Abstract

Perkembangan teknologi LiDAR membuka metode baru untuk menganalisis struktural bangunan. Terrestrial Laser Scanner (TLS) menawarkan akurasi tinggi namun dengan biaya yang relatif mahal, sedangkan Mobile Laser Scanner (MLS) memberikan solusi yang lebih ekonomis dengan akurasi yang memadai. Penelitian ini membandingkan kinerja MLS dan TLS dalam pemodelan 3D bangunan. Masjid Manarul Ilmi ITS dipilih karena keunikan desain atap limas segi empat khas budaya Jawa. Georeferencing dilakukan menggunakan Ground Control Points (GCP) yang diukur secara terestris dengan Total Station. Hasil visualisasi menunjukkan bahwa densitas point cloud MLS lebih rendah dibandingkan TLS, sehingga detail visualnya lebih renggang. Namun secara geometris, MLS tetap mampu mencapai tingkat akurasi yang memadai. Nilai RMSEXYZ TLS tercatat sebesar 0,020 m, sedangkan RMSEXYZ MLS sebesar 0,063 m. Lalu, untuk uji panjang segmen RMSE TLS sebesar 0,015 m, dan MLS sebesar 0,55m. Secara keseluruhan, TLS menghasilkan point cloud sebanyak 417.603.669 titik, sedangkan MLS menghasilkan 182.466.842 titik. Kerapatan MLS yang lebih sedikit juga membuat waktu pengolahan data menjadi lebih singkat. TLS memerlukan waktu 18 menit 53 detik untuk ekspor data, namun MLS membutuhkan waktu 8 menit 42 detik.
==================================================================================================================================
The advancement of LiDAR technology has introduced new methods for building structural analysis. Terrestrial Laser Scanners (TLS) offer high accuracy but are relatively costly, whereas Mobile Laser Scanners (MLS) provide a more economical solution with sufficient accuracy. This study compares the performance of MLS and TLS in 3D building modeling. The Manarul Ilmi Mosque at ITS was selected due to the uniqueness of its pyramid-shaped roof, which reflects traditional Javanese architecture. Georeferencing was carried out using Ground Control Points (GCPs) measured terrestrially with a Total Station. Visualization results indicate that the point cloud density produced by MLS is lower than that of TLS, resulting in less detailed visual representations. However, geometrically, MLS is still capable of achieving an adequate level of accuracy. The recorded RMSEXYZ for TLS was 0.020 m, while for MLS it was 0.063 m. Then, for the segment length RMSE test, the TLS was 0.015 m, and the MLS was 0.55 m. Overall, TLS generated a point cloud of 417,603,669 points, whereas MLS produced 182,466,842 points. The lower density of MLS data also contributed to a shorter processing time. TLS required 18 minutes and 53 seconds to export the data, while MLS completed the export in 8 minutes and 42 seconds.
