An inner crack measuring system on a real time basis is provided to measure crack progress rate automatically by taking a picture on the belt end of a tire on a real time basis. An inner crack measuring system on a real time basis comprises: a tire(3) making a second belt a surface on a thread of the tire to expose a third belt(1) and being vertically processed to the third belt; a camera(4) capturing an image in case the third belt passes when the processed tire is driving-tested in an inner driving tester; a synchronizer(5) synchronizing in order to capture the same location of the processed tire always when the camera captures the image; and a computer(6) in which the captured image is transmitted. The computer calculates the length of the crack according to the time by using the captured image.
