Measurement apparatus, information processing apparatus, information processing method, and storage medium

An information processing apparatus that processes information of an intensity distribution of reflected light from a surface, the reflected light being obtained by obliquely irradiating the surface with light, comprising:

• a first processing unit configured to determine a BRDF of the surface based on the information;
• a second processing unit configured to generate a first image representing the determined BRDF as a two-dimensional distribution and a second image representing a one-dimensional distribution obtained by projecting the two-dimensional distribution of the determined BRDF in a predetermined direction;
• and
• an output unit configured to output the first image and the second image to a display unit,
• wherein the second processing unit is configured to generate the first image representing the BRDF as the two-dimensional distribution in which an ordinate axis and an abscissa axis are two directions respectively orthogonal to an optical axis of specular light.

An information processing method of processing information of an intensity distribution of reflected light from a surface, the reflected light being obtained by obliquely irradiating the surface with light, characterized by comprising:

• a first step of determining a BRDF of the surface based on the information;
• a second step of generating a first image representing the determined BRDF as a two-dimensional distribution and a second image representing a one-dimensional distribution obtained by projecting the two-dimensional distribution of the determined BRDF in a predetermined direction;
• and
• a third step of outputting the first image and the second image to a display unit,
• wherein the second step generates the first image representing the BRDF as the two-dimensional distribution in which an ordinate axis and an abscissa axis are two directions respectively orthogonal to an optical axis of specular light.
