要約
(EN)

A measurement apparatus includes an illumination device irradiating an object with a first and a second pattern, a camera taking image data of the object, a motor displacing the object, and a processor measuring the object, obtaining a first value of the object based on a first number of image data taken with the first pattern at a first number of phases at a first position, obtaining a gain and/or offset based on the first number of image data, obtaining a second value of the object based on the gain and/or offset and a second number of image data taken with the second pattern at a second number of phases at a second position, obtaining height data of the object based on the first and the second value, and obtaining the second value with an average of the gain and/or offset of pixels adjacent to each pixel.
