Patent attributes
An information processing device includes: a captured image acquiring section that acquires data of an image captured of a target space including a light-emitting marker emitting light in a predetermined color; a score map preparing section that determines, for each of pixels making up the captured image, a score value indicative of the certainty of how likely a target object represented by an image including the pixel is emitting light in the predetermined color on the basis of a pixel value, the score map preparing section further preparing a score map associating the score values with an array of pixels on an image plane; a target region extracting section that extracts from the score map an aggregate of pixels meeting predetermined criteria as a region constituting an image of the light-emitting marker; and a position information generating section that, on the basis of the position of the extracted region, generates and outputs position information about the light-emitting marker in a real space.
