Method and system for the automatic detection of events in sport fields

SCHEDA BREVETTO

Abstract:

The present invention refers to the problem of the automatic detection of events in sport field, in particular Goal/NoGoal events by signalling to the mach management, which can autonomously take the final decision upon the event. The system is not invasive for the field structures, neither it requires to interrupt the game or to modify the rules thereof, but it only aims at detecting objectively the event occurrence and at providing support in the referees’ decisions by means of specific signalling of the detected events.

Advantages:

In order that such technique provides the best results, it is necessary giving particular attention to two main aspects: the phase of creating the background image and the phase of updating the image itself.
This procedure is always active when the system is in the status with jump=20, but is deactivated in all other cases in order to allow a better interpretation of the scene (for example the ball could be filtered by the procedure for analysing the connectivity when it is very near to a player or to a shadow thereof).
In order to obviate the problem, in this case the console verifies the motion linearity onto the 2D plane of the object detected by the active camera and in case of unreliability due to not linear trajectories, it continues to consider the data as reliable only if they result to be certified as ball examples both by the neural network based upon the pre-processing wavelet and by the one based upon the direct analysis of the grey levels.

Application field:

APPARATUS FOR PHYSICAL TRAINING, GYMNASTICS, SWIMMING, CLIMBING, OR FENCING; BALL GAMES; TRAINING EQUIPMENT;

ELECTRIC DIGITAL DATA PROCESSING;

RECOGNITION OF DATA; PRESENTATION OF DATA; RECORD CARRIERS; HANDLING RECORD CARRIERS;

COMPUTER SYSTEMS BASED ON SPECIFIC COMPUTATIONAL MODELS;

IMAGE DATA PROCESSING OR GENERATION, IN GENERAL

Technical board:

The present invention aims at solving the problem of the automatic detection of Goal/NoGoal events by signalling to the match management, which can autonomously take the final decision upon the event.
