Method for processing an image of a concrete construction

A device for processing an image of a concrete construction that has been constructed by using a plurality of moldboards having vertexes arranged so that a vertex of the moldboard is located on a predetermined position relative to a contiguous moldboard, whereby the removed moldboards have left the prints thereof on the surface of concrete construction, the device comprising:

• a finder that determines positions of the print of vertexes of the moldboards in the image;
• and
• a modifier that corrects the image on the basis of the positions of the vertexes so as to remove distortion of the image.

A program for processing an image of a concrete construction that is constructed by using a plurality of moldboards arranged so that vertex of the moldboard is located on a predetermined position of relative to a contiguous moldboard, whereby the removed moldboards have left the prints thereof on the surface of the concrete construction, the program comprising the steps of:

• determining positions of the print of the vertexes of the moldboards in the image;
• and
• modifying the image on the basis of the positions of the print of vertexes so as to remove distortion of the image.

An image processing method for correcting distortion of a photographic image of a concrete construction having a curved surface in at least part thereof, that has been constructed by using a plurality of moldboards, characterized in that the photographic image is transformed so that the print of the moldboards on the curved surface are distorted as if they are printed by moldboards adjoining to each other in a plane.
