Abstract
The present invention provides an image processing apparatus for evaluating a surface of an object using a marker including marks whose positional relationship in a case where the marker is arranged in plane is known, the maker being arranged on the surface of the object. The image processing apparatus includes: a first acquisition unit configured to obtain image data obtained by capturing an image of the surface and an image of the marker arranged on the surface; a second acquisition unit configured to obtain information indicating positional relationship among the marks included in the marker; an extraction unit configured to extract the positional relationship among the marks included in the marker in an image indicated by the image data; and a correction unit configured to correct the image data based on the positional relationship indicated by the information and the extracted positional relationship.
