A mobile device for measuring reflectance properties of a surface includes a first imaging device comprising an image sensor and a lens characterized by an optical axis; a first illumination source having an optical axis disposed at an angle of 45° with respect to the first imaging device lens' optical axis; a second imaging device comprising an image sensor and a lens characterized by an optical axis; and a second illumination source having an optical axis intersecting the first imaging device lens' optical axis where the first illumination source intersects the first imaging device lens' optical axis, the optical axes of the first imaging device and the second illumination source defining a second measurement plane. The mobile device further comprises a computer processor and a non-volatile memory comprising computer-readable instructions to acquire data from the first and second imaging devices and derive reflectance information of the surface of interest. 160006500.
