Abstract
Perkembangan teknologi kamera smartphone pada saat ini semakin maju, bahkan hampir menyamai kamera DSLR, dimana kamera DSLR sendiri sudah mulai digunakan dalam kegiatan fotogrametri jarak dekat. Dengan berkembangnya teknologi yang terdapat pada kamera smartphone, maka dari itu kamera smartphone dapat dijadikan pilihan pada kegiatan fotogrametri jarak dekat dalam hal pemodelan 3D.
Penelitian ini merupakan metode akusisi pemodelan tiga dimensi menggunakan tiga smartphone dengan level kamera yang berbeda, yaitu Redmi note 3 Pro, Samsung A5(2017), dan iPhone 7 Plus. Kemudian dilakukan kalibrasi laboratorium menggunakan papan kolimator berupa papan catur dengan ukuran 3cm x 3cm pengambilan foto dilakukan dari berbagai sudut dengan total gambar 12 foto. Data yang dihasilkan berupa 7 parameter IOP (Interior Orientation Parameter). Kalibrasi tersebut dilakukan menggunakan software yang terdapat pada Matlab. Setelah itu dilakukan pengambilan data berupa poligon untuk koordinat titik kontrol, Ground Control Point (GCP), dan Independent Control Point (ICP) menggunakan Electronic Total Station. Dari pengambilan data tersebut didapatkan 4 titik kontrol, 7 buah GCP pada objek untuk georeferencing, dan 29 titik ICP yang tersebar pada objek yang sudah diberi tanda berupa marker. Pemodelan dilakukan dengan bantuan software pengolahan foto dengan metode Structure From Motion (SfM). Analisis yang dilakukan yaitu membandingkan ICP pada Model 3D setiap kamera dengan menghitung RMSE.
Hasil penelitian ini menunjukkan bahwa kamera smartphone mampu membentuk 3 dimensi. Dari hasil analisis yang didapat dari ketiga model memiliki RMSE sebesar <0.5 meter dimana dengan toleransi tersebut model 3D masuk dalam kategori LoD3. Untuk perbandingan ICP yang diuji didapatkan hasil yang tidak terlalu signifikan karena perbedaan nilai yang didapat tidak terlalu besar. Dari uji t setiap kamera smartphone menunjukan bahwa smartphone iPhone 7 Plus memiliki performa yang tinggi disusul dengan Samsung A5 (2017) dan terakhir Redmi Note 3 Pro. Dengan nilai sebesar: Samsung A5 (2017) 87.35%, iPhone 7 plus 93.10%, dan Redmi Note 3 Pro 83.90%.

The development of smartphone camera technology at this time is more advanced, even almost catching up to DSLR cameras performance, where DSLR cameras themselves have started to be used in close range photogrammetry activities. With the development of technology contained in the smartphone camera, it can be selected on the activities of close-range photogrammetry in terms of 3D modeling.
In this study, will acquire 3D modeling using three smartphones with different camera levels, which are Redmi note 3 Pro, Samsung A5 (2017), and iPhone 7 Plus.A laboratory calibration is then performed using collimator board in the form of a chessboard with a size of 3cm x 3cm taking photos that are taken from various angles with a total of 12 images. Calibration is done using the software contained in Matlab that deliver 7 parameters data of IOP (Interior Orietation Parameter). Afterwards, data is taken in the form of polygons for control point coordinates, Ground Control Point (GCP), and Independent Control Point (ICP) using Electronic Total Station. The resulting data consist of 4 point control, 7 GCP on the object for geoferencing, and 29 ICP points placed on the marked object. The modeling can be done with the help of photo processing software with Structure From Motion (SfM) method. The analysis performed comparing ICP to 3D models on each camera by computing each RMSE.
The result of this study indicates that the smartphone camera is able to provide the model in accordance with the actual object. From the analysis result for all three models obtained RMSE <0,5m, with that tolerance, the 3D model are caterogized as LoD3 category. From the comparison of ICP tested, the results obtained are not very significant because the difference between each value wasn’t too large. Based on t-test of each Smartphone camera showed if iPhone 7 Plus has the best performance followed by Samsung A5 (2017) and lastly Redmi Note 3 Pro. With the following value: Samsung A5 (2017) 87.35%, iPhone 7 plus 93.10%, and Redmi Note 3 Pro 83.90%.
