Systems and Methods for Measuring Spectra of Skin and Other Objects and Materials and Making Predictions Based Thereon

摘要

Systems and methods for measuring spectra and other optical characteristics such as colors, translucence, gloss, and other characteristics of objects and materials such as skin. Instruments and methods for measuring spectra and other optical characteristics of skin or other translucent or opaque objects utilize an abridged spectrophotometer and improved calibration/normalization methods. Improved linearization methods also are provided, as are improved classifier-based algorithms. User control is provided via a graphical user interface. Product or product formulations to match the measured skin or other object or to transform the skin or other object are provided to lighten, darken, make more uniform and the like.

主权项

1. An apparatus for measuring optical properties of skin, comprising:
a spectrometer and a light source under control of a processing circuit; an optical cavity into which illumination from the light source is provided, wherein the cavity has an opening for illuminating a portion of the skin to be measured; a calibration/normalization reference having a surface for positioning such that the opening illuminates the calibration/normalization reference; a storage circuit coupled to the processing circuit that stores linearization coefficients and spectral data for the calibration/normalization reference and stores data for a classifier prediction algorithm; a display under control of the processing circuit; and a wireless module under control of the processing circuit; wherein the processor controls the display of control information on the display; wherein, in response to user activation based on the displayed control information, a measurement of the calibration/normalization reference is made and stored in the storage circuit; wherein, in response to user activation based on the displayed control information, a measurement of a portion of the skin is measured via the opening; wherein, based on the stored linearization coefficients and stored spectral data, spectral information for the measured portion of the skin is generated; wherein, based on the spectral information generated for the measured portion of the skin and based on the stored data for a classifier prediction algorithm, a particular one of a plurality of skin-applied products is predicted; wherein, under control of the processor, data indicative of the predicted particular one of the plurality of skin-applied products is transmitted remotely to a centralized resource for storage and/or subsequent processing.
