Image recognition system and image recognition program
First Claim
1. An image recognition system that recognizes motions of players of a sport playing between areas partitioned by an obstacle such as a net from a content of its on-air program, of its material video before broadcasted, or recorded by a recording media such as a VTR, and characterized by comprisinga visual information obtaining device that obtains visual information on which a motion of the player in at least one area during a match is shown from the content,an occlusion state determining device that determines whether or not a used material such as a ball that moves between the areas included in the visual information obtained by the visual information obtaining device and that is an object to count the score of the relevant sport is in a state being hidden by a predetermined object body,an impact time information specifying device that specifies an impact time when the used material is hit based on an occlusion start time when the occlusion state determining device determines that the used material changes its state from not being hidden by the object body to being hidden by the object and an occlusion release time when the occlusion state determining device determines that the used material changes its state from being hidden by the object body to not being hidden by the object,a rule information storing device that stores rule information to conduct the relevant sport, andan image content recognizing device that recognizes an image content including the motion of the player shown by the visual information based on the visual information obtained by the visual information obtaining device, a position of the used material at the impact time specified by the impact time information specifying device and the rule information stored in the rule information storing device.

Abstract
An image recognizing device for recognizing the motion of a player on the basis of a content containing a sport in which players play in zones demarcated with an obstacle such as a net, including a video information acquiring section for acquiring video information representing the motion of the player in play from the content, a hidden state judging unit for judging whether or not a use tool such as a ball moving between the zones and being an object of scoring is in a hidden state by a predetermined object, a hit time information determining section for determining the time at which the use tool hits on the basis of the hiding start time at which the use tool is judged to be hidden by the hidden state judging section and the hiding stop time at which the hiding is judged to be stopped, a rule information storage section in which rule information on the sport is stored, and an image content recognizing section for recognizing the image content including the motion of the player represented by the video information on the basis of the video information acquired by the video information acquiring section, the position of the use tool at the hit time determined by the hit time information determining section, and the rule information stored in the rule information storage section.

19. An image recognition program stored in a computer readable medium that is a program activating an image recognition system that recognizes motions of players of a sport playing between areas partitioned by an obstacle such as a net from a content of its on-air program, of its material video before broadcasted, or recorded by a recording media such as a VTR by operating a computer, and characterized by making the computer function as
a visual information obtaining means that obtains visual information on which a motion of the player in at least one area during a match is shown from the content, an occlusion state determining means that determines whether or not a used material such as a ball that moves between the areas included in the visual information obtained by the visual information obtaining means and that is an object to count the score of the relevant sport is in a state being hidden by a predetermined object body, an impact time information specifying means that specifies an impact time when the used material is hit based on an occlusion start time when the occlusion state determining means determines that the used material changes its state from not being hidden by the object body to being hidden by the object and an occlusion release time when the occlusion state determining means determines that the used material changes its state from being hidden by the object body to not being hidden by the object, a rule information storing means that stores rule information to conduct the relevant sport, and an image content recognizing means that recognizes an image content including the motion of the player shown by the visual information based on the visual information obtained by the visual information obtaining means, a position of the used material at the impact time specified by the impact time information specifying means and the rule information stored in the rule information storing means.
