How do you calculate how far an athlete runs at the World Cup in South Africa?

The special technical and tactical video analysis system (SIMI°SCOUT) is used to measure the distance and running speed of football players under the conditions of the game, and obtain more objective and can reflect the actual situation of the athletes, such as the movement distance, running speed and range of motion, etc., to provide reliable data for coaches to scientifically formulate physical training plans and reasonably arrange the skills and tactics of the game.

The computer can record the running route of the players and then calculate it in proportion to the actual court.

Task Question Hope to be Thank you.

Someone is staring at it.

An estimated pitch is about 5,000 square meters.

According to FIFA statistics, the cumulative distance traveled by a professional footballer is currently 10,000 meters on average.

1. The average running distance of players in the five major European leagues is more than 12,000 meters.

2. The average running distance of players in the Chinese Super League is about 9,000 meters, and players who can run 11,000 meters in domestic competitions can be called immortal.

3. The record for the longest run in an international competition was set by David Beckham. In the 2001 World Cup qualifiers against Greece, he ran the kilometre. ‍

There are 32 teams with a total of x athletes, and the winner: x32=924

4x=32×92

x=736A: There are 736 athletes in 32 participating teams

All venues have electronic calculators installed on the sidelines to calculate the distance each player has run during the game, but it is usually more than the actual distance traveled and is only a reference data.

The software calculates his running distance in real time based on the video, which is very simple.

Non-visual inspection, in fact, the relevant computer technology is used to make a count of the 22 players on the field, such as how many passes, how many mistakes, how many shots, and how much distance they run. That's why there will be a more detailed technical statistics, this thing first emerged in UEFA, and the root cause is to imitate the NBA's judgment of the data, and learn from the Americans!

1) The force acting on the object is only instantaneous, and there is no strong effect on the object during the movement of the object, so it cannot be accurately calculated, so a and b are incorrect;

2) Although it is instantaneous, it also makes the object move, that is, work is done on the object, so d is wrong;

3) Calculate the work done by the athlete on the soccer ball according to w=fs, but this problem does not know the distance that the soccer ball moves in the direction of the force, so the conditions are insufficient to calculate

Therefore, C

In the data sampling competition, 8 advanced cameras with thermal imaging functions are installed in the stadium and used to record the whole process of the game. The information captured by the camera is broken down by a set of ultra-sophisticated analysis software, and the end result is what the customer sees, and the data is categorized in such detail.

The special technical and tactical video analysis system (SIMI°SCOUT) is used to measure the distance and running speed of football players under the conditions of the game, and obtain more objective and can reflect the actual situation of the athletes, such as the movement distance, running speed and range of motion, etc., to provide reliable data for coaches to scientifically formulate physical training plans and reasonably arrange the skills and tactics of the game.

A detailed introduction to the statistical method of player running distance!

It's not shoes. It's a camera, which can be measured with a positioning tracking system, and as for the shooting data, Football Weekly has introduced that it is a statistical company that uses manual touch screen statistics during live broadcasts.
