Identifying the correct size of a full facepiece respirator for an individual requires a significant degree of skill. Furthermore, the fit assessment procedure is time consuming due to the series of tasks required to calculate the fit factor, a measure of the quality of fit. The Chemical and Biological Defense (CBD) program needs a quicker, less manually intensive, and reliable method to select the correct respirators for individuals and approximate the fit factor. Technology Solution Experts, Inc. proposes to develop an advanced mobile application that, with 2D images of a subject's head as inputs, will transform a digital 3D headform to match the shape of the subject's head. TSE's approach will process and analyze 2D images to identify key anthropometric landmarks, enabling the accurate and realistic transformation of the 3D headform. The resulting head model can then be used in simulation to assess fit.
