摘要： PROBLEM TO BE SOLVED: To provide a data processing technology by which information profitable for obtaining new partial shape measurement data can be achieved when generating a three-dimensional shape model based on a plurality of partial shape measurement data. SOLUTION: Contributing point showing conformity with a silhouette image is added onto respective vertexes of the three-dimensional shape model MB generated based on the silhouette image of a subject photographed from viewpoints P1 to P3. That is, the contributing point is added onto points M2, M4, M6, M8 and M10 on the outline of the silhouette image photographed and obtained from the respective viewpoints, and the contributing point is not added to other points. When the silhouette image is newly photographed, an image whereby the contributing point of the three-dimensional shape model MB is visualized is displayed together with a preview image of the subject. A user recognizes the image information, and thereby a new silhouette image can be achieved from a viewpoint Pm different from the silhouette image achieves previously. Thus, the three-dimensional shape model MB can be effectively generated. COPYRIGHT: (C)2003,JPO

摘要： PURPOSE: To make it possible to input manually with ease corresponding points of a plurality of three-dimensional data inputted from a multiplicity of viewpoints, by specifying corresponding points on a picture image on a two-dimensional picture data memorized so as to correspond to the data expressing a three-dimensional shape. CONSTITUTION: Concerning picture images derived from a sensor 12 for distance picture images, subtraction is implemented between a picture image 18a derived when slit light is projected and a picture image 18b derived when slit light is not projected, and then incident light quantity centroid position computation processing 19, distance information computation processing 20, and distance picture image production processing 21 are implemented. A three-dimensional distance picture image thus obtained is outputted to an output terminal 50 via NTSC conversion processing 27, or else transmitted to an SCSI terminal 49 and to a recording device 22. Meanwhile, a picture image derived from a sensor 24 for color picture images is given two-dimensional color picture image production processing 26 via analog processing 25. A two-dimensional color picture image thus obtained, being given NTSC conversion processing 28, is outputted for utilization to an output terminal 51, or else transmitted as digital data to the SCSI terminal 49 and to the recording device 22.

摘要： PURPOSE:To combine images at a relatively low cost by calculating a relative positional relationship of images from a plurality of image data, obtaining a parameter for coordinate transformation based on the relationship, and transforming coordinates before combine the images. CONSTITUTION:A two-dimensional color image, three-dimensional data, a focal length and a distance to a reference surface are taken from photographed data. A connecting point is searched from the two-dimensional color image. Supposing that the connecting point is searched within one pixel from the color image, the three-dimensional data is then used to search for the connecting point by a smaller degree than one pixel. A rotary angle of a camera (panning angle, tilt angle) is calculated from the connecting point of the two-dimensional image, focal length and distance to the reference surface. A parameter for coordinate transformation in a three-dimensional space is calculated from the rotary angle. It is searched where an evaluation value which is a square sum of an angle defined by normal lines of two planes passing the connecting point is minimum. If the evaluation value is not larger than a given value, the last parameter is used to convert and combine two three-dimensional images in the same coordinate system, thus completing the operation.

摘要： PROBLEM TO BE SOLVED: To provide a data processing technology capable of suitably positioning a three-dimensional shape model generated based on a plurality of partial shape measurement data and a partial shape separately measured. SOLUTION: Contributing point showing conformity with a silhouette image is added onto respective vertexes of the three-dimensional shape model MB generated based on the silhouette image of a subject photographed from viewpoints P1 to P3. That is, the contributing point is added on points M2, M4, M6, M8 and M10 on an outline of the silhouette image photographed and obtained from the respective viewpoints P1 to P3, and the contributing point is not added to other points. When the silhouette image is newly photographed, the new silhouette image and the three-dimensional shape mode MB are aligned except for the points to which the contributing points are not added. Accordingly, other partial shape data can be suitably aligned with respect to the three- dimensional shape model. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To reduce of erroneous correspondence in a search of a corresponding point between two images.
SOLUTION: Link edges of a left image 210 and a right image 220 photographed on a same object are extracted from a link edge extracting part 141, and are made as left edge data 221 and right edge data 221. Scanning lines in upper and lower end positions of the respective link edges are set as a boundary scanning line by a link edge grouping part 142, and both of the images are divided into a plurality of areas with the boundary scanning line as a boundary. Then, a corresponding point search by dynamic programming of two stages is conducted in the respective divided areas by a corresponding point searching part 143. Thereby, correspondence of all of the link edges can be used as a restricting condition, and the occurrence of the erroneous correspondence is reduced.

摘要： PROBLEM TO BE SOLVED: To generate three-dimensional shape data of a small data quantity in the state of holding a featured line desired by a user from a three-dimensional model to be an object. SOLUTION: With respect to three-dimensional shape data, a closed and curved face virtually formed by plural vertical lines BCM and plural horizontal lines BCP is arranged so as to enclose a shape model, and the vertical lines BCM and the horizontal lines BCM are projected to the surface of the shape model toward an axis so as to generate the parametric curve group BCG 2 along the surface of the shape model. Then the parametric curve group BCG 2 is corrected so that the part of the parametric curve group BCG 2 corresponding to the movement of a control point is moved along the surface of the shape model when moving the control point of the parametric curve group BCG 2, and data on the corrected parametric curve group BCG 2 is set to be three- dimensional data of the shape model.
