value of 0.058 m. The 3D model from TLS meets the parameters for LOD 300, whereas the HMLS model is categorized as meeting the parameters for LOD 200.
