Football motion trail real-time monitoring system

Abstract

The invention discloses a football motion trail real-time monitoring system. The system mainly comprises the following modules: a sensor module, a video acquisition module and a signal processing module. The sensor module comprises an accelerometer chip and a Bluetooth chip and is arranged in a football, and the video acquisition module comprises at least two camera positions. The working steps of the system are as follows: (1) calibrating a camera to obtain internal and external parameters of the camera; (2) using a triangulation method to position an initial ball opening position; (3) converting data of the acceleration sensor into a court coordinate system by using a coordinate conversion algorithm; (4) processing sensor data by using an integral algorithm, and calculating the current position of the football; (5) further processing the data by using a Kalman filtering algorithm to obtain more accurate football positioning; and (6) calibrating sensor data time and video signal time. The method is high in positioning precision, athletes do not need to wear equipment, and large-scale application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the field of information perception and computer technology, in particular to the technology of real-time monitoring of football trajectory. Background technique [0002] Football is a sport that is highly sought after by teenagers, and it is also recognized as the largest sport in the world. It can play a good role in strengthening the body; not only teenagers, but also people who enter social work have to bear huge burdens every day. work pressure, and if this pressure cannot be released well, it will further affect the mental state of the whole person, forming a vicious circle, and football can relieve this pressure very well. When people let go of all burdens, Playing a hearty game with golfers on the green field can greatly relax your mind and at the same time play a role in exercising your body; [0003] At present, in football training, various devices are often used to analyze the performance of athletes, and people pa...

Problems solved by technology

However, the information obtained by the current equipment is single, mostly focused on the user's running distance, heart rate and other information, and cannot obtain the user's actions on the football field; Positioning is combined to automatically identify the players serving, catching and shooting the ball, that is, to obtain action information such as serving, catching and shooting of each player (we can use the relative position of each player to the football and the trajectory of the football to determine judgment), so the present invention discloses a football track real-time monitoring system, the system calculates the position of the football in the field by using the football with a built-in accelerometer, with the help of video information and acceleration information, and improves the accuracy of football positioning. precision
