PROBLEM TO BE SOLVED: To measure behavior of a mobile object without using a special instrument.SOLUTION: A behavior measuring device 10 measures behavior of a mobile object on the basis of: a first image that shows a state where a golf ball 20 is placed at a movement start point P0; and a second image that is an image after the golf ball 20 is hit and starts moving. A moving direction is calculated from a displacement direction of the mobile object between positions in the two images. And, a rotational axis direction is calculated from a difference in position and direction of a pattern of the golf ball 20 between the two images.SELECTED DRAWING: Figure 1 |
