Systems and Methods of Using Labels for Evaluation of Produce and Other Foods

摘要

Attributes of vegetables or biologics are derived by use of color imaging sensors and relative spectral band analysis. Enabled smart phones or dedicated single pixel or focal plane instruments for crop applications to quickly report the biological condition of vegetables or other organics by providing an augmented view or relative quantification of RGB ratios of the inspected items. The RGB ratios are compared to RGB ratios of preprinted labels. The comparison yields information regarding the freshness and other attributes of the inspected item. Disclosed embodiments are well suited for analyzing the health and needs of living plants or crops. Ratios of observed wide band red, green and blue are compared on a relative basis. While food shopping, an enabled smart phone may view an agricultural product and use a preprinted RGB ratio label as a reference guide.

主权项

1. A method of comparing ratios of wideband spectral channel sum values of an agricultural product that can include but not limited to produce, poultry, fish, meat flowers, plants and crops, to wideband spectral channel summary ratios of a preprinted ratio label, in a manner to highlight calculated biological qualities detected on wideband image sensors, the method comprising the steps of:
a) obtaining one or more broadband digital images of the agricultural product, the digital images containing sensor wide broadband color values that may include red, green and blue channels (RGB) or other separation techniques; b) creating agricultural wideband spectral channel summary ratios from the wideband RGB values from a plurality of derivative formulas such as r/b, g/b, r/g wherein the ratios relate to both pure biological narrow band properties as well as sensor wideband sensitivity; c) creating the preprinted ratio label by using wideband spectral channel summary ratios mapped to the calculated biological qualities; and d) comparing and reporting wideband spectral channel summary ratio differences between the agricultural product's wideband spectral channel summary ratios to the wideband spectral channel summary ratios of the preprinted ratio label.
