In Data Volley software, several types of data are available to be recorded and presented by some basic code. 1 shows) is simple and clear, so that the game data can be quickly input through the keyboard and mouse operations.

The software interface of Data Volley (as Fig. Thus, the requirement of expected automatic data acquisition method can be decided. In order to achieve the development of the automatic Data Volley system, the data categories and functions utilized in Data Volley should be made clear. Therefore, this article targets on the automatic and precise game data acquisition method to development the automatic Data Volley system with high reliability and efficiency of the volleyball game analysis. This input process not only costs large human labor and time but also lacks of data accuracy since human eyes are weak at measuring the distance, velocity and time. In Data Volley, all input data are observed and judged by peoples through watching the game. This software can not only record the technical and tactical playing data of the players from both teams by a convenient interface, but also get a variety of statistical analysis data immediately in the statistical process, which helps the coaches to conduct real-time analysis and on-the-spot guidance for the game.

Once the volleyball game data can be acquired by computer vision method, other game data can also be obtained in similar way.įor the data acquisition and analysis of volleyball game, Data Volley is the most widely used software for professional statistics analysis of volleyball games. From this point of view, volleyball is a typical object of 3D sports analysis, since both the ball and the players require the 3D concept to describe their motions. However, most existing practical products for data acquisition only extract and present the game data (such as the position information) in the image coordinate system.

However, the social network for utilizing big data is mature while how to obtain the data becomes key problem in real applications.įor the data acquisition in real game, only the 3D physical data (especially the position and speed information) make sense in data analysis and strategy development. Some researches pay attentions to the applications of sports analysis based on big data, which will undergo major changes thanks to the utilization of the big data. Therefore, the big data of the network are expected to support the sports analysis and other applications. The performance of the sports analytic tools and the reliability of the game strategy development are depending on the quality and quantity of the game data. In the strategy development and coaching system, abundant game data help the teams and players to know their strengths and weaknesses, so that the proper strategy and personal training plans can be developed efficiently. In game broadcasting, precise and real-time game data will provide much more attractive contents to the audiences to understand the game status.

With the high-speed development of the vision sensing devices, the vision-based sports analysis technologies contribute in more and more fields, such as TV broadcasting contents, strategy development and coaching system. The results show 94.1% rounds are successfully initialized, the event type detection result achieves the average accuracy of 98.72%, and the success rate of the events’ quality evaluation achieves 97.27% on average. Experiments are conducted on game videos from the Semifinal and Final Game of 2014 Japan Inter High School Games of Mens Volleyball in Tokyo Metropolitan Gymnasium. At last, to estimate the quality, the relative spatial filters are proposed by extracting and describing additional features of the subsequent condition in different situations. Second, the team formation mapping with sequential motion feature is proposed to deal with the detection of event type, which represents the players’ distribution from the spatial concept and the temporal relationship. By using the temporal continuity of image features, the variance of team state distribution can be approximated so that the initial state of each player can be filtered out. First, the time-vary fission filter is proposed to generate the prior state distribution for tracker initialization.
This paper combines temporal and spatial features of the game information to achieve the game data acquisition. To develop the automatic data volley system, the vision-based game data acquisition is a key technology, which includes the 3D multiple objects tracking, event detection and quality evaluation.
Data Volley is one of the most widely used sports analysis software for professional volleyball statistics analysis.
