specific Embodiment approach

[0062] As a specific implementation of the method for calculating and indicating the thickness and thickness of the cut ball provided by the present invention, step D includes:

[0063] According to the formula F=arcsin(D 1 / D) Calculate the angle F between the first collision line and the axis of the club, where D 1 is the distance between the center of the target ball in the image and the center of the virtual ball, and D is the diameter of the target ball measured in the image;

[0064] Calculate the distance between the center of the target ball and the imaging component according to the formula L=kD to determine the position of the first collision line, where k is the conversion factor between the image length and the actual length, through the scale ratio in the image, the prior According to experiments or calculations, D is the diameter of the target ball measured in the image; or, the position of the center of the target ball is directly measured and converted by the ...

Embodiment approach

[0098] Please also refer to Figure 1 to Figure 3 , as a specific embodiment of the billiards posture adjustment device provided by the present invention, the position where the shoulder connecting assembly 30 and the arm connecting assembly 40 are rotatably connected is also provided for detecting the gap between the shoulder connecting assembly 30 and the arm connecting assembly 40. The three-dimensional angular ruler of the three-dimensional rotation angle of .

[0099] The three-dimensional angle ruler includes a first angle measurement module coaxially connected with the shoulder front connection assembly 30 and a second angle measurement module coaxially connected with the arm connection assembly 40, and the first angle measurement module is vertically connected with the second angle measurement module or It is arranged integrally, and the three-dimensional rotation angle between the shoulder front connection assembly 30 and the arm connection assembly 40 is obtained thr...

Abstract

The invention provides a cutting ball thickness aiming calculation instruction method, a mechanism and a billiards posture adjustment device, which belong to the technical field of billiards practice auxiliary equipment. The method includes the following steps: using an imaging component in the same direction as the club to obtain an image of the target ball; image processing, measuring the diameter of the target ball in the image, and calculating the position of the center of the target ball to obtain the center of the virtual ball; Calculate and obtain the first collision line formed by connecting the center of the virtual ball and the center of the target ball. The mechanism includes a connecting body, a connecting rod, an imaging component, a data processing module and a display module. The billiards posture adjustment device includes the above-mentioned cutting ball thickness aiming calculation indicating mechanism, a cue stick fixer, a front shoulder connection assembly, an arm connection assembly and a rod holder. The invention can be moved and used conveniently as a whole, can improve the perception efficiency of the user, is beneficial to reduce the difficulty of controlling the thickness of the chip, is beneficial to improving the practice efficiency, shortens the practice time, and is beneficial to the rapid improvement of the level.

Description

technical field [0001] The invention belongs to the technical field of billiard practice auxiliary equipment, and more specifically relates to a calculation and instruction method for cutting ball thickness and aiming, a mechanism and a billiard posture adjustment device. Background technique [0002] At present, in billiards, the success rate of golfers is very low when hitting long-distance or large-angle target balls, because there is no reference for players to refer to the thickness of the ball or the goal point aimed at, while newcomers are practicing billiards Generally, through the guidance of the coach, it takes a long time to observe and accumulate experience to grasp the traveling route of the target ball after hitting the ball. Only when the traveling route of the billiard ball can be roughly estimated can the thickness of the chipped ball be determined. Understand, so as to play a better shot, but this process is relatively slow and relatively difficult, which l...
