摘要： Each of the panoramic images corresponding to a plurality of positions of a viewpoint is compressed and stored as partial images obtained by dividing each panoramic image by a predetermined field of view. The panoramic image has a field of view wider than a display field of view of an image to be displayed on a display unit. A partial image containing an image to be reproduced is selected based on the information about the position and the direction of a viewpoint and the display field of view, and an image corresponding to the position and the direction of a viewpoint is generated and displayed from the selected partial image. Thus, when virtual space in the walk-through system is designed using the IBR technology, stored image data can be efficiently reproduced.

摘要： There is disclosed an image data encoding/decoding method and apparatus which can efficiently encode multi-viewpoint image data obtained by sensing a single object from many viewpoints, and can obtain decoded data in units of pixels at high speed. Reference images which are not encoded are set every predetermined number of images (S701), and encoding is done using only the relationship with this reference image. An orthogonal transform is used in encoding, and an inverse transform formula for each pixel in a block is expanded and stored upon computing the orthogonal transform (S704). The coefficients after the orthogonal transform are fixed-length encoded in units of pixels (S705). Upon decoding, fixed-length encoded data corresponding to desired pixels are decoded, and pixel data are decoded by substituting coefficients obtained by decoding in the expansions generated upon encoding.

摘要： From a sequence of images captured by an image pickup unit, images necessary for measuring placement information regarding markers and/or a sensor are automatically determined and obtained. To this end, using position and orientation information regarding the image pickup unit at the time the image pickup unit has captured an obtained image and placement information regarding detected markers, whether to use the captured image corresponding to the position and orientation is determined. Using the captured image determined to be used, the marker placement information, placement information regarding a measurement target, or the position and orientation of the image pickup unit serving as an unknown parameter is obtained so as to minimize the error between the measured image coordinates and theoretical image coordinates of each marker, which are estimated on the basis of a rough value of the parameter.
