Volleyball track acquisition and intelligent analysis technology

Abstract

Volleyball has been developing rapidly since 1996. It has been widely used both in competitive events and among ordinary people. However, with the continuous improvement of the sports level, the traditional manual training methods cannot meet the existing technical requirements. It is a mainstream method to analyze the track of volleyball by the computer in volleyball training. However, there are still some technical problems such as low precision and incomplete analysis. Therefore, this paper puts forward the research of volleyball track acquisition and intelligent analysis technology. In this paper, the shortcomings of the existing technology are systematically analyzed, and on this basis, the optimization and improvement scheme is proposed. The core technology of this project is to improve the original image preprocessing technology and strengthen the system’s feature extraction ability. Finally, combined with the CAMSHAFT moving object tracking algorithm, the technical scheme of this paper is formed. Through a series of technical improvements, the system effectively improves the ability to extract and analyzing the track of volleyball. In order to further verify the practical effectiveness of this scheme, a number of comparative experiments including algorithm accuracy comparison experiment, trajectory recognition detection, and algorithm signal-to-noise ratio verification are carried out. The object of comparison is the current mainstream common filtering algorithm. Through the analysis of experimental data, this method is more accurate than the common filtering algorithm in the extraction of volleyball trajectory, which effectively improves the comprehensive performance and robustness of the traditional method.

Volleyball players’ mastery of sports skills and improvement of competitive level based on big data analysis

“…The degree of development of competitive sports has become an important symbol of the development level of material and spiritual civilization of countries and regions [1][2]. With the continuous promotion of China's education reform, volleyball teaching in China is gradually developing deeply and entering the golden era with the strong support of national policies [3][4]. Volleyball teaching, as one of the main elements in physical education, has a significant effect, and China is paying more and more attention to the future development of volleyball teaching [5][6].…”
