ジャーナル フリーWhen all the edges of a solid are congruent, the figure is known as a regular polyhedron. This paper describes on relation to a projective method using several values obtained geometrically in case of five regular polyhedrons. It is also shown that the properties are estimated by the comparison between a length of edge and radii of inscribed or circumscribed circles on base polygon and other polygon at plan, whose required values may be measured.
Hence, each height of the vertexes for elevationcan be drawn without rotating of polygon as usual.The tables show the numerical values together withthe drawings displayed by using the values, i.e.the sphere of inscribed and circumscribed in aregular polyhedron and so on.抄録全体を表示PDF形式でダウンロード (424K) -

ジャーナル フリーWhen the picture plane is not perpendicular to the ground plane, there exist three vanishing points. In this case, we studied on a method to draw a perspective by using axsometric scale.
For a straight line, lying on the ground plane and parallel to x or y axis, axsometric scale is intersecting points of total perspect of this straight line and a group of straight lines.
They are total perspects of parallels lying on the ground plane. Inclination angles of parallels to both axes are 45° and their intervals are constant.
For a straight line, parallel to z axis, axsometric scale is intersecting points of total perspect of this straight line and a group of straight lines. They are total perspects of parallels lying on a plane on which this straight line lies. Parallels are horizontal and their intervals are constant.抄録全体を表示PDF形式でダウンロード (570K) -

ジャーナル フリーIt is popular to adopt a binocular stereographic technique for obtaining spacial information of objects in an outside scene. This technique is based on a binocular parallex of two pictures which are taken by separated cameras focusing the same object.
In this paper we propose a system to extract spacial information automatically using this technique. The pictures are digitized by our drum-scanner and the data are punched on paper tapes so as to feed an image processor. The processor extracts feature points on each scanning line from image data, and detects the deviations of positions for all features appeared in both pictures. The coodinates of feature points in the 3-dimensional space can be calculated numerically from values of these deviations.
Performing a proper coodinate transformation to these data, the processor composes image data such as a ground plane, a front view and a perspective. Then outputs these images using a dot-printer.
Therefore the image processor system proposed can be put into practice.抄録全体を表示PDF形式でダウンロード (3983K) -
