[0020] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] As Figure 1The utility model provides a shuttlecock, the shuttlecock includes: base 10, wind resistance structure 20 is installed on base 10, and wind resistance structure 20 includes at least one shuttle feather 22, first light reflection structure, first light reflection structure includes at least two first light reflection piece 30, and at least two first light reflection piece 30 are arranged on the outer surface of base 10.

[0022] In the embodiment, by installing at least one shuttle feather 22 on the base 10, the air resistance of the shuttlecock during flight is increased, which helps to reduce the flight speed of the shuttlecock, prolong the rising and falling time of the shuttlecock, and prolong the residence time of the shuttlecock in the air. It can not only improve the operability, but also provide more opportunities for optical motion capture to capture the detailed motion of the shuttlecock. By arranging at least two first light reflection pieces 30 on the outer surface of the base 10, an additional light source is provided for the shuttlecock, so that the optical motion capture camera can more accurately track the motion of the shuttlecock, and realize the capture of the optical motion of the shuttlecock.

[0023] It should be noted that when the optical motion capture camera is working, it will emit light (usually infrared) to the shuttlecock, and the first light reflection piece 30 will reflect the light back to the camera. Since the reflection efficiency of the first light reflection piece 30 to the light is much higher than that of the surface of the base 10, the reflected light points captured by the optical motion capture camera will form bright points on the image. By analyzing the position changes of these points at different time points, the motion trajectory of the shuttlecock in space can be obtained.

[0024] In one embodiment, the shuttle feather 22 is a feather, which can be an animal feather or a man-made feather.

[0025] In one embodiment of the utility model, the first light reflection piece 30 includes a light reflection main body and a light reflection coating coated on the surface of the light reflection main body.

[0026] In the embodiment, the light reflection main body can be stably installed on the base 10, and the light reflection coating is coated on the surface of the light reflection main body. The light reflection coating has high reflectivity and low absorbance, so that the first light reflection piece 30 can serve as a light reflection marker, and the first light reflection piece 30 can reflect the light (such as infrared light) emitted by the optical motion capture camera, thereby obtaining the motion trajectory of the shuttlecock.

[0027] In one embodiment, the light reflection coating can be coated with light reflection paint or coated with metal silver.

[0028] In one embodiment of the utility model, the first light reflection piece 30 includes a light reflection main body and a light reflection adhesive tape wrapped around the outer periphery of the light reflection main body.

[0029] In the embodiment, the light reflection adhesive tape is wrapped around the outer periphery of the light reflection main body, so that the first light reflection piece 30 can form a reflection source.

[0030] It should be noted that the above-mentioned reflective tape is a reflective tape of the prior art, and the specific structure will not be described here.

[0031] In one embodiment, the first reflective part 30 comprises a reflective main body and an aluminum foil or a silver foil wrapped around the outer periphery of the reflective main body.

[0032] As shown in the drawings, in one embodiment of the utility model, the first reflective part 30 is spherical. Figure 1

[0033] In this embodiment, the first reflective part 30 is spherical, and the spherical first reflective part 30 has a large surface area, so that no matter from which direction the light is irradiated, the first reflective part 30 can reflect the light, thereby improving the reliability of tracking.
