Abstract

Teknologi fotogrametri rentang dekat terbaru yaitu scanner telah digunakan sebagai teknik survei model 3D yang sering digunakan dikarenakan oleh kepraktisan dan kualitas hasilnya. Namun harga perangkat yang terkait tidak dapat dibeli oleh sebagian besar orang maupun instansi, sehingga pada penelitian ini dilakukan pengujian hasil model 3D dari perangkat DSLR (Digital Single Lens Reflex) sebagai alternatif baru berbiaya rendah. Dilakukan akuisisi dari perangkat DSLR dan pengolahan dengan perangkat lunak AliceVision Meshroom dan dilakukan pengujian validasi dengan uji geometrik posisi dan jarak dengan ICP (Independent Check Point) dan T-Test. Dihasilkan model DSLR yang hanya dapat memodelkan bagian badan bangunan candi saja dengan detail relief yang cukup tinggi dan pada uji validasi didapatkan bagian akurasi geometrik posisi masuk ke dalam kelas UDLOA Lower Range dengan CE90 sebesar 0,0904 dan LE90 sebesar 0,0924 serta pada bagian akurasi geometrik jarak masuk ke dalam kelas LOA30 Lower Range dengan jumlah error sebesar 1,1937 m dan rata-rata error sebesar 0,0173 m. Dapat disimpulkan bahwa metode DSLR tidak direkomendasikan sebagai metode pemodelan 3D berbiaya rendah dikarenakan oleh model bangunan bagian atap yang tidak berhasil dimodelkan.

Abstract

Existing scholarly literature on the Gaussian Splatting algorithm has predominantly concentrated on improving the rendering and reconstruction of three-dimensional objects, as well as exploring its applications in various academic disciplines, such as medicine, robotics, and mapping, while being limited to local coordinate systems. This study describes the development of a 3D scene modeled using the Gaussian Splatting algorithm, featuring accurate distance and position geometry based on Three JS. The developed 3D scene was then evaluated with precise position and distance coordinates in the field and compared to the established SfM-MVS (Structure from Motion-Multi View Stereo) algorithm. The findings demonstrate that the proposed development successfully generated Three JS-based 3D scenes with global coordinate compatibility utilizing the Gaussian Splatting algorithm, achieving the same level of position and distance accuracy as the SfM-MVS algorithm, with a 95% confidence interval using T-Test. This research concludes that the developed approach is successful and can be further expanded for various scientific fields that require accurate position and distance information using Gaussian Splatting Algorithm.
