Patent number: 7123254Abstract: 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.Type: GrantFiled: June 29, 2001Date of Patent: October 17, 2006Assignee: Minolta Co., Ltd.Inventors: Osamu Toyama, Eiro Fujii, Tomasz Kowalczyk, Shinichi Horita

Publication number: 20060071930Abstract: When volume data of a three-dimensional object to be processed is read and stored into a predetermined storage, first, a plurality of reference planes are set and a plurality of reference distance maps each indicative of distribution of distances between the three-dimensional object and each of the reference planes are generated. Next, when an actual projection plane onto which the three-dimensional object is projected in the volume rendering is set, two or more distance maps out of the plurality of reference distance maps are converted into two or more converted distance maps in accordance with a positional relation between two or more reference planes corresponding to the two or more distance maps and the actual projection plane, and integrating the resultants, thereby generating a distance map for visualization indicative of distribution of distances between the three-dimensional object and the actual projection plane.Type: ApplicationFiled: October 4, 2005Publication date: April 6, 2006Inventors: Koichi Fujiwara, Osamu Toyama

Publication number: 20060066611Abstract: A virtual plane of projection on which a virtual three-dimensional object constructed by a set of specific structures oriented in predetermined directions is projected is set. First, while generating a basic image by projecting one specific structure oriented in a predetermined direction onto the virtual plane of projection, a reference image position corresponding to a reference position of the one specific structure in the basic image is recognized. At the time of projecting a virtual three-dimensional object onto the virtual plane of projection, each of reference projection positions in which the reference positions of specific structures constructing the virtual three-dimensional object are projected is detected. Further, by combining adjusted basic images generated by adjusting the positions of the basic images relative to the virtual plane of projection in accordance with the reference projection positions, a display image is generated.Type: ApplicationFiled: September 14, 2005Publication date: March 30, 2006Inventors: Koichi Fujiwara, Osamu Toyama

Publication number: 20060056726Abstract: The present invention provides a technique capable of making a user easily grasp a relative position of an ROI in image display by volume rendering and capable of displaying an image promptly. Upon generating an image for display on the basis of volume data by volume rendering, a region of interest (ROI) in a three-dimensional region corresponding to volume data is designated. A first display image portion of the ROI is generated by a normal computing method of a relatively large computation amount. On the other hand, a second display image portion of the region other than the ROI is generated by a simplified computing method of a relatively small computation amount.Type: ApplicationFiled: August 15, 2005Publication date: March 16, 2006Inventors: Koichi Fujiwara, Osamu Toyama

Patent number: 6992665Abstract: 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.Type: GrantFiled: March 26, 2001Date of Patent: January 31, 2006Assignee: Minolta Co., Ltd.Inventors: Osamu Toyama, Shinichi Horita, Eiro Fujii

Publication number: 20050017987Abstract: 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.Type: ApplicationFiled: November 20, 2003Publication date: January 27, 2005Inventors: Shinichi Horita, Koichi Fujiwara, Eiro Fujii, Koji Fujiwara, Osamu Toyama

Patent number: 5355205Abstract: An image forming apparatus provided with a plurality of sheet supply inlets respectively accommodating different kinds of sheets and a selecting member for selecting a desired kind of sheets. When a desired kind of sheets is selected by the selecting member, a check is made to determine whether the presently selected sheets are the same kind, for example, the same size, as the sheets which have been selected prior to the operation of the selecting member. When the presently selected sheets are the same kind as the sheets selected prior to the operation of the selecting member, the apparatus is controlled so that a sheet supply inlet accommodating the same kind of sheets as the sheet selected prior to operation of the selecting member but different from the sheet supply inlet used for sheet supply prior to the operation of the selecting member, for example, a sheet supply inlet in which the same kind of sheets are oriented in a different direction, is selected.Type: GrantFiled: February 12, 1993Date of Patent: October 11, 1994Assignee: Minolta Camera Kabushiki KaishaInventors: Osamu Toyama, Kadotaro Nishimori
