Embodiment Construction

[0052] The preferred embodiments of the present invention will be described in detail below.

[0053] The present invention relies on figure 1 The shown intelligent fighting training system includes a fixer (1), an elastic rope (2), and a fighting ball (3), and also includes an inertial navigation sensor (31) that detects the acceleration and direction of the fighting ball. A program for computing data and a server for running the program.

[0054] An acceleration-based intelligent fighting ball training ball recognition method according to Embodiment 1 of the present invention, the flow chart of the method is as follows figure 2 shown, including the following steps:

[0055] Step S01, acquiring the acceleration value detected by the inertial navigation sensor;

[0056] Step S02, decomposing the acceleration value into tangential acceleration and centripetal acceleration according to the tangential and centripetal directions of the swing of the fighting ball;

[0057] Ste...

Abstract

The invention discloses an acceleration-based intelligent fighting ball training ball recognition method and system. The method comprises the steps of: obtaining the acceleration value detected by the inertial navigation sensor; decomposing the acceleration value into tangential acceleration and centripetal acceleration; calculating the instantaneous variation of the tangential acceleration of the fighting ball; judging whether the instantaneous variation of the tangential acceleration is greater than the instantaneous acceleration threshold, If so, it is determined that the fighting ball is effectively hit; the value of the number of times i of the fighting ball being effectively hit at the current moment is obtained, and if i is greater than 1, it is determined that the ball has been kicked off at this time; The centripetal acceleration data of the fighting ball constitutes a set; the number of centripetal acceleration data with a value of 0 in the set is counted; if the number is less than 2, it is determined that this is an effective ball for fighting training. The method and system of the invention solve the technical problem of how to identify whether the boxing trainer based on the inertial navigation sensor can effectively catch the ball during boxing training.

Description

technical field [0001] The invention belongs to the field of intelligent fighting training, in particular to an acceleration-based intelligent fighting ball training ball recognition method and system. Background technique [0002] Authorized notification number CN 204972956 U is a utility model named "a fighting functional training device", which includes a fixer, an elastic rope (elastic rope) and a hitting object (fighting ball), and the fighting training device is used for personal fighting training . [0003] The existing combat training devices based on inertial navigation sensors cannot automatically and accurately identify whether the combat training is effective in catching the ball, so that statistical analysis of the effective hitting data during combat training cannot be performed. [0004] At present, there is no technical scheme for automatically identifying whether the boxing trainer based on the inertial navigation sensor is effectively catching the ball dur...
