摘要： An evaluation device includes a projector to project a pattern having an edge component onto an object, an imaging device to capture an image of the object, a reflective-property correction unit to correct an amount of change in shape of a virtual image of the pattern reflected in the object, using reflective-property data of a surface of the object, and an evaluation-value calculator to evaluate image clarity of the surface of the object based on the corrected amount of change. A computer-readable non-transitory recording medium storing a program for causing a computer to execute a method. The method includes correcting an amount of change in shape of a virtual image of the pattern reflected in the object based on image data that is obtained by capturing an object onto which a pattern having an edge component is projected, using reflective-property data of a surface of the object.

摘要： A texture evaluation apparatus includes a projector, an imager, and an evaluator. The projector is configured to project a two-dimensional pattern having an edge element onto an object. The imager is configured to capture an image of a surface of the object. The evaluator is configured to calculate an amount of shape change of a virtual image of the two-dimensional pattern in the image, and evaluate texture of the object based on the amount of shape change and sensory evaluation information obtained in advance.

摘要： A color measurement apparatus includes at least one illuminator, an imager, and circuitry. The circuitry is configured to normalize each pixel included in an imaging region of one of the spectral reflectance images of the measurement target irradiated with light at a specific illumination angle of the plurality of illumination angles, with one of the spectral reflectance images of the reference object irradiated with light at the specific illumination angle, for each of the plurality of illumination angles so as to generate normalized spectral reflectance images of the measurement target. The circuitry further calculates a numerical value of at least one color for each pixel of the normalized spectral reflectance images of the measurement target, for respective ones of the plurality of illumination angles, to measure color of the surface of the measurement target.
