Identitas seseorang dapat dibangun berdasarkan wajah. Oleh karena itu, wajah banyak digunakan diberbagai token otentikasi seperti KTP, paspor dan SIM. Fotogrametri jarak dekat merupakan salah satu bidang penerapan fotogrametri yang dapat digunakan untuk perekaman objek dengan jarak kurang dari 100 meter. Fotogrametri jarak dekat dapat dimanfaatkan dalam pemodelan 3D bangunan, kendaraan, jembatan maupun forensik. Pada penelitian ini, metode fotogrametri jarak dekat digunakan untuk pemodelan 3D wajah manusia dengan kamera digital non metrik. Kamera yang digunakan harus melalui proses kalibrasi untuk mengetahui parameter internal kamera. Proses kalibrasi dan pengolahan data dalam tugas akhir ini menggunakan perangkat lunak PhotoModeler Scanner v.7 2013. Tahap pemodelan bangunan terdiri dari marking dan referencing, proses hitungan dan pembuatan model 3D, dan visualisasi model 3D. Data yang digunakan adalah data foto yang diambil secara keseluruhan mengelilingi wajah objek manusia. Hasil akhir dalam penelitian ini adalah model 3 dimensi wajah manusia. Pengujian hasil pengolahan model 3D dilakukan dengan analisis perbandingan selisih jarak dan analisis visual oleh dokter ahli forensik. Dari hasil pengolahan data, didapat nilai RMS foto terbesar adalah 1,275 piksel. Hasil statistik menunjukkan bahwa hubungan variabel hasil Photomodeler memiliki korelasi/keterkaitan secara positif dengan variabel hasil ukuran forensik dengan hasil nilai sig 0,000000513922 memenuhi tingkat signifikansi 5%. Potensial akurasi pemrosesan model 3D masih rendah yaitu nilai 2 ( Low ). Berdasarkan hasil perbandingan jarak 3D, menunjukkan bahwa pemodelan memiliki nilai rata-rata selisih sebesar 1,066 mm, dengan nilai deviasi sebesar ±1,323 mm. Hal ini menunjukkan bahwa tidak terdapat perbedaan yang signifikan antara pengukuran hasil model dan hasil pengukuran meteran.

A person's identity can be recognized based on the face. Therefore, the face is widely used in various authentication tokens such as ID cards, passports and driver's license. Fotogrametri close range is one of the areas of application of photogrammetry. Close range photogrammetry can be used for recording the object within less than 100 meters. Close range photogrammetry is typically used in 3D modeling of buildings, vehicles, bridges and forensics. In this study, close-range photogrammetry method used for 3D modeling of human faces with non-metric digital camera. The camera is used to go through the calibration process to determine the internal parameters of the camera. The Process calibration and data processing in this study use software PhotoModeler Scanner v.7 2013. The building modeling stage consists of marking and referencing, the count process and 3D model creation and visualization of 3D models. The data used is the data of photos taken as a whole around the face of a human object . The final result in this study is three-dimensional model of a human face. The test results of the processing of 3D models performed by a comparative analysis of distances and visual analysis by forensic specialists. From the data processing, obtained the RMS value of the largest photo was 1.275 pixels. The statistical results showed that the relationship Photomodeler outcome variables have a correlation / relationship positively with variable results with the results of forensic size sig .000000513922 meet the 5% significance level. Potential accuracy of processing the 3D model still lower that the value of 2 (Low). Based on the comparison results within the 3D modeling has showed that the average value of a difference is 1.066 mm, with a deviation of ± 1.323 mm. This shows that there is no significant difference between the measurement results of the model and meter measurement results.
