Multiresolution and Displacement: Modifier Attribution to Enhance Realistic 3D Photogrammetry for Models of the Face

“…This study's intent was not to compare accuracy of physical anatomical reproductions from virtual 3D models, [5,6,11], as previous investigators have compared stereophotogrammetry methods with monoscopic photogrammetry through a smartphone method, and found no statistically significant difference between the two methods [14], The authors of the present study suggest a reproducible and predictable protocol for image capture when utilizing monoscopic photogrammetry [4,8]. In this study we defined a reproducible workflow for further processing of 3D models of the human face, using standardized protocols [7] and using native tools from graphic & computer science modifiers like multiresolution and displacement with OrtogOnBlender in order to achieve more realistic details and reproducible characteristics of skin.…”

“…In this study, we explored the computational capabilities of visualization and processing of the Add-On OrtogOnBlender for optimizing 3D models of faces. Our results demonstrated that this software functionality enables more efficient and high-quality rendering, modeling, visualization, and animation of volumetric data, significantly enhancing the output of 3D photogrammetry software [7,10,11]. Stereophotogrammetry, monoscopic photogrammetry and structured light processes can achieve a colored, volumetric model of the skin of faces with accuracy, reproducibility, and with proportional integrity.…”

“…The case of OrtogOnBlender is an add-on that combines most of the 3D technologies that could be useful for virtual surgery and prosthetic planning, since the data acquisition, 3D modeling up to prepare the model for 3D printing, like in surgical guide creations or like in PlusID methodology to create a prototype to optimize a final prosthesis [7]. In this study, we explored the computational capabilities of visualization and processing of the Add-On OrtogOnBlender for optimizing 3D models of faces.…”

“…Volunteer subjects accepted to take part of the study and were recruited for data capture of the face. Using an Android® smartphone (Asus Zenfone 2® Asus Inc., Taiwan-China), frontal face protocol of 26 total captures (13 captures & 2 heights) for monoscopic photogrammetry [7] was used to acquire 3D data of the faces of six (6) subjects of varying age and gender (mean age 46, range 27-68; 4 females, 3 males). "Plus ID (+ID)" workflow was followed.…”

Importance of Calibration of Photos Obtained by A Smartphone in Facial Prosthesis

“…This discrepancy in capturing the actual color of the patient's skin can lead to errors, with the prosthesis having to be remade, incurring higher material cost and a longer time to complete the work. These discrepancies may be even more important when 3D digital workflows, which include 3D models of faces obtained by optical resources, will evolve into color 3D printing for final facial prosthesis delivery, like the PlusID (+ID) methodology which uses smartphones and "UV maps" from monoscopic photogrammetry to obtain the color information of the face of the patient [11,12]. In view of the high cost of these instruments for accurate color capture, they are not widely used in rehabilitation centers, especially in those with fewer investments.…”
