摘要

PROBLEM TO BE SOLVED: To provide an attack pattern extraction apparatus that can extract more correct attack patterns considering the movement of all players participating in the sports game, and provide an attack pattern display device, an attack pattern extraction method, an attack pattern display method and a program.;SOLUTION: An attack pattern extraction apparatus includes units for: quantizing position information of each player in multiple attack opportunity, based on position history for representing the position information of each player in the multiple attack opportunity; generating a number vector for representing the number-of-times where a player moves between the quantized position information, in each of the multiple attack opportunity, using the quantized position information; generating a feature vector related to the movement and action of the player about each of the multiple attack opportunity, from the generated number vector and the play history for representing the action of each player in the multiple attack opportunity; and classifying the multiple attack opportunity into the multiple attack pattern, based on the feature vector about each of the generated multiple attack opportunity.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
