Abstract
A swing analysis device includes: an acquisition unit (swing video acquisition unit) acquiring a swing video of a user; a processing unit deciding an impact timing and a tempo, based on the swing video; and a display unit displaying the swing video and the tempo. The display unit, while displaying the swing video, displays the tempo when the impact timing is reached in the swing video.
Claims11
A swing analysis device comprising:
- a processor configured to
- acquire a swing video that is a captured image of a swing by a user,
- determine an impact timing and a tempo, based on the swing video,
- binarize a plurality of frames included in the swing video,
- compare a first frame of the plurality of frames with a second frame that is a frame immediately before the first frame,
- calculate a cumulative value of a number of pixels having different values, and
- decide the impact timing based on a change in the cumulative value over the plurality of frames;
- and
- a display configured to display the tempo when the swing by the user reaches the impact timing in the swing video.
