Abstract: Nowadays, crack detection has become an important necessity for the maintenance of bridge. Earlier, bridges were inspected by a method of human inspection, which had less accuracy in finding out the presence of cracks. So here a system is proposed that uses a robot equipped with a camera that captures images of crack. This images are evaluated using image processing techniques and finally cracks are been identified using edge detection procedures. Mainly canny algorithm is used for the purpose of detecting cracks. When a crack is detected messages are sent to the concerned authority with the help of GSM. This system thus works effectively as a safety system for bridge deck maintenance.
