NBA first introduced the body sense tracking technology, sports big data is really coming

According to Science and technology blog http://www.aliyun.com/zixun/aggregation/6139.html ">mashable.com reported that the U.S. NBA and Stats LLC company announced a few days ago, The 2013-2014 season will be fitted with a body-sensing tracking technique in all stadiums.


, what's going on with this cooperation?


Stats's SPORTVU player tracking system includes 6 cameras and specialized software. The system will be installed in 30 NBA teams, recording and tracking basketball and player movements. The system will provide continuous data flow and innovative statistical data, including speed, distance, player spacing, and ball control, to achieve more targeted analysis.


In addition to NBA TV, NBA.com website and NBA Game time application will also provide data from SPORTVU. "We are a data-driven alliance, and our expanded collaboration with stats will give the team and fans more ground-breaking data," said Steve Helms, executive vice president of NBA operations and technology. In this new era of statistical information, SPORTVU is a priceless resource for the basketball industry and enthusiastic fans. ”


Stats CEO Gari Vollas said: "The new NBA terminology will include speed files, offensive tactical types, defensive alignment and field coverage map." ”


Some people may still think that the NBA is just a player's personal performance, but this movement tracking technique may give them a different perspective. If LeBron James's every attack in the 7th game last year was made into GIF animation, the system would be worth it.


NBA has long been the expert in data statistics


according to related reports, since the 1980 's, the NBA began to use data management technology, all players scoring, rebounds, assists, caps, steals, errors, fouls and other fields of data are counted in the column. The NBA detailed and meticulous data statistics, not only can provide a single player query work, can also compare two players, including two pairs of attack and defense performance, such as James Field can get 28 points, Kobe Bryant for 27 points, but when two people meet, Kobe Bryant field can get 30 points, James only 24 points.


NBA data statistics and management has been accumulated and improved over the past 30 years. This is the NBA and the team's valuable wealth.


How does it serve the team?


For example: Statistics can be found, James in the basket on the left dribble, the choice of shooting, and when he is located on the right side of the basket, the main attack is to break the layup. This statistic tells the defender that when James is on the left side of the basket, you can choose a tight-fitting to block him, blocking his shot, because he will not break from the left, and when James came to the right side of the basket, he can not press, so easy to be a step over his left behind, when the good defender will choose to stay away from James two steps, Because he will not choose a jumper, no need to leave a cover of choice, empty enough distance, but can prevent him from breakthrough.


almost every player has relevant data to decipher its strengths and limitations. In the NBA, for example, the number of times Yao has missed the ball in the basket is more than the conclusion that Yao is usually able to dribble three times with his right hand and dribble two times on his left hand. This statistic tells the defender that if he wants to lift Yao's threat to the basket, he must be confined to the area away from the rim, so he has to dribble more than three times before he can get to the basket, so he often misses.


reports that 15 of the 30 NBA teams have hired at least one team of data analysts, who typically make important recommendations on the day of the contest, the draft meeting and the deal decision. Moreover, the top teams in the league are their own data analysts, including the top six division teams, and the magic and calf are employed by full-time data analysts and permanent teams. The impact of the data analysis on the team's record has also been reflected. Of the 15 teams who spent their energy on data analysis, their average winning rate reached 59.3%, while the team with no analytical work had a 40.7% average.


presumably, in the future, there is a sense of tracking help, the NBA team of data analysts, but also the analysis of the assistant and basis. And the physical sense of tracking into the arena, will further deepen the sports large data process.
