Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Fig. 1 is a schematic flow chart of a training method for swinging a shuttlecock in a high-distance shuttlecock in an embodiment of the invention.
As shown in fig. 1, a badminton forehand high-distance ball swing motion recognition method includes:
acquiring a professional image of a professional athlete performing badminton high-distance ball swing action in a room with laser locators distributed all around by utilizing motion capture high-speed camera equipment, and extracting swing action track information of the professional athlete from the professional image to serve as swing standard action track information;
step two, acquiring a training image of the swinging motion of a practicer for badminton high and long distance by using motion capture high-speed camera equipment in a room with laser locators distributed all around, and extracting the swinging motion track information of the practicer from the training image;
step three, comparing the swing action track information of the practicer with swing standard action track information, and judging whether the swing action of the practicer is standard or not;
and fourthly, when the swing action judgment result of the practicer is not standard, playing back the swing action and the swing standard action of the practicer on the display screen, and identifying the position where the swing action of the practicer is not standard.
According to the invention, high-speed camera equipment for capturing motion actions is adopted in the first step and the second step, so that athletes wear special clothes which are beneficial to shooting and capturing by the high-speed camera equipment, and practice high-distance ball swing shooting in a room with laser locators distributed all around.
In the third step, the swing action track information of the practicer is compared with the swing standard action track information to obtain action similar information and action error information, and the result information of the swing action of the practicer is output after statistical analysis.
Further, in the first step and the second step, the swing action track information of the practicer and the swing standard action track information both include: preparing an action track, a racket leading action track, a batting action track and a racket following action track, and dividing the technical action into four steps according to the technical action characteristics of high-distance balls: preparing action, striking action, batting action and slapping action.
Further, in the third step, in the comparison between the swing action track information of the practicer and the swing standard action track information, if the difference between the swing action track information of the practicer and the swing standard action track information is within the range of a preset threshold, identifying and judging that the swing action track information of the practicer is standard; if the difference between the swing action track information of the practicer and the swing standard action track information is not within the range of a preset threshold value, identifying and judging that the swing action track information of the practicer is not standard; in this way, the technical movements of the professional players with normative movements are photographed and calculated in the above manner to become the standard of reference of the exerciser, and the exerciser compares the standard movements of the high-distance ball set in advance, and sets a certain range of difference data.
Further, in the second step, the motion of the exerciser is continuously shot by the motion capture high-speed camera device to form a group of photos, the computer performs matching recognition on the main body of the photos, and captures the exercise trajectory information of the exerciser in real time, wherein the main body mainly comprises the body parts of the exerciser, such as the arms, the shoulders and the like, and the trajectory route of the racket when the exerciser performs the high-distance ball swinging motion.
Further, in step four, will wave and shoot standard action orbit information and practitioner and wave and shoot action orbit information and set for two kinds of different colours, when practitioner waved the action orbit and has deviated from and waved standard action orbit, the display screen sends alarm signal, and like this, practitioner sets up standard exercise orbit and practitioner's exercise orbit as two kinds of different colours on the display screen in the room, has deviated standard orbit when practitioner's orbit, and equipment can send out the police dispatch newspaper voluntarily, can examine oneself action orbit after the exercise, and the action orbit image that the positive-handed high-distance ball that two sets of different colours waved will appear in the large screen, and practitioner observes own action and the orbit difference of standard action directly perceived in real time to according to the action suggestion, in time corrects the technical action.
