  • Publication number: 20220184489
    Abstract: An input device includes a case body and a plurality of markers 30d, 30e, and 30p configured to emit light to the outside of the case body.

  • Publication number: 20220021798
    Abstract: An information processing apparatus acquires, using an image obtained by capturing a device including a light-emitting marker with exposure times shorter than a time corresponding to one frame, information regarding a position and a posture of the device. The light-emitting marker is caused to emit light for light emission times equal to or shorter than the exposure times. The information processing apparatus causes the light-emitting marker to emit light in a predetermined flashing pattern, and identifies the exposure times on a time axis of the device on the basis of whether or not the image appears in the captured image, to thereby synchronize the exposure and the light emission.

  • Patent number: 11227408
    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.

  • Publication number: 20200342624
    Abstract: An information processing apparatus includes a captured image acquisition unit that acquires an image captured by imaging a device including plural markers. A marker image coordinate specification unit specifies a representative coordinate of each marker image from the captured image, and a position and posture derivation unit derives position information and posture information of the device using the representative coordinates of the marker images. The marker image coordinate specification unit specifies a first boundary box surrounding a region within which pixels having a first luminance or more continuously appear, specifies a second boundary box surrounding a region within which pixels having a second luminance or more continuously appear in the first boundary box, the second luminance being higher than the first luminance, and derives a representative coordinate of each marker image based on pixels in the first or second boundary box in response to the number of specified second boundary boxes.
