  • Publication number: 20130329942
    Abstract: A pattern light projection unit which stores information on pattern light including information on line patterns projects pattern light including line patterns having at least two lines and at least one reference line pattern serving as a reference of the line patterns on an object in accordance with the information on pattern light. An image pickup unit captures an image of the object to which the pattern light is projected. An information processing apparatus detects the reference line pattern and the line patterns from the captured image, and establishes correspondence between the information on the line patterns stored in the pattern light projection unit and the line patterns detected from the captured image in accordance with the topological positional relationship between the detected reference line pattern and the line patterns so as to identify the line patterns.

  • Publication number: 20130229666
    Abstract: A projection pattern that includes a measurement pattern for measuring a distance to a target object, and a code pattern for identifying the measurement pattern is projected onto the target object. The target object onto which the projection pattern was projected is sensed. On the basis of a relationship between the measurement pattern and the code pattern in the sensed image, the projection pattern that is to be projected onto the target object after the projection pattern are changed, the code pattern is read out in the sensed image of the target object onto which the changed projection pattern was projected, and the measurement pattern is associated with it. Using the associated measurement pattern, a distance from the projection unit or the sensing unit to the target object is acquired.

  • Publication number: 20130156268
    Abstract: An image information processing apparatus performs three-dimensional measurement of an object using a captured image obtained by projecting onto the object a projection pattern containing a two-dimensional symbol sequence that is obtained by assigning a predetermined symbol to each code in a projection code string in which a plurality of types of codes are arranged two-dimensionally and capturing an image of the object. The apparatus obtains an imaging pattern by extracting a symbol sequence from the captured image, and converts symbol dots in the imaging pattern into corresponding codes, thereby obtaining an imaging code string. The apparatus obtains a predetermined number of codes according to one sampling feature selected from a plurality of types of sampling features, generates an information code string by arranging the obtained codes, and determining the correspondence between the information code string and a part of the projection code string, thereby performing three-dimensional measurement.

  • Publication number: 20080094351
    Abstract: A plurality of stimulus generators (110), which is used to apply stimuli to the human body, and is laid on the human body of the user, is controlled. A position determination unit (108) determines whether or not a virtual object that forms a virtual space where the user exists is in contact with the human body. When the contact has occurred, a control unit (103) executes drive control of each of a plurality of stimulus generators (110), which are located near a place where the contact is determined, based on the positional relationship between the virtual object and the stimulus generators.
