    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: An index layout measurement method and apparatus measures a relative layout relationship between a first index or index group which exists in a given first region in a physical space and a second index or index group which exists in a second region. The method includes a first image sensing step of sensing an image so as to simultaneously include some or all of the first index/index group and an auxiliary index which is temporarily laid out in the physical space and a position and orientation in a three-dimensional space of which can be defined, a second image sensing step of sensing an image so as to simultaneously include some or all of the second index/index group and the auxiliary index, and a layout calculation step of calculating a relative layout relationship among the first index/index group, the auxiliary index, and the second index/index group from one or a plurality of images obtained by performing the first image sensing step once or repeating it a plurality of number of times, and one or a plurality of images obtained by performing the second image sensing step once or repeating it a plurality of number of times. The auxiliary index is removed after the layout relationship among the respective indices laid out in the physical space is calculated.

    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.
