We aim to develop the method that automatically detects the cracks from the images that were taken from the concrete inner surface in tunnels, etc. Assuming that the images are taken from the mobile mapping systems, we have considered the method utilizing the crack's projection model on the projection plane of moving cameras. By the prototype, we tried to process the 2mm/pixel images in order to detect the 0.3mm-wide cracks, which have registered as the real crack by the human inspectors. As the result, most of the cracks were detected.
