Abstract
This thesis explores the integration of artificial intelligence (AI) in the sports industry, focusing on the outcomes of a work carried out in collaboration with Deltatre, a prominent sports and entertainment company, to enhance the spectator experience and improve analysis tasks. The work investigates the use of mobile broadcast footage for the calibration of cameras in optical recognition systems. By utilizing accurate metric information from easily accessible videos, new opportunities arise for analysis, processing, and visualization of dynamic sports events. Camera calibration (CC) is utilized in various services in the sports industry, such as graphics, officiating, video assistant referee VAR), and goal-line technology (GLT).
However, the current approach relies on fixed cameras dedicated to each specific service and requires manual calibration on-site through a series of lengthy and complex operations
