INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, INFORMATION PROCESSING DEVICE PROGRAM, AND RECORDING MEDIUM

摘要

An information processing method includes: acquiring setting pseudo multipole information on a pseudo multipole (S10), the setting pseudo multipole information being set such that color information on poles p1 and p2 is related to color information on an object 2, the poles corresponding to a plurality of points in an image of a single predetermined frame 20; specifying a position of the pseudo multipole in an initial frame and seeking an image of a single frame in the video for the pseudo multipole (S14), the pseudo multipole having poles whose colors conform to colors in the color information on the poles in the acquired setting pseudo multipole information, a distance between the poles of the pseudo multipole being equal to or less than a predetermined distance; specifying a position of the found pseudo multipole in the image of the single frame of the video (S17); and tracking the object on the basis of the position of the pseudo multipole found from the image of the single frame and the position of the pseudo multipole found from an image of a frame preceding the single frame in a reproduction direction of the video (S18).

主权项

1. An information processing device that tracks a predetermined object in a video having a plurality of frames, comprising:
at least one memory configured to store computer program code; at least one processor configured to access said computer program code and operate as instructed by said computer program code, said computer program code including: setting pseudo multipole information acquisition code configured to cause at least one of said at least one processor to acquire setting pseudo multipole information on a pseudo multipole, the setting pseudo multipole information being set such that color information on poles is related to color information on the object, the poles corresponding to a plurality of points in an image of a single predetermined frame; setting distance information acquisition code configured to cause at least one of said at least one processor to acquire setting distance information in which distances between the poles of the pseudo multipole are set in a discrete manner; initial position specifying code configured to cause at least one of said at least one processor to specify a position of the pseudo multipole in an initial frame; seeking code configured to cause at least one of said at least one processor to seek an image of a single frame in the video for the pseudo multipole, the pseudo multipole having poles whose colors conform to colors in the color information on the poles in the acquired setting pseudo multipole information, a distance between the poles of the pseudo multipole being equal to one of the distances in the acquired setting distance information; position specifying code configured to cause at least one of said at least one processor to specify a position of the found pseudo multipole in the image of the single frame of the video; and object tracking code configured to cause at least one of said at least one processor to track the object on the basis of the position of the pseudo multipole in the image of the single frame specified and the position of the pseudo multipole in an image of a frame preceding the single frame in a reproduction direction of the video which at least one of the at least one process has specified via the initial position specifying code or the position specifying code.
