    Abstract: An information processing apparatus includes a captured image acquisition unit configured to acquire an image captured by imaging a device that includes a plurality of markers, and an estimation processing unit configured to estimate position information and posture information of the device on the basis of a marker image coordinate in the captured image. The estimation processing unit includes an extraction unit configured to extract N marker image coordinates in the captured image, N being an integer equal to or greater than three, and a position and posture derivation unit configured to derive the position information and the posture information of the device from the extracted N marker image coordinates and three-dimensional coordinates of N markers in a three-dimensional model of the device. The extraction unit extracts, where selected N+A marker image coordinates have a predetermined positional relation, N marker image coordinates from among the N+A marker image coordinates, A being an integer equal to or greater than one.

    Abstract: An information processing device disposes an object model of a target object in a virtual space, and projects a polygon of a marker onto an imaging plane. Visibility indicating a degree of occlusion of the marker is calculated from an area of an image of the marker on a model thereby obtained and an area of a corresponding image of the marker in a photographed image. When the visibility is equal to or higher than a threshold value, positional information of the marker which positional information is derived from the photographed image is determined to be valid, and is output to be used in calculation of position coordinates of the target object after a weight coefficient is determined. When the visibility is lower than the threshold value, the positional information of the marker is determined to be invalid, and is not output.

    Abstract: Two light-emitting units are to be prevented from overlapping each other in an image obtained through a camera. A tracked unit (30) has a first outer surface (A1) provided with a first light-emitting unit (H1), a second outer surface (A2) provided with a second light-emitting unit (H2), and a light shield portion (B). The second outer surface (A2) faces a second direction different from that of the first outer surface (A1). The light shield portion (B) is located further outside than the first light-emitting unit (H1) and the second light-emitting unit (H2).
