摘要： There is provided an image processing apparatus for describing a real image as a virtual object using space data formed based on a photo image of the real object, and generating a virtual image of the virtual object using the space data. The image processing apparatus captures the photo image of the real object from a real camera viewpoint position while illuminating the real object by an illumination light source placed at a real illumination position. The captured photo image is converted into space data in the form of an object for each pixel, and the space data is stored in a memory together with various illumination conditions at the real illumination position to allow a search at a later time.

摘要： In an image reproducing method capable of displaying annotations in virtual space constituted by a group of real panoramic images. If an object for which an annotation is to be displayed falls within the field of view at the position of the observer, the object is adopted as the display position of the annotation. If the object is not within the field of view, then the direction of forward travel of the observer is adopted as the annotation display position. If the object is in a state of transition, then the annotation display position is decided by interpolation.

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： By applying identification processing to each index included in a captured image, a set of an identifier, image coordinates, and an image number is acquired for each index, and the acquired set is registered in a data saving unit. The data saving unit manages the numbers of times of previous identification for respective identifiers. A display unit displays the number of times managed in association with an identifier in a set to be registered every time the set is registered. An index position and orientation calculation unit calculates the positions and orientations of indices corresponding to a set group using the set group registered in a memory.

摘要： Plural pieces of frame data are generated and held based on image data obtained by capturing images while moving a plurality of capture devices for capturing images in different directions. A frame data group containing consecutive pieces of frame data determined to have been captured at practically the same position can be extracted from the plural pieces of held frame data. Frame data is deleted from the extracted frame data such that one piece of frame data can exist as the data captured at one position. Thus, when the frame data corresponding to a plurality of positions on a map is stored, thinned frame data is stored after being associated with the corresponding position on the map. Therefore, when virtual space in a walk-through system is designed using an IBR technology, panoramic images for reproduction of the virtual space can be efficiently generated and held.
