System and method for measuring pupillary distance and uses thereof

A non-transitory computer readable medium having computer-executable instructions embodied thereon, wherein, when executed by a processor, the computer-executable instructions cause the processor to:

• obtain, from at least one camera, a first 2D image and a corresponding 3D depth map of a face of a subject;
• determine pupil localization information using the first 2D image and corresponding 3D depth map;
• refine one or more pupil locations based on the pupil localization information using a convolution with one or more kernels and one or more 2D center-surround filters;
• determine one or more pupil center coordinates;
• and
• calculate the PD of the subject between centers of each pupil.

A pupillary distance (“PD”) system, comprising:

• a mobile device, comprising:
• at least one camera;
• memory storing information associated with images and information obtained from the at least one camera;
• and
• a processor configured to:
• obtain, from the at least one camera, a 2D image and a corresponding 3D depth map of a face of a subject;
• determine pupil localization information using the 2D image and corresponding 3D depth map;
• refine one or more pupil locations based on the pupil localization information using a convolution with one or more kernels and one or more 2D center-surround filters;
• determine one or more pupil center coordinates;
• and
• calculate the PD between centers of each pupil of the subject.
