According to a certain aspect of the present invention, a control device for a robot is provided. The control device includes a processor configured to implement: a function of obtaining a signal indicating a detected value of a sensor detecting a state quantity of the robot; and a function of, in converting the detected value to an estimated value of the state quantity according to a conversion function obtained by calibration of the sensor, applying an offset value compensating for a difference between the estimated value and the actual state quantity in a critical situation in operation of the robot.

Robot control apparatus, control method and control program

A mat for an image pickup apparatus, where the image pickup apparatus operates to recognize a real object, the mat includes: a play field that defines a bottom region of a space in which the real object is placed; and a calibration chart located in the space and having a plurality of color regions in which respective luminances thereof differ from one another, where: the image pickup apparatus: (i) obtains data of a picked up image of the space in which the real object is located; and (ii) evaluates the picked up image and adjusts at least one of an image pickup condition in which the picked up image of the space is taken, and a processing condition in which the data are analyzed to recognize the real object, and at least one of the image pickup condition and the processing condition are adjusted based on color information in the data of the picked up image resulting from the plurality of color regions of the calibration chart.

Image pickup apparatus, information processing system, mat, and image generation method

In an information processing system, an information processing apparatusrecognizes, when a user moves real bodiesandarranged on a play field, the movement on the basis of, for example, an image taken by a camerataking an image of the movement to interlock objects of corresponding charactersanddisplayed on a display apparatus. In addition, when the user moves the charactersandthrough an input apparatus, the information processing apparatustransmits a control signal to the corresponding real bodiesandto perform interlocking. When a situation in which interlocking between the real bodiesandand the charactersandis difficult occurs, an appropriate scenario is selected from the scenarios prepared in advance and realized, thereby maintaining the consistency.

Information processing apparatus, information processing system, and information processing method

An image of a block or the like entering a space above a play mat is picked up by an image pickup apparatus, and an information processing apparatus detects and recognizes the block on the basis of a picture of the block in a picked up image and performs information processing. The play mat includes a play field that defines a detection space for the block, and a calibration chart including at least a plurality of regions of colors of different luminances. The image pickup apparatus adjusts an exposure time period, a gain value for each color component and a correction rule upon gamma correction on the basis of the picture of the calibration chart in the picked up image.

A block set assembled by a user and an information processing device communicate with each other. The information processing device thereby obtains information on the structure of the block set. In addition, an object of a crane truck corresponding to the block set is displayed on a display device. Correspondences between joints and wheels and correspondences between movements are set. Thereby, when the block set is moved, the movement of the block set is reflected in the object on display. When the object is moved, the movement of the object is reflected in the block set by transmitting a control signal from the information processing device.

On a play fieldset in real space, a target regionhaving the play fieldas a bottom surface and having a predetermined height h is set virtually. A target region image that expresses a distance of the target regionfrom an imaging surface as a pixel value on an image plane is generated, and compared with a depth image corresponding to an actual captured image; thus, only images of blocksandinside the target regionare extracted as detection and tracking targets.

Information processing device and information processing method

By extracting figures of a play field and a display apparatus from a taken image, the positional coordinates of the play field and a screen in a world coordinate system are obtained. Next, a virtual world is built such that the ground of the virtual world is positioned continually flush with the surface of the play field in a real world, on the opposite side of the real world with the screen in between in a virtual space defined in the world coordinate system. Then, a virtual viewpoint is placed at a position corresponding to the viewpoint of a user in a real space so as to generate an image with the virtual world projected to the screen on the basis of this virtual viewpoint as a display image.

Information processing apparatus and information processing method

A core information receiving section of an information processing device receives information related to the state of a core from a first block of a block set assembled by a user. A structure analyzing section identifies the shape, posture, and position of the block set on the basis of an image photographed by a camera and the information related to the state of the core. An information processing section performs predetermined information processing according to the shape, posture, and position of the block set or an operation on an input device by the user. A display processing section generates an image to be displayed as a result of the information processing, and outputs the image to a display device. A driving control section transmits a signal for controlling the operation of the block set.

Information processing device, information processing system, block system, and information processing method

An information processing device communicates with a block set assembled by a user, and thereby obtains information on the structure of the block set. In addition, a corresponding position setting screen including an image of an object corresponding to the block set is displayed on a display device. The user moves a joint of the block set which joint is desired to be associated, by for example bending and stretching the joint. Next, the user indicates a joint to be associated on a 3D object side in the image of the 3D object by a cursor, and performs a determination input. The joint of the block set and the joint of the 3D object are thereby associated with each other. The block set and the object are interlocked with each other bidirectionally by thus setting the corresponding positions of the block set and the object.

A block tool, which can be assembled by a user, is configured with multiple types of blocks and is shot by a camera for capturing a still image or a moving image. The position coordinates of a marker of the square-pillar block in a three-dimensional space are obtained by image recognition. Also, a connecting position and the type of each block, a gradient vector of the square-pillar block, an angle between two blocks constituting the square-pillar block, and the respective blocks' lengths are obtained so as to derive the shape, posture, and position of the block tool, and corresponding information processing is then performed.
