What is the function of the Tracker
The Sport Tracker is currently designed to automatically track motion in a Basketball event.
In this type of sporting event, all players follow the ball, and therefore, the Tracker can exclude the area which is without movement. The Sport Tracker switches between the connected cameras and their view areas or PTZ positions, to one outgoing stream based on the movement in the video feed from the camera.
How to set up the analytical and tracking zones
Firstly, you have to create an analytical zone that is used strictly for deciding which camera will be played. Try to exclude all disruptive elements like the audience in the auditorium or a coach entering the playground. Also, consider that the view area should be without any graphics (create a view area just for analytics). An example of what the settings could look like is below.
In most cases, you will need left and right tracking zones. Draw two rectangles above the analytical area you wish to allocate as zones. The Tracking zones should not overlap each other. Movement within the intersection of the analytical and tracking zones are considered for switching between added cameras.
How the switching to particular zones is performed
In the case of when you have two tracking zones it works as follows:
- Movement is in both tracking zones – overview camera is used for broadcasting
- Movement is only in one tracking zone – camera assigned to that particular tracking zone with movement is used for broadcasting
Consider that the outer full line of the border is used when somebody leaves the zone and the dashed line is used for incoming players. It prevents image skipping when someone stands on the border.
How the Sport Tracker can be configured
The Sport Tracker in the CamSwitcher App can be used in the following combinations. Nevertheless, the CamSwitcher App has to be always installed on the camera which provides the video data for analytics.
Example of one-camera installation: you can use a 4K camera e.g. P1378 and broadcast in FullHD. For the left and right cameras create two additional view areas each with FullHD resolution and place them in the corresponding positions in your image. The overview/analytic camera uses the entire picture from the camera in FullHD and the left and right zones will use the created view areas.
Example of multiple cameras installation - install one camera above the playground with CamSwitcher App and use it for the video analytics in the Tracker (when the camera is above the playground, you can eliminate disruptions). As an overview camera, use a camera placed beside the playground and for the left and right zones, use view areas from the same camera or separate cameras placed on their best positions, to enable capturing the left and right sides of the basketball court.
