Abstract

Dokumentasi aset infrastruktur kampus, seperti Gedung Teknik Informatika ITS, memerlukan representasi tiga dimensi (3D) yang presisi namun tetap mudah diakses. Metode rekonstruksi konvensional sering kali terkendala oleh beban komputasi tinggi saat rendering interaktif. Penelitian ini menerapkan metode 3D Gaussian Splatting (3DGS) untuk merekonstruksi eksterior dan sampel ruangan interior Gedung Teknik Informatika ITS, menghasilkan 13 model scene yang terdiri dari satu eksterior dan 12 ruangan interior. Akuisisi data dilakukan menggunakan drone untuk eksterior gedung serta perangkat genggam untuk ruangan interior, dengan input berupa rekaman video yang diproses menggunakan perangkat lunak Postshot. Perangkat lunak tersebut menangani estimasi geometri awal (Structure-from-Motion) hingga optimasi model Gaussian secara terintegrasi dalam satu pipeline internal. Hasil rekonstruksi kemudian diintegrasikan ke dalam platform visualisasi berbasis web yang dikembangkan menggunakan PlayCanvas Engine dengan format model Spatially Ordered Gaussians (.sog) dan dapat diakses secara publik melalui https://ifsplat.my.id. Hasil kuantitatif kualitas visual rekonstruksi dievaluasi menggunakan metrik PSNR, SSIM, dan LPIPS, sementara performa rendering dievaluasi menggunakan metrik Frames Per Second (FPS) pada dua perangkat dengan spesifikasi GPU yang berbeda. Hasil ini diharapkan mendukung digitalisasi aset kampus yang interaktif dan dapat diakses secara luas oleh civitas akademika.

Documentation of campus infrastructure assets, such as the ITS Informatics Engineering Building, requires a precise yet accessible three-dimensional (3D) representation. Conventional reconstruction methods are often constrained by high computational costs during interactive rendering. This research applies the 3D Gaussian Splatting (3DGS) method to reconstruct the exterior and selected interior rooms of the ITS Informatics Engineering Building, producing 13 scene models consisting of one exterior and 12 interior rooms. Data acquisition was carried out using a drone for the building exterior and a handheld device for the interior rooms, with video recordings as input processed using Postshot software. The software handles the initial geometry estimation (Structure-from-Motion) through Gaussian model optimization in an integrated internal pipeline. The reconstruction results were then integrated into a web-based visualization platform developed using the PlayCanvas Engine with the Spatially Ordered Gaussians (.sog) model format, publicly accessible via (https://ifsplat.my.id). The quantitative visual quality of the reconstruction was evaluated using PSNR, SSIM, and LPIPS metrics, while rendering performance was evaluated using Frames Per Second (FPS) metrics on two devices with different GPU specifications. These results are expected to support the interactive digitalization of campus assets, making them accessible to the wider academic community.
