METHOD AND SYSTEM TO ASSESS TEETH SHADE IN AN UNCONTROLLED ENVIRONMENT

METHOD AND SYSTEM TO ASSESS TEETH SHADE IN AN UNCONTROLLED ENVIRONMENT

A method (300) for characterizing color information about a tooth, comprising: (i) projecting (320) at least one predetermined color pattern (400); (ii) obtaining (330), using an imager (10), one or more images (90) each containing both a projected first predetermined color pattern (400) and at leas...

Zusammenfassung:A method (300) for characterizing color information about a tooth, comprising: (i) projecting (320) at least one predetermined color pattern (400); (ii) obtaining (330), using an imager (10), one or more images (90) each containing both a projected first predetermined color pattern (400) and at least a portion of a user's mouth (500); (iii) automatically identifying (340) by a controller (30), from the obtained one or more images, one or more teeth (510) in the at least a portion of the user's mouth (500( ); (iv) comparing (350) an imaged predetermined color pattern to a corresponding projected predetermined color pattern; and (v) extracting (360) by the controller, based on the outcome of the comparison, color information about the one or more identified teeth (510).
