摘要： The first values of position and orientation of an image sensing device are obtained by using positions of all indices in a frame image. Indices having the same inherent information between a first index group (FIG) in the frame image and a second index group (SIG) in a preceding frame image are detected as a common index. If the information of the SIG contains information different from that of the FIG, second values of the position and orientation are obtained by using the positions of the common indices in the preceding frame image. If the information of the FIG contains information different from that of the SIG, third values of the position and orientation are obtained by using the positions of the common indices in the frame image. The first values are corrected by using correction values based on the obtained first to third values.

摘要： When a calibration jig (50) which includes an image sensing device (100) is moved within the image sensing range of an image sensing device (200), the image coordinates of an index (110) on the image sensing device (100) in a plurality of images sensed by the image sensing device (200) are extracted. The image coordinates of environment allocation indices (300) in a plurality of images sensed by the image sensing device (100) are extracted. An information processing apparatus (1000) calculates camera parameters of the image sensing device (200) based on the extracted image coordinates of the index (110) and the environment allocation indices (300).

摘要： An index detection unit (2030) detects indices allocated or set on an object from a sensed image. An evaluation amount calculation unit (2060) calculates evaluation amounts of the indices using two-dimensional geometric features of the indices on the image and/or three-dimensional geometric features that represent relationships between an image sensing device (2010) and the indices on a three-dimensional space. A reliability calculation unit (2070) calculates reliabilities of the indices according to the calculated evaluation amounts of the indices. A position and orientation calculation unit (2080) calculates the position and orientation of the object or the image sensing device (2010) using at least the calculated reliabilities of the indices and information associated with the image coordinates of the detected indices.
