There are 22 players competing for possession of the ball in the world’s most popular sport, football. We can learn a lot from watching football games, in addition to the experience they provide.
Here, I would like to contribute to the discussion of this subproblem of football analysis by showing how I was unable to interpret matches when evaluating their results using television-like video streams. Find out more at baanstepball.com.
You’re not satisfied with some aspect of your life
Moving cameras have a difficult time obtaining accurate positional and semantic information, despite being placed throughout the field. Due to their budgets and permission limitations, real stadiums cannot achieve this. With a tight budget, you can use video data in various ways while sitting in your chair.
Check out what you need to do
Instead of breaking up this massive task into more manageable, specific chunks like textbook programmers do, we chose to divide it into smaller pieces.
In response, we have established the following divisions:
- Players’ locations can be projected by means of a camera view in two-dimensional space.
- It is important to identify players, balls, and officials (such as their nationality).
- I need to track objects (also known as entities) for my project.
- A break between frames allows us to identify players, but is it possible? Is it possible to identify players?
- Being part of a team.
The next step will be an in-depth examination of a particular problem, such as positioning and semantics.
A field detection takes place during each frame sequence, as well as a field detection of entities (field detection). A field detection of an entity occurs whenever two or more events occur almost consecutively.
Each entity in the field is projected onto the camera in order to estimate its position relative to the camera. We can also track the performance of each player by identifying and placing them within a team.
The video should be repeated until the end has been reached if the video has ended. The video will smooth when it ends. In order to adjust the data, we ‘backward adjust’ the paths detected over the sequence by comparing their similarity.
Following the feed of a frame into the system, you can see what steps the system takes immediately.
Utilizing a method to detect objects
You will soon learn how hard it is to find good labeled data when you work with machine learning. Object locators like LoV3 are one of the most common methods to find objects.
The best choice is not to cut the frame or train the nets. To transmit the original resolution image, YOLO was used since accuracy is more important than speed. The referee or player can use this method if the ball is near them.
