Abstract: This ball game video analysis device: receives movie frames captured by cameras; computes the trajectory of the three-dimensional positions of a ball using the received multiple movie frames; determines, on the basis of a change in the ball trajectory, whether or not any action has been made by a player with respect to the ball; in the case when there has been such an action, selects, as an action frame, the movie frame corresponding to the timing at which said action was made; and identifies, from the action frame, a player who made that action.

Abstract: The present disclosure provides a person tracking method of tracking a person with high precision. According to a person tracking method and a person tracking device of the present disclosure, a processor determines coordinates of a plurality of persons of a video within the video. The processor specifies a group area as an area where the persons of the video are dense. The processor tracks coordinates of a certain person within the video. The processor determines a locus of coordinates of the certain person in the group area based on coordinates of the certain person out of the group area and a number depicted on a clothing.

Abstract: A person's behavior monitoring device includes a processor for acquiring a captured image of each of a plurality of cameras, acquiring information relating to a person requiring special attention by analyzing the captured image, and generating a monitoring image including the information, in which the processor determines, for each of the cameras, whether or not a person detected from the captured image is a long-time stayer who stays for a long-time in a capturing area of one of the cameras based on a result of tracking the person, and superimposes and displays a person rectangle that enables identification of a degree of stay on the captured image in correspondence with a person corresponding to the long-time stayer.
