Systems and methods for characterizing spectral reflectance of real world objects

A method comprising:

• receiving first image data associated with a first image of an object illuminated at a first wavelength and captured by a camera at the first wavelength, the first image data including first pixel data for a first pixel of the first image and second pixel data for a second pixel of the first image;
• calculating a first reflectance value for the first pixel using the first pixel data;
• calculating a second reflectance value for the second pixel using the second pixel data;
• and
• generating, using the first reflectance value and the second reflectance value, a first reflectance distribution of the object.

A non-transitory computer-readable medium storing computer-executable instructions, that when executed by at least one processor, cause the at least one processor to:

• receive first image data associated with a first image of an object illuminated at a first wavelength and captured by a camera at the first wavelength, the first image data including first pixel data for a first pixel of the first image and second pixel data for a second pixel of the first image;
• calculate a first reflectance value for the first pixel using the first pixel data;
• calculate a second reflectance value for the second pixel using the second pixel data;
• and
• generate, using the first reflectance value and the second reflectance value, a first reflectance distribution of the object.
