A device and method of detecting a concrete crack is able to detect a crack on an external appearance of a concrete structure in a remote distance using an unmanned aerial vehicle and a digital image processing technique even in a position where it is difficult to acquire an image of the crack of the concrete structure. To achieve this, the present invention comprises: an aircraft body, a plurality of quad-rotor portions, an ultrasonic distance sensor, an image processor, and a controller.
