APPARATUS AND METHOD FOR MEASUREING A CRACK IN A CONCRETE SURFACE

摘要

Disclosed is a method for measuring a crack in a concrete surface, which comprises the following steps of: obtaining a color image of a concrete surface including a crack using a color camera; acquiring a depth image of the concrete surface using a depth camera; generating matching information by matching the color image and the depth image; correcting image distortion of the color image generated based on a shooting angle of the color image based on the matching information; and estimating crack information for the crack on the concrete surface based on the corrected color image.
