Abstract: A device for measuring flight data of a flying object by using a high speed image camera is provided. The device includes: a launch signal generator which determines whether the flying object is launched and generates a signal when it is determined that the flying object is launched; and a high speed image camera system which includes an integrated control unit and a high speed image camera which photographs the flying object after the launch signal generator generates the launch signal. The integrated control unit controls the high speed image camera and calculates preliminary flight data and final flight data from images photographed by the high speed image camera. A position through which the flying object passes at a point in time when a predetermined photographing time elapses is estimated using the preliminary flight data, and, on the basis of the position, an image capture area is set.
