  • Patent number: 10189162
    Abstract: A three-dimensional shape model of a target object is input. A position and orientation of at least one image sensing device used to capture an image of the target object is set so as to virtually set a relative position and orientation between the target object and the image sensing device for the three-dimensional shape model of the target object. At least one position and orientation of the image sensing device is selected. Geometric features are grouped based on a relationship between an image to be obtained at the selected position and orientation of the image sensing device and the geometric features of the three-dimensional shape model.

  • Patent number: 10140723
    Abstract: An index detecting section detects an index in a physical space, from a captured image obtained by an imaging apparatus. An erroneous-detection prevention processing section performs erroneous-detection prevention processing, based on information relating to image coordinates of a detected index. An image output section outputs, to a display device, an image having been subjected to the erroneous-detection prevention processing. This prevents an image displayed on the display device from being mistaken for a real index when the display device is in the field of view of the imaging apparatus.

  • Patent number: 9733339
    Abstract: A position and orientation measuring apparatus calculates a difference between an image feature of a two-dimensional image of an object and a projected image of a three-dimensional model in a stored position and orientation of the object projected on the two-dimensional image. The position and orientation measuring apparatus further calculates a difference between three-dimensional coordinate information and a three-dimensional model in the stored position and orientation of the object. The position and orientation measuring apparatus then converts a dimension of the first difference and/or the second difference to cause the first difference and the second difference to have an equivalent dimension and corrects the stored position and orientation.
