  • A visual programming language for soccer
    Publication . Belguinha, António; Rodrigues, Pedro; Cardoso, Pedro J. S.; Rodrigues, J. M. F.; Paciência, Domingos
    The use of Information Technologies (IT) in high competition sports is an instrument often used. However, the majority of the performers, including technical teams, do not have skills to program those IT tools to their needs. In this paper we present the low level implementation of a visual programming language (VPL) that allows the user without programming expertise to produce relatively complex programs by drawing them on a web application. The VPL tool application is illustrated by applying it to detect programmed situations from a soccer game, using previously obtained tracking data. The tool can be applied to other collective ball sports.
  • A computer vision based web application for tracking soccer players
    Publication . Rodrigues, J. M. F.; Cardoso, Pedro; Vilas, Tiago; Mendes Da Silva, Bruno; Rodrigues, Pedro; Belguinha, António; Gomes, Carlos
    Soccer is a sport where everyone that is involved with it make all the efforts aiming for excellence. Not only the players need to show their skills on the pitch but also the coach, and the remaining staff, need to have their own tools so that they can perform at higher levels. Footdata is a project to build a new web application product for soccer (football), which integrates two fundamental components of this sport's world: the social and the professional. While the former is an enhanced social platform for soccer professionals and fans, the later can be considered as a Soccer Resource Planning, featuring a system for acquisition and processing information to meet all the soccer management needs. In this paper we focus only in a specific module of the professional component. We will describe the section of the web application that allows to analyse movements and tactics of the players using images directly taken from the pitch or from videos, we will show that it is possible to draw players and ball movements in a web application and detect if those movements occur during a game. © 2014 Springer International Publishing.

  • Processing sports acquired information from a tracking system
    Publication . Rodrigues, J. M. F.; Belguinha, António; Cardoso, Pedro J. S.
    In order to improve the players’ and teams' performances in sports, the technical staffs are now using an ever increasing number of technologies. In this paper we present a study based on a video tracking of players and ball, that can return heat, passes and ball losses maps, which can be a good resource to measure a player/team performance and a base to their improvement.
  • Open source technologies involved in constructing a web-based football information system
    Publication . Rodrigues, Pedro; Belguinha, António; Gomes, Carlos; Cardoso, Pedro J. S.; Vilas, Tiago; Mestre, Renato; Rodrigues, J. M. F.
    The current information systems and match analysis software associated to professional football output a huge amount of statistics. Many football professionals are particularly interested in real time information about the tactical plan occurring during the match, and the relations between that information and what was prepared in the training sessions. It is fundamental to have on the bench, and on-the-fly, the most relevant information each time they have to take a decision. In this paper, we present a set of open source technologies involved in building a multi-platform web based integrated football information system, supported in three main modules: user interfaces, databases, and the tactical plan detection and classification. We show that the selected technologies are suitable for those modules, allowing field occurrences to trigger meaningful information.
