Then the cracks are photographed in a narrow field view at the predetermined spacing along the cracks based on the rough position information by a light section method. The narrow field images are processed to obtain the position, width, and depth of the crack at each predetermined spacing, which compose crack data at the series of points, and the cracks are repaired based on the crack data at the series of points.
