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.

    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： Upon observation of multi-viewpoint images, even when the viewpoint moves continuously, the image cannot normally be displayed in correspondence with the continuous movement of the viewpoint, and an image from a viewpoint closest to the current viewpoint is displayed. To prevent this, each two adjacent images of the multi-viewpoint images are interpolated by detecting corresponding pixels and generating an interpolated image in accordance with the correspondences among pixels. The interpolated image is generated in such a manner that an epipolar plane image is generated by juxtaposing corresponding lines of the multi-viewpoint image, straight lines are detected from the epipolar plane image, and the intersecting points between interpolated lines and the detected straight lines are detected as interpolated pixels. In this case, as for a point for which a straight line cannot be detected, a straight line passing the point is estimated, thereby generating an interpolated pixel. When a plurality of straight lines are detected for a pixel of interest, the priority level is assigned to the pixel of interest in correspondence with the number of detected straight lines. When the priority level is smaller than that of another pixel through which the detected straight line passes, the straight line is ignored, and an interpolated pixel is not generated.
