Problems solved by technology

The feathers used are usually the natural feathers of geese or ducks. The material of natural feathers is very light and rigid enough. The hitting feeling and flight trajectory are ideal when playing. scrapped
Therefore, the consumption of badminton is relatively large, and the cost of playing badminton is relatively high, which affects the promotion of badminton

Embodiment Construction

[0028] Reference figure 1 , The intelligent selection method of badminton restraint line position proposed by the present invention includes:

[0029] Step S1, making m sample shuttlecocks based on sample materials, and any two sample shuttlecocks in the m sample shuttlecocks have different binding line positions, wherein the sample materials at least include ball heads, feathers, glue, and binding lines;

[0030] In the process of making m sample shuttlecocks based on sample materials, the weights of the heads selected are the same, the weight, length, area, curvature, and bow of the feathers used are the same, the amount of glue used is the same, and the weight of the binding thread selected is the same.

[0031] In the specific scheme, in order to ensure the accuracy of subsequent detection, the weight of the ball head selected is the same, the weight, length, area, curvature, and bow of the feathers used are the same, the amount of glue used is the same, and the weight of the bin...

Abstract

The invention discloses a method for intelligently selecting the position of a badminton binding line, which includes: making m sample shuttlecocks based on sample materials; hitting m detection shuttlecocks with a preset force and angle with a sample racket, and recording m flight trajectories R 1 …R m ; put R 1 …R m Compared with the standard trajectory, m trajectory similarity values ​​T are obtained 1 …T m ; put T 1 …T m Compared with the qualified similarity T, the statistics T 1 …T m The sample shuttlecocks corresponding to the n trajectory similarity values ​​greater than T are used as test shuttlecocks; image acquisition is performed on n test shuttlecocks to obtain n comparison images H 1 …H n ; Use the sample racket to hit n test shuttlecocks k times with preset strength and angle; perform image collection on n test shuttlecocks after k hits, and obtain n images F after being hit 1 …F n ; put F 1 …F n with H 1 …H n Compare to get n similarity values ​​Q 1 …Q n ; Get Q 1 …Q n The detected shuttlecock corresponding to the medium maximum value is a qualified shuttlecock.

Description

Technical field [0001] The invention relates to the technical field of badminton production, in particular to a method for intelligently selecting the position of the badminton binding line. Background technique [0002] Badminton is a very popular sport. Badminton usually includes a tee, a number of feathers and a number of hoops. Each feather is composed of a shaft and pinnacles. Each feather can be divided into a tail section connecting the vanes and a head section without the feathers. The circumference is fixed on the ball seat, and the binding line surrounds and connects the feather head sections. The feathers used are usually the natural feathers of goose or duck. The material of natural feathers is very light and rigid enough. The hitting feeling and flight trajectory when playing a ball are ideal. However, due to the great force when playing the ball, the feathers are easy to break, resulting in the whole ball. scrapped. Therefore, the consumption of badminton is rela...
