摘要： The invention provides a method for generating a three-dimensional model by modifying a standard model based on measured data without causing a topical improper modification. In the method, it is decided whether to further modify the standard model or to finish the modification of the standard model based on integrated evaluation of two or more functions selected from a first function relating to a distance between the standard model and the measured data, a second function relating to a distance between a characteristic point defined on the standard model and a characteristic point specified on the measured data and corresponding to the characteristic point defined on the standard model and a third function relating to a distance between an outline defined on the standard model and an outline specified on the measured data and corresponding to the outline on the standard model.

摘要： The present invention provides a method for fitting a surface to a point group using computer. The method enables to prevent an improper modification or an erroneous modification even when the point group includes a point having a low reliability, thus to achieve proper modification. The method comprises a first step for judging reliability of each of points composing the point group and a second step for changing the method for fitting the surface to the point group based on the result of judgment of the first step. In the second step, the method for fitting is changed by varying weights of the points based on the reliabilities.

摘要： A method and an apparatus are provided for merging two meshes whose density differs from each other so as to avoid unnatural appearance. A first mesh and a second mesh that differ from each other in density are merged by the following procedure. Edge length of a portion that becomes a boundary between the first and second meshes is determined, size of a first group of polygons including the edge of the portion is determined based on the determined length and size of a second group of polygons is adjusted so that an adjustment ratio is smaller as a distance between a position of each of the second group of polygons and the portion is greater, the first and second group of polygons being part of polygons structuring the first and second meshes, and the first and second meshes in each of which the polygons are adjusted are merged.

摘要： An object of the present invention is to automatically determine the orientation of a newly generated surface, etc. when performing such processing as filling a dropout portion of three dimensional shape data, and to generate more natural three dimensional shape data. The present invention provides a method for generating a grid-patterned surface in three dimensional shape data, and comprises a first step (#11) for detecting the orientation of a polygon in the three dimensional shape data that is located at a periphery of a surface to be fitted, a second step (#12) for determining the orientation of the surface so that a grid orientation of the surface matches the orientation of the detected polygon, and a third step (#13) for fitting the surface onto the three dimensional shape data while maintaining the thus determined orientation.
