Assessment of Cranial Deformation Indices by Automatic Smartphone-Based Photogrammetric Modelling

Abstract: This paper presents research carried out to assess the accuracy of a fully automatic smartphone-based photogrammetric solution (PhotoMeDAS) to obtain a cranial diagnostic based on the 3D head model. The rigorous propagation of the coordinate measurement uncertainty to the infant’s derived cranial deformation indices is demonstrated. The cranial anthropometric parameters and cranial deformation indices that PhotoMeDAS calculates automatically were analysed based on the estimated accuracy and uncertainty. To obt… Show more

“…PhotoMeDAS uses a coordinate system where the y-axis is defined by both preauricular points, the x-axis is defined by half of the preauricular points and the frontal point, and the z-axis is such that a right-hand coordinate system is formed [13].…”

“…1, Table 1). 3D body models facilitate growth and development assessment by generating accurate measurements and tracking changes over time, enabling early detection and intervention for potential issues, such as cranial deformation 36 . Moreover, these models aid diagnosis and treatment of medical conditions by simulating internal organs 37 , thus enhancing visualization and comprehension of conditions like congenital heart defects and contributing to improved surgical planning and outcomes.…”
