3D digital stereophotogrammetry: a practical guide to facial image acquisition
The use of 3D surface imaging technology is becoming increasingly common in craniofacial clinics and research centers. Due to fast capture speeds and ease of use, 3D digital stereophotogrammetry is quickly becoming the preferred facial surface imaging modality. These systems can serve as an unparalleled tool for craniofacial surgeons, proving an objective digital archive of the patient's face w...
متن کامل3D measurement of human face by stereophotogrammetry
Furthermore, for encoding the object shape a special illumination is adapted which maps a sequence of about 20 statistically generated patterns onto the object (see figure 1). Therefore, every point of the object surface is characterized by an individual sequence of intensity values. This approach makes it possible to use a single sensor element for allocating homologous points. It is not neces...
متن کاملComparison of Craniovertebral Angle of Students based on Gender and Field of Study Differences
Background: Since neck bears head’s weight, its abnormal position not only makes an inharmonious appearancebut also can cause musculoskeletal disorders. The aim of this study was to compare the craniovertebral (CV) angle of students based on their gender and field of study. Methods: In this descriptive study, 1017 students (511 female and 506 male students) of...
متن کاملEvaluation of reproducibility and reliability of 3D soft tissue analysis using 3D stereophotogrammetry.
In 3D photographs the bony structures are neither available nor palpable, therefore, the bone-related landmarks, such as the soft tissue gonion, need to be redefined. The purpose of this study was to determine the reproducibility and reliability of 49 soft tissue landmarks, including newly defined 3D bone-related soft tissue landmarks with the use of 3D stereophotogrammetric images. Two observe...
متن کامل3D analysis of facial morphology.
Dense surface models can be used to analyze 3D facial morphology by establishing a correspondence of thousands of points across each 3D face image. The models provide dramatic visualizations of 3D face-shape variation with potential for training physicians to recognize the key components of particular syndromes. We demonstrate their use to visualize and recognize shape differences in a collecti...
