| In this new era of rapid change and development,artificial intelligence,the Internet of Things,cloud computing,etc,have been widely used in social development.Related scientific research in the field of sports is also developing rapidly,and the use of big data,through computer software for the technical and tactical statistical analysis of game video,has been widely used in the field of sports.Table tennis as a skill-led barrier project,technical and tactical is the core factor of the sport's success.With the development of table tennis,table tennis all kinds of technical and tactical innovation and play style,athletes from all countries have themselves style of competition,so only a variety of technical and tactical play of scientific statistical analysis,to find out the way to win the enemy.At present,more researchers for table tennis technique and tactics analysis,still use the method of paper and pen statistics,how to improve the efficiency and effect of table tennis technical and tactical statistical analysis is a major issue facing many researchers.This study will use advanced sports code software to build a video statistics system suitable for the technical and tactical characteristics of table tennis,so that it has convenient operation,can make most researchers as soon as possible to become proficient in the use,for the follow-up researchers to provide new statistical methods and statistical ideas.China is a strong table tennis country,in recent years,the competitive results have been the leading,the technical and tactical use of national table tennis players is the main research object of foreign sports teams.In today's high-tech development,each national team is through big data analysis of the opponent's technical and tactical characteristics,and then develop targeted training and tactical play.In Japan,the statistical analysis is most obvious,the 18-year-old Ito Meicheng in June 2018 in the Japanese Open women's singles final,china's Wang Manyu,and the same year the Swedish Open women's singles champion won the title,resulting in the three main players of the national table tennis women's team Liu Shiwen,Ding Ning and Zhu Yuling have encountered Waterloo,The battle of the champion is the world's No.1 Zhu Yuling,played completely dumb,had a side-by-side situation in the game,shocked the world table tennis arena,Ito Meicheng's tactical approach is entirely for the individual athletes of the private custom.This study will use Sports Code technical andtactical analysis software to build a technical and tactical video statistical analysis system suitable for the characteristics of table tennis projects,to improve the effectiveness of table tennis training in China to provide new ideas,the Chinese women's team's main rival Ito Meicheng's major game video materials research and set up a video database,Through comparative analysis,we provide the competition suggestions for Ito Meicheng for women's ping-pong in China,and provide data reference and theoretical support for the coaches to innovate training methods and improve the training effect.Based on the characteristics of ping-pong projects,this paper designs a video statistical analysis system of ping-pong techniques and tactics based on sports code software based on the methods of the questionnaire,three-paragraph evaluation and data analysis.By using this system to take the main opponent of the Chinese women's team,Ito Meicheng,as an example,with its 39 games for application verification,through the data matrix analysis of her technical and tactical characteristics.After coding statistics,the game video block is correlated according to the name of the corresponding statistical indicator and builds the database,which improves the effective application value of the video data and provides a new way of thinking for the table tennis video statistics.The conclusions of this study are as follows:(1)For the first time,the video technology and tactics statistical concepts and methods of sports code software will be integrated with the table tennis project,the ping-pong ball technical and tactical video information and digital information combined,for the future teams according to their own needs to establish a table tennis technical and tactical statistical system to provide ideas for more researchers to provide table tennis techniques and tactics research means.(2)The use of sports code technical and tactical video analysis software,can be a specific object of the game or training video collection,technical and tactical analysis,video playback,software "matrix" function,can be intuitively and quickly to obtain the data for the event analysis,which not only improvethes the efficiency of the staff,You can also use data to develop targeted plans.(3)Combined with sports code software to establish a video database model of table tennis games,it is very convenient to analyze the video data in accordance with the relevantindicators stored,improve the application value of video data,for other researchers to collect,organize and consult important game video data provides a theoretical basis.(4)Ito Meicheng's playing style is in the midst of change to actively look for attacking opportunities.Ito Meicheng is good at fighting with two anti-glue players and chippers,technical and tactical approach mature.In contrast,with the backhand particle player against the match phase of the attack rate decreased,backhand glue can not fully play the effect. |
