摘要： In order to simplify a photographing operation when providing a texture original image, and to remove a useless operation when extracting a necessary region from the texture original image, the necessary region is assigned in an original image, serving as a base for a texture, using characteristic points of a portion onto which the texture is to be mapped, and a quadrangle having a minimum area is extracted from among quadrangles enclosing the assigned region. An image enclosed by the extracted quadrangle is transformed into a rectangular image having a desired size, and the assigned region is transformed into a region in the rectangular image. The obtained rectangular image and data of the characteristic points for assigning the region are output as texture data. In order to automatically correlate the positions of points assigned in a polygon image with the positions of points assigned in the texture original image including a necessary texture image, respective vertices of the polygons of the displayed polygon image and corresponding points in the displayed texture original image are assigned. Thus, the texture image including the corresponding points is obtained, and position information of the corresponding points in the texture image is provided for the respective vertices assigned in the polygon image.

摘要： Whether or not an object to be rendered in stereo images is inside of a fusional area is determined on the basis of a focus point and positions of eyes of a viewer. By using characteristics of a view sight of a human in which an object in a fusional area of human eyes can be clearly recognized as a single solid, however, if an object is not in the fusional area, the object is recognized as vague overlapped images, an object which is inside of the fusional area is rendered by using an image generating algorithm capable expressing in high precision. In contrast, an object which is outside of the fusional area is rendered by using an image generating algorithm which requires lighter calculation load than the former image generating algorithm.

摘要： A two-dimensional data generator and a 2D display controller display a two-dimensional plane image based on three-dimensional data read by a three-dimensional data reading unit. A texture amount calculator calculates a texture amount used in rendering a three-dimensional image based on the three-dimensional data at each of a plurality of viewpoints set in the two-dimensional plane. A texture amount exceeding position display controller clearly displays a viewpoint where the calculated texture data amount exceeds a predetermined value in the two-dimensional plane. A texture amount adjusting unit adjusts the data amount of a desired texture.

摘要： An image processing method and the apparatus thereof for approximating an object shape and reconstructing the corresponding image by subjecting a radial range image to approximating with polygons and reconstructing an image from these polygons execute the following processes. At block B210, reading a radial range image data is executed. At block B220, a plural of different resolution radial range images are generated based upon the read radial range image. At block B230, normal vectors, according to each resolution of a radial range image, are calculated. At block B240, an edge-map having a plural of edges is generated in such a manner that a plural of edges are generated depending upon the resulting normal vectors and the radial range images of different resolutions. At block B250, the edge-maps of all kinds of resolutions are ORed to form a synthesized map. The synthesized map is subjected to correcting crossing and isolated edges. At block B260, each polygon is divided into a plural of triangles. At block B270, assigning 3 dimensional coordinate values and the normal vector generated at block B230 to each apex and the corresponding triangle plane respectively, is executed. At block B280, eliminating unnecessary triangle gaps around a T-shaped point is executed.

摘要： A view transformation matrix that represents the position/attitude of an HMD is generated based on a signal that represents the position/attitude of the HMD (S602). On the other hand, landmarks and their locations are detected based on a captured picture (S604) and a calibration matrix ΔMc is generated using the detected locations of the landmarks (S605). The position/attitude of the HMD is calibrated using the view transformation matrix and calibration matrix ΔMc generated by the above processes (S606), a picture of a virtual object is generated based on external parameters that represent the position/attitude of the calibrated HMD, and a mixed reality picture is generated (S607). The generated mixed reality picture is displayed in the display section (S609).
