摘要： A three-dimensional shape of an object is recognized by developing enveloping surfaces of the object by a cone-silhouetting method, wherein the object is picked up by a binocular three-dimensional vision method by making use of geometrical restraint conditions derived by the cone-silhouetting method. The binocular parallax is increased to thereby ensure the recognition of the three-dimensional shape with improved accuracy. Local concave portions which can not be recognized by the cone-silhouetting method by itself are recognized with higher accuracy.

摘要： A pattern processing method is provided which performs the following steps with regard to a region in an n-dimensional space: providing a procedure (relative expression procedure) for generating relative positional data of any desired point in the n-dimensional space with respect to the region by the use of a series of data determining the region (the relative positional data including data indicating whether the point is inside or outside the region, the distance from the point to the boundary of the region, etc.), thereby identifying the region with the procedure, and thus unitarily determining the region; generating a relative expression procedure for a new region from the relative expression procedure(s) of one or more regions given the procedures, the relative expression procedure for the new region being obtained by configurationally processing and editing the one or more relatively expressed regions, thereby relatively expressing the new region; and expressing configurational characteristics of each relatively expressed region itself by the use of the relative expression procedure of the region. Thus, the processing of patterns in an n-dimenaional space can be unitarily effected on the basis of the one and only concept, that is, the relative expression procedures, without deponding upon the configuration of each particular region as being an object of processing so that the pattern processing method itself is simplified.
摘要翻译：提供了一种图案处理方法，其针对n维空间中的区域执行以下步骤：提供用于生成关于n维空间中的任何希望点的相对位置数据的过程（相对表达过程）通过使用确定该区域的一系列数据（相对位置数据包括指示该区域是在区域内还是在该区域内的数据，从点到该区域的边界的距离等）的区域，从而识别区域具有程序，从而统一确定区域; 根据给定过程的一个或多个区域的相对表达过程，针对新区域的相对表达过程，通过结构化处理和编辑一个或多个相对表达的区域获得的新区域的相对表达过程，由此相对表达新区; 并通过使用该区域的相对表达程序来表达每个相对表达的区域本身的构型特征。因此，可以基于唯一的概念，即相对表达过程，在不将每个特定区域的配置视为处理对象的情况的基础上，一体地实现在n维空间中的图案的处理。模式处理方法本身就简化了。

摘要： A three-dimensional shape as a synthesis of three-dimensional geometry entities is controlled and displayed. The geometry entities are controlled in accordance with information defining the geometry entities, and layout information arranged in a three-dimensional space. An interface between graphic display apparatus using this graphic display method and an application system is practiced in that the transfer of the information on the geometry entities is carried out. The three-dimensional shape is divided into its geometry entities, and the display of an object having a three-dimensional shape is done as a synthesis of the geometry entities, the transfer of shape data being done separately for each geometry entity.

摘要： A graphic display processing system is disclosed, in which a two-dimensional pattern or an image of a three-dimensional pattern can be displayed on the display screen of a display device, and moreover it can be rapidly judged whether or not each graphic data on a display list formed in a graphic data buffer corresponds to a pattern in a pattern pick region (namely, pick aperture) set on the display screen. In more detail, display color data in the pick aperture is first read out of a frame memory for storing image data. In a case where an image of a three-dimensional pattern is displayed, depth values in the pick aperture are read out of a Z-buffer for storing depth values with respect to a displayed pattern. Next, the read-out display color data is compared with display color commands on the display list, or the read-out depth values are compared with depth values obtained from geometrical form commands on the display list, to check whether or not each graphic data on the display list indicates the same display color or depth value as that of a pattern to be picked, thereby selecting only graphic data which is judged to indicate the same display color or depth value as that of the to-be-picked pattern. Then, it is checked whether or not the selected graphic data indicates a pattern intersecting with the pick aperture. Thus, desired graphic data can be rapidly picked out of the display list.
摘要翻译：公开了一种图形显示处理系统，其中可以在显示装置的显示屏上显示三维图案的二维图案或图像，并且还可以快速判断每个图形数据是否在形成在图形数据缓冲器中的显示列表对应于设置在显示屏幕上的图案拾取区域（即拾取孔径）中的图案。更详细地，首先从用于存储图像数据的帧存储器读出拾取孔中的显示颜色数据。在显示三维图案的图像的情况下，从用于存储相对于显示图案的深度值的Z缓冲器中读出拾取孔径中的深度值。接下来，将读出的显示颜色数据与显示列表上的显示颜色命令进行比较，或者将读出的深度值与从显示列表上的几何形式命令获得的深度值进行比较，以检查每个图形数据在显示列表中指示与要拾取的图案相同的显示颜色或深度值，从而仅选择被判断为指示与所选择的图案相同的显示颜色或深度值的图形数据。然后，检查所选择的图形数据是否指示与拾取孔相交的图案。因此，可以从显示列表中快速地选出期望的图形数据。
