Abstract

Different engineering structures like bridges, beams, concrete structures, etc are subjected to different problems due to the improper construction method adopted and carelessness during initial construction. They are also often subjected to fatigue stress, cyclic loading and other environmental changes, which creates breaks on the structures called cracks that results in the reduction of stiffness in the structure as well as creates deformities in the structure. Thus, it is necessary to detect and take preventive measures against cracks in order to prevent further damage and possible failures of the structures in order to avoid accidents and for easy maintenance and there requires the need of automated crack detection scheme. The proposed system consists of a robot, a high resolution camera to collect images of surfaces and a global map for locating the position of cracks. The robot will navigate on the surface of the structure like bridges to collect the surface image data at predetermined locations. An image processing technique is also used for processing the image.
