Problems solved by technology

However, most of the existing technologies use the six-axis inertial sensor in the football to detect the overall acceleration variable and angular velocity variable of the football and establish an error model or equation to calculate the force on the center of mass of the football. However, its effectiveness is limited by the complexity of the corresponding relationship. Multivariate and Nonlinear Relationships

Embodiment Construction

[0032] The present invention will be further described below through specific embodiments.

[0033] A data processing method for a smart ball, which uses a six-axis inertial sensor 12 to detect three-axis acceleration variables, three-axis angular velocity variables, and rotational speeds of a ball. The six-axis inertial sensor 12 includes a three-axis angular velocity sensor and a three-axis angular velocity sensor. First, the sensor signal correction neural network is used to realize the preprocessing signal correction of the triaxial acceleration variable and the triaxial angular velocity variable, and then the centripetal force correction neural network is used to calculate the acceleration generated by the centripetal force. Finally, according to the acceleration generated by the centripetal force, the corrected triaxial acceleration and triaxial angular velocity, the actual triaxial angular velocity and triaxial angular velocity are calculated according to the following f...

Abstract

Provided are a smart ball, a system and a method. The smart ball system detects a three-axis acceleration variable and a three-axis angular velocity variable of a ball (10) by means of a six-axis inertial sensor (12). First, a sensor signal correction neural network is adopted to implement preprocessing signal correction on the three-axis acceleration variable and the three-axis angular velocity variable. Then, a centripetal force correction neural network is adopted to calculate the acceleration generated due to centripetal force. Finally, the actual three-axis acceleration and the actual three-axis angular velocity are calculated according to the acceleration generated due to centripetal force, the corrected three-axis acceleration and the corrected three-axis angular velocity. A new relationship of acceleration variable, angular velocity variable and centripetal force is provided by the smart ball, and a more accurate data basis is provided for the improvement of athletes' special ability.

Description

technical field [0001] The invention relates to the field of intelligent sports equipment, in particular to an intelligent ball, system and method. Background technique [0002] In recent years, the smart device industry has developed rapidly. One of the main reasons why smart devices are so sought after is the formation of an ecosystem for software application development and distribution for smart devices. Hundreds of new applications are coming to the market every day, constantly promoting the evolution of this ecosystem. However, in this huge number of software applications, pure software or web applications are the mainstream, and the use of various sensors (gravity sensors, gyroscopes, magnetometers, global positioning systems, etc.) inside smart devices is limited to maps and games. . [0003] In the prior art, smart devices are also used in sports, such as patent CN102779319A, which uses an intelligent monitoring system for outdoor sports, but this intelligent sys...
