摘要： PROBLEM TO BE SOLVED: To provide generation technology of a curved surface model in which advantages of both of a modeling method by distance image data and a modeling method by silhouette data are utilized as using photographic and measurement data from a small number of viewpoints. SOLUTION: A curved surface model generating part 30 inputs 2D color image data 41 and distance image data 42. When silhouette image data 44 is extracted from the 2D color image data 41, initial model data 47 is generated by using a Volume Intersection method, etc. The distance image data 42 is converted into a world coordinate value by using photographic position/attitude data. In a fitting processing part 35, evaluation in consideration of conformity by using distance with distance image data 45 as a yardstick and using distance with the silhouette data 44 as the yardstick is performed, curved surface model data 49 is generated by fitting a curved surface to the initial model data.

摘要： PROBLEM TO BE SOLVED: To provide a stereoscopic chart, a parameter acquisition method, and an information processing device capable of widely correcting a camera with high accuracy. SOLUTION: Unit figures whose sizes are encoded at different ratios are formed on the sides of a stereoscopic chart 2. The ratios of the unit figures are calculated on the basis of the picked-up image of the stereoscopic chart 2, and the calculation result is collated with an actual value by which the position and attitude of an image pickup point are obtained. The moving average of the height of the unit figures is set nearly proportional to a distance from an apex, and a limitation imposed on an image pickup distance can be reduced. A movable camera 11 is mounted on an image pickup camera 13, and the stereoscopic chart 2 is imaged at the same time when the image of an object 30 is picked up. The position and attitude of the camera 11 are obtained on the basis of the image of the chart 2 picked up by the camera 11 through the above procedure, and the position and attitude of the object imaging camera 13 are found on the basis of a positional and attitude relation between the cameras 11 and 13, where the above relation is previously obtained.

摘要： PROBLEM TO BE SOLVED: To generate one stereoscopic model that properly represents face figures of a plurality of people. SOLUTION: In the case of generating one stereoscopic model representing face figures of a plurality of people, the stereoscopic model generating device measures faces one by one person and sequentially generates a three-dimensional model of the face of each person through a prescribed data processing (steps ST18, ST20, ST27). Then the stereoscopic model generating device synthesizes these three-dimensional models into one three-dimensional model after that and generates a stereoscopic model on the basis of the synthesized three- dimensional model. Thus, the resolution and the measurement range of a three- dimensional measurement device can stimulatingly be improved and one stereoscopic model properly representing face figures of a plurality of people can be generated.

摘要： PROBLEM TO BE SOLVED: To provide a three-dimensional shape data processor without being affected by fluctuation in an illuminating state to an object article and without influence of a change in color of a hair when the article is a human head. SOLUTION: Immediately after a power source is turned on, a color image for a calibration is photographed, and a luminance image for the calibration is stored in a memory 403b. In order to guide user guest's had shape data (three- dimensional shape data DM), color image data DC is input by a two-dimensional camera, and distance image data DS is input by a three-dimensional measuring device. Luminance image (input luminance image) is generated from the data DC in a luminance image generator 402, and a change ratio of the illuminating state is obtained from the luminance image for the calibration and the input luminance image in a luminance change ratio calculator 403, and a correcting unit 404 corrects the input luminance image in response to the change ratio.

摘要： PROBLEM TO BE SOLVED: To reduce influence owing to error even if a hair part in a picture obtained on an object is erroneously judged. SOLUTION: A picture obtained on a prescribed object like (a) is divided into plural areas RA, RB and RC at every continuous set on pixels whose picture features are similar like (b). Similarity to the specified area RA among the plural areas is obtained at every pixel. The similarity of an oblique line part (part equivalent to specified area RA) of (c) becomes considerably high compared to the other part. Similarities of the pixels contained in the specified area respectively differ. When data corresponding to the pixels is worked while a work degree is adjusted in accordance with similarity, influence to data work is reduced even if the area is erroneously divided.

摘要： PROBLEM TO BE SOLVED: To provide a three-dimensional piece forming device which requires a short time for processing. SOLUTION: A three-dimensional piece forming device measures the three- dimensinal data for a three-dimensional piece, processes the work on the basis of the obtained shape data, and produces a three-dimensional duplicate, whereby the measured three-dimensional shape data is compressed in the specified direction (for example, in the depth direction) and the material is processed according to the compressed shape data so that the intended three-dimensional piece is yielded. Compression of the data in the depth direction lessens the part to be processed and shortens the time for processing. In a three-dimensional object preparing device in which specified shape data is synthesized in the backdrop part, the processing time of the part having an extraordinarily large depth is shortened through transformation of the date specifically (into shallow data).
