Information processing apparatus, device speed estimation method, and device position estimation method

An input device includes a case body, a plurality of markers configured to emit light to the outside of the case body, and an indicator configured to indicate the state of the input device. A control portion lights the plurality of markers at predetermined intervals, and lights the indicator in a period during which the plurality of markers are unlit.

Device including plurality of markers

An input device includes a case body and a plurality of markers configured to emit light to the outside of the case body. A first light source is a dedicated light source for lighting one marker, and a second light source is a shared light source for lighting a plurality of markers. The second light source is connected to a plurality of markers with a light guide pipe so as to supply light to the plurality of markers through the light guide pipe.

An input device includes a case body and a plurality of markers, andconfigured to emit light to the outside of the case body. When an angle difference between the normal directions of the two markersandis less than a predetermined threshold value, a distance between the two markersandis equal to or greater than a predetermined first distance. When an angle difference between the normal directions of the two markersandis equal to or greater than a predetermined threshold value, a distance between the two markersandis equal to or greater than a predetermined second distance, and the second distance is shorter than the first distance.

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.

Information processing apparatus, information processing system, device for position and posture acquisition, and device information acquisition method

A captured image acquisition unit acquires an image obtained by capturing a first device that includes a plurality of markers and a second device that includes a plurality of markers. An estimation processing unit first derives position information and posture information of the first device on the basis of marker image coordinates in the captured image and then derives position information and posture information of the second device on the basis of remaining maker image coordinates excluding marker image coordinates of the first device.

Information processing apparatus and device information derivation method

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.

Marker-based tracking apparatus and method

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.

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.
