Personal goal video capture method and system

Abstract

The invention relates to a personal goal video capture method and system, and the method comprises the steps: obtaining the 3D positions of basketballs at all moments after the goal is identified, andobtaining a goal track according to the 3D positions of the basketballs at all moments, the basket position, the goal moment, and the motion state constraint; obtaining and determining the throwing time and throwing position of the current player based on the obtained goal track, determining the goal player according to the throwing time and throwing position based on the position of each playerat each moment, and outputting a goal video. Compared with the prior art, , the goal track is obtained through the 3D position of the basketball at each moment, the basket position, the goal moment and the motion state constraint, then the goal player is obtained based on the goal track, and the method can be achieved through simple and mature equipment such as a common monitoring camera and a common computer, so that it is achieved that the method is low in implementation cost, high in reliability and suitable for installation of a common court.

Description

technical field [0001] The invention relates to a computer technology, in particular to a method and system for capturing a personal goal video. Background technique [0002] With the development of the sports industry, computer science is increasingly used in the field of basketball, such as tracking players in real time, automatically counting and analyzing game data, predicting game results, and so on. Among these applications, identifying players, tracking player movements on the court, and recognizing player actions are some of the most important technologies. In recent years, with the development of hardware and software, these technologies have become more mature, faster and more accurate. [0003] In the current basketball game, there are mainly the following types of technologies that can capture the player's goal video and identify the identity of the shooting player: [0004] 1. In professional basketball games, multiple synchronous industrial-grade cameras are ...

AI Technical Summary

Problems solved by technology

The disadvantage is that the whole set of equipment is expensive, usually reaching hundreds of thousands of dollars, and the requirements for hardware equipment are relatively high. More importantly, it can only be used in regular games where players wear jerseys, and cannot be used in general public basketball.

[0005] 2. Use wearable devices, such as wrists, watches, and chip sensors on basketball equipment to identify the player's shooting action or obtain the ball's trajectory to identify goals based on the chip inside the ball. The disadvantage is that additional hardware equipment is required

The disadvantage is that it requires a lot of labor costs, and the follow-up statistical process is cumbersome, so it can only be used in more formal events

And it is difficult to obtain relatively high-level data such as shot position, running distance, and running range
