Abstract
Pemodelan 3D cagar budaya seperti Candi Tikus umumnya menggunakan metode Structure from Motion (SfM) dan Multi-View Stereo (MVS). Namun, metode ini menghasilkan model dengan ukuran file sangat besar, rendering lambat, serta kesulitan dalam merekonstruksi permukaan reflektif dan objek tipis. Penelitian ini bertujuan mengevaluasi penerapan metode 3D Gaussian Splatting (3DGS) menggunakan data fotogrametri udara (UAV) dan terestrial pada kondisi lingkungan kering dan tergenang air, serta membandingkannya dengan metode SfM/MVS. Evaluasi dilakukan secara kualitatif terhadap kualitas visual dan secara kuantitatif melalui analisis Cloud-to-Cloud (C2C) dan Root Mean Square Error (RMSE) dimensi linier yang divalidasi menggunakan Roll Meter pada 7 segmen pengukuran lapangan. Hasil penelitian menunjukkan bahwa 3DGS unggul secara visual dalam memodelkan permukaan reflektif dan elemen kompleks tanpa data void, dengan ukuran file lebih kecil (543-1.038 MB vs 1.993-3.467 MB pada SfM/MVS) dan kecepatan rendering 4-6 kali lebih tinggi (92-98 fps). Pada kondisi kering, ketelitian geometrik 3DGS sebanding dengan SfM/MVS (RMSE 1,36 cm vs 1,18 cm, C2C Mean Distance 0,183 m). Namun pada kondisi tergenang terjadi anomali akurasi (RMSE 18,5 cm, C2C Mean Distance 0,229 m) akibat kegagalan konvergensi Gaussian pada area reflektif. Secara keseluruhan, 3DGS terbukti menjadi alternatif yang efisien dan fotorealistik untuk pelestarian digital dan visualisasi interaktif cagar budaya secara real-time.

3D modeling of cultural heritage such as Candi Tikus commonly employs Structure from Motion (SfM) and Multi-View Stereo (MVS) methods. However, these methods produce models with very large file sizes, slow rendering performance, and difficulties in reconstructing reflective surfaces and thin objects. This study aims to evaluate the application of the 3D Gaussian Splatting (3DGS) method using aerial (UAV) and terrestrial photogrammetry data under both dry and waterlogged environmental conditions, and to compare it with the SfM/MVS method. The evaluation was conducted qualitatively through visual quality assessment and quantitatively through Cloud-to-Cloud (C2C) distance analysis and Root Mean Square Error (RMSE) of linear dimensions, validated using a tape measure on 7 field measurement segments. The results demonstrate that 3DGS exhibits significant visual advantages in modeling reflective surfaces and complex elements without generating data voids, with smaller file sizes (543-1,038 MB vs 1,993-3,467 MB for SfM/MVS) and rendering speeds 4-6 times higher (92-98 fps). Under dry conditions, the geometric accuracy of 3DGS is comparable to SfM/MVS (RMSE 1.36 cm vs 1.18 cm, C2C Mean Distance 0.183 m). However, under waterlogged conditions, accuracy anomalies occurred (RMSE 18.5 cm, C2C Mean Distance 0.229 m) due to Gaussian convergence failure on reflective surfaces. Overall, 3DGS proves to be an efficient and photorealistic alternative for digital preservation and real-time interactive visualization of cultural heritage.
