VIRTUAL MASK FITTING SYSTEM

摘要

Apparatus and associated methods relate to determining a fit-quality metric for a mask/face combination based upon a calculated dead-space volume between a virtual mask and a virtual face virtually aligned so as to create an integrity seal circumscribing a mouth and nose region. In an illustrative embodiment, an interactive virtual fitting system may receive a three-dimensional (3D) virtual face associated with a person. The system may retrieve 3D models of various respirators selected by user determined criteria. The system may then compute a fit-quality metric for each of the retrieved 3D models. The potential wearer may then be presented with the metrics for review. The potential wearer may select a respirator based upon these computed metrics. A virtual fitting of many respirators may advantageously reduce the time needed for selecting a properly fitting respirator while simultaneously ensuring that the selected respirator may be comfortable and well fitting.

主权项

1. A Graphical User Interface (GUI) program tangibly embodied in a computer readable medium and containing instructions that, when executed, cause a processor to perform operations to calculate a dead-space volume, the operations comprising:
receiving a three-dimensional facial model corresponding to a face of a person; retrieving, from data memory locations, a three-dimensional mask model that includes a contacting interface configured to provide an integrity seal continuously circumscribing a nose and mouth region of the face; superimposing the retrieved mask model onto the received facial model; calculating a dead-space volume circumscribed by the contacting interface and located between the received facial model and the retrieved mask model when superimposed onto the received facial model; associating a fit-quality metric with the calculated dead-space volume; sending, for display on the display device, indicia representative of the associated fit-quality metric and indicia representative of the calculated dead-space volume.
