PROBLEM TO BE SOLVED: To provide a periodic motion observation system capable of accurately identifying a trajectory, a speed and a generation spot of distortion or the like on a periodic motion of an observation object i simple configuration.SOLUTION: A flash light is emitted for the unit of a predetermined period from a light source 1, a periodic motion at a predetermined observation point of an observation object M is imaged by an imaging camera 3, and an image relating to the periodic motion, that is imaged by the imaging camera 3, at the predetermined observation point of the observation object M is then analyzed by an image analysis device 4. On the basis of the image relating to the periodic motion at the predetermined observation point of the observation object M, the image analysis device 4 extracts coordinates of the observation point at the time when the predetermined observation point of the observation object is irradiated by the light source, and outputs the coordinates in a table format or a chart format.SELECTED DRAWING: Figure 2 |
