A system for measuring the position of the shackle line of badminton

Abstract

The present invention discloses a badminton binding line position measurement system. Sample materials are employed to manufacture m sample badmintons, m detection badmintons are beat by a sample badminton racket, and flight tracks A1, ..., Am of the m sample badmintons are recorded; the tracks and a standard track are subjected to track similarity comparison to obtain track similarity values B1,..., Bm of the m sample badmintons; the B1, ..., Bm are compared with a preset qualification similarity B to perform statistics of n track similarity values being larger than B in the B1, ..., Bm as test badmintons; the sample badminton racket beats the n test badmintons for k times to perform image collection of the n detection badmintons after k-times beat, and images C1, ..., Cn of the n detection badmintons after being beat are obtained; the C1, ..., Cn performs similarity comparison with preset comparison images D1, ..., Dn to obtain similarity values E1, ..., En of the n detection badmintons; and a detection badminton corresponding to the maximum value in the E1, ..., En is obtained as a qualified badminton.

Description

technical field [0001] The invention relates to the technical field of shuttlecock manufacturing, in particular to a system for measuring the position of a shuttlecock binding line. Background technique [0002] Badminton is a very popular sport. A badminton usually includes a ball seat, some feathers and some hoop lines. Each feather is composed of a rachis and a pinna. Each feather can be divided into a tail section connected to the pinna and a head section not connected to the pinna. The circumference is fixed on the ball seat, and the binding wire surrounds and connects each feather head section. 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 has influenced the promotion of badminton. ...
