摘要： When a scanning start position set signal is input in an area image sensor, the content is transferred to a vertical scanning circuit, and the scan start position is set. Image of a desired row is read by horizontal scanning. Then, one shift signal for vertical scanning is input, the position of scanning is shifted by one row, and horizontal scanning is performed. Thus image of the next row is read. By repeating this operation, a desired strip-shaped image is read. The shape of the object is determined and when a portion is determined to have complicated shape, the image data is input by means of a lens having long focal length, and image data of other portions are input by means of a lens having short focal length. By putting together a plurality of input image data, image data as a whole is generated.

摘要： Method and apparatus for measuring three dimensional information of a target placed in an interior space of a rotator type mirror by using the rotator type mirror in combination with an imaging apparatus disposed with its light receiving axis aligned with a center axis of the rotator type mirror. The invention includes projecting reference light toward the rotator type mirror from a position on the center axis, and scanning the target with mirror reflected reference light that is produced by reflecting the reference light on the rotator type mirror. The invention further includes obtaining the three dimensional information of the target, based on a physical quantity corresponding to the projection angle of the reference light and on a physical quantity corresponding to the position of a projected image obtained when the mirror reflected reference light that scanned the target is captured by the imaging apparatus via the rotator type mirror.

摘要： In a processor for generating a three-dimensional form model, data MX on an object having a three-dimensional form are read, while two-dimensional color image GX1 are read in correspondence to the form data MX. Then, color boundaries are discriminated in the color image GX1, and the form data MX are thinned except portions in correspondence to the color boundaries. Thus, the amount of data is reduced without losing information on the color boundaries of the form.

摘要： In order to generate three-dimensional form data having characteristic lines desired by a user from original three-dimensional form data, a closed surface consisting of longitudes and meridians is arranged so as to inscribe a three-dimensional form model, and the longitudes and the meridians are projected to a surface of the three-dimensional form to generate parametric curves running along the surface. Then, control points of the parametric curves are moved to adjust the curves so that a part of the parametric curves in correspondence to the movement of the control point moves along the surface of the form model. The curves adjusted are taken as three-dimensional form data of the form model.

摘要： Based on the maximum value of distances between vertexes of polygons in a plurality of polygon meshes, the size of voxel is determined. Next, respective potential values for a plurality of polygon meshes are obtained on the basis of signed respective distances of voxels and a sum of the potential values is obtained as an added potential value. A polygon mesh made of an equivalent: face of the added potential value is defined as a surface mesh. Comparison between the surface mesh and the a plurality of original polygon meshes is performed, to determine respective vertexes (corresponding-vertexes) of a plurality of original meshes corresponding to each vertex of the surface mesh. The polygons of the surface mesh is divided/synthesized to obtain intermediate surface data. Referring to the original polygon meshes, respective vertexes of the intermediate surface data are moved. Composed polygon mesh data can be obtained with stability even if the original three-dimensional data have some errors, within a time of practical level, without unnecessarily high redundancy, while maintaining the accuracy and resolution of the three-dimensional multi-viewpoints data.
