Abstract

Pemodelan tiga dimensi (3D) objek ikonik memerlukan data yang mampu merepresentasikan detail secara lengkap dan akurat. Penelitian ini bertujuan menganalisis kualitas model 3D hasil integrasi foto udara dan foto terestris dengan pendekatan Structure from Motion (SfM) pada Monumen Simpang Lima Gumul (SLG), Kediri. Akuisisi data dilakukan menggunakan DJI Mavic 3 Enterprise dengan kombinasi citra nadir dan oblique, serta kamera DSLR Nikon D7000 dengan fotogrametri jarak dekat. Pengolahan data dilakukan dalam satu chunk terintegrasi untuk menghasilkan model 3D bertekstur. Evaluasi kualitas model meliputi analisis Level of Detail (LoD), analisis visual menggunakan pendekatan confusion matrix dan normalized cross correlation, serta analisis geometrik melalui uji paired t-test, perbandingan dimensi, dan analisis point cloud. Hasil menunjukkan bahwa model telah memenuhi standar LoD 3. Ketelitian geometrik model integrasi diperoleh sebesar RMSEX 0,026 m, RMSEY 0,028 m, dan RMSEZ 0,039 m, sedangkan model foto udara sebesar RMSEX 0,020 m, RMSEY 0,028 m, dan RMSEZ 0,037 m. Secara visual, model integrasi memiliki kualitas lebih baik dengan nilai metrik confusion matrix dan cross correlation lebih tinggi dibandingkan model foto udara. Uji paired t-test menunjukkan tidak terdapat perbedaan signifikan pada komponen horizontal, namun terdapat perbedaan pada komponen vertikal. Perbandingan dimensi menghasilkan RMSE sebesar 0,021 m pada model integrasi dan 0,030 m pada model foto udara. Integrasi foto udara dan foto terestris meningkatkan kualitas visual dan kelengkapan detail, namun tidak memberikan peningkatan signifikan pada ketelitian geometrik.

Three-dimensional (3D) modeling of iconic objects requires data capable of representing details accurately and comprehensively. This study aims to analyze the quality of 3D models generated from the integration of aerial and terrestrial photographs using the Structure from Motion (SfM) approach at the Simpang Lima Gumul Monument (SLG), Kediri. Data acquisition was conducted using a DJI Mavic 3 Enterprise UAV with nadir and oblique imagery, as well as a Nikon D7000 DSLR camera through close-range photogrammetry. Data processing was performed within a single integrated chunk to produce a textured 3D model. Model quality evaluation included Level of Detail (LoD) analysis, visual assessment using a confusion matrix approachand normalized cross correlation, and geometric analysis through a paired t-test, dimensional comparison, and point cloud analysis. The results indicate that the generated model meets the LoD 3 standard. The geometric accuracy of the integrated model achieved RMSEX of 0.026 m, RMSEY of 0.028 m, and RMSEZ of 0.039 m, while the UAV-only model achieved RMSEX of 0.020 m, RMSEY of 0.028 m, and RMSEZ of 0.037 m. Visually, the integrated model demonstrates better quality, with higher confusion matrix metrics and cross-correlation values compared to the aerial-photo-only model. The paired t-test results indicate no significant difference in the horizontal components, but a significant difference in the vertical component. Dimensional comparison yielded an RMSE of 0.021 m for the integrated model and 0.030 m for the UAV-only model. Therefore, the integration of aerial and terrestrial photographs significantly improves visual quality and detail completeness but does not provide a significant improvement in overall geometric accuracy.
