Abstract

Potražnja za naprednom analizom sportskih susreta neprestano raste, a automatski sustavi za praćenje igrača postaju ključni alati za razumijevanje dinamike sportske utakmice. Ovaj diplomski rad bavi se razvojem sustava za automatsku detekciju i praćenje igrača na teniskom terenu, koristeći ulazne videozapise teniskih utakmica. Sustav kombinira detektor YOLOv8 za detekciju igrača, algoritam DeepSORT za praćenje igrača iz kadra u kadar te matricu homografije za preslikavanje pozicija igrača na... More dvodimenzionalni prikaz teniskog terena. U ovom radu temeljito je objašnjena teorijska podloga navedenih metoda, opisana je implementacija tih metoda u sustav te je predstavljen pseudokod implementacije svih komponenata. Također, prikazani su rezultati izvođenja sustava te su evaluirane preciznosti detektora i preslikavanja matricom homografije. Na kraju rada istaknuta su ograničenja implementacije te su predložena potencijalna unaprjeđenja. Less

Abstract (english)

The demand for advanced analysis of sports events is continually increasing, and automatic player tracking systems are becoming crucial tools for understanding the dynamics of a sports game. This thesis focuses on the development of a system for automatic detection and tracking of players on a tennis court, using video recordings of tennis matches as the input. The system combines the YOLOv8 detector for player detection, the DeepSORT algorithm for tracking players frame by frame, and a... More homography matrix for mapping player positions onto a two-dimensional representation of the tennis court. This work thoroughly explains the theoretical foundation of the aforementioned methods, describes their implementation in the system, and presents pseudocode for all implemented components. Furthermore, the system's execution results were displayed and the accuracy of the detector and homography matrix mapping were evaluated. Finally, the limitations of the implementation were discussed along with potential improvements. Less
