System and Method of Obtaining Fit and Fabrication Measurements for Eyeglasses Using Simultaneous Localization and Mapping of Camera Images

A method of obtaining at least some measurements needed to correctly fabricate lenses for a person, said method comprising the steps of:

• providing eyeglass frames into which said lenses are to be set;
• providing a smartphone having a camera, an autofocus system, and a processor, wherein said processor runs application software;
• imaging the person wearing said eyeglass frames from a first camera position and from at least one subsequent camera position, therein producing images having differing perspectives, wherein said first camera position and said at least one subsequent camera position are at camera distances measurable by said autofocus system, and wherein said camera distances are in a first measurement scale;
• utilizing said application software to identify common measurement points within at least some of said images, wherein at least some of said common measurement points undergo positional changes between said images having said differing perspectives;
• utilizing said application software to identify said positional changes in said common measurement points between at least some of said images and said camera distances of first camera position and said at least one subsequent camera position to map three dimensional coordinates for said measurement points in said first measurement scale;
• and
• utilizing said application software to calculate fabrication measurements between said three dimensional coordinates in said first measurement scale.

• providing eyeglass frames into which said lenses are to be set;
• providing an electronic device having a camera, an autofocus system, and a processor, wherein said processor runs application software;
• imaging said eyeglass frames while being worn from a first camera position and from at least one subsequent camera position, therein producing images having differing perspectives, wherein said first camera position and said at least one subsequent camera position are at camera distances measurable by said autofocus system, and wherein said camera distances are in a first measurement scale;
• identifying said common measurement points within at least some of said images utilizing said application software, wherein at least some of said common measurement points undergo positional changes between said images having said differing perspectives;
• identifying said positional changes in said common measurement points between at least some of said images and said camera distances of said first camera position and said at least one subsequent camera position to map three dimensional coordinates for said measurement points in said first measurement scale;
