摘要： In position and orientation measurement based on natural features, erroneous detection of the natural features is prevented when an observation target object is occluded by another object, and registration stability is improved. To this end, an occluding object that can occlude the observation target object is defined, and an occluding region where the occluding object occludes the observation target object is detected in an input captured image. Image features of the observation target object are detected in a region of the captured image other than the detected occluding region. Therefore, the position or orientation of an image pickup apparatus that captured the captured image, or the position or orientation of the observation target object in the captured image are calculated.

摘要： Indices allocated or set on an object are detected from sensed images of frames, which are time-serially sensed by an image sensing device. In association with each index detected from the sensed image of the frame of interest, a detection condition from frames before the frame of interest is acquired. According to the acquired detection condition of the index, the reliability of this index is calculated. The position and orientation of the object or the image sensing device are calculated using at least information associated with the image coordinates of the detected indices and the reliabilities of the indices.

摘要： A marker placement information estimating method includes a constraint condition setting step for setting a constraint condition that can be defined with a geometric condition regarding placement information of markers, a capturing step for capturing photographed images including a marker image, a marker detecting step for detecting markers from the photographed images, and an estimating step for estimating the placement information of the markers using the positions of the detected markers on the images and the constraint condition. Thus, even if a constraint condition regarding the placement of markers exists, the placement information can be obtained with precision so as to satisfy the constraint condition.

摘要： A position and an orientation of an image capturing device or an object to which an inclination sensor is mounted are obtained without performing iterative calculation. A position and orientation measuring method includes the steps of: inputting a measured inclination value of an inclination sensor mounted to one of an object and an image capturing device; inputting a captured image from the image capturing device; detecting an index on the object from the captured image; and calculating a position and an orientation of one of the object and the image capturing device to which the inclination sensor is mounted on the basis of the measured inclination value, an image coordinate of the detected index, and already-known positional information on the detected index without performing iterative calculation.
