摘要： PROBLEM TO BE SOLVED: To reduce weight by connecting the ends of adjoining diagonal members through universal joints, embedding these universal joints in prestressed concrete and connecting the diagonal members and upper chords or lower chords. SOLUTION: An upper chord 11 and a lower chord 12 are composed of prestressed concrete, and a diagonal member 13 is made up of steel. The ends of adjoining diagonal members 13 are connected through universal joints 14, and connected to the upper chord 11 or the lower chord 12 by embedding the universal joints 14 in prestressed concrete. Such structure helps the diagonal members 13 to be joined to the upper chords 11 or lower chords 12 strongly. In addition, as the universal joints 14 are merely embedded in the upper chords or the lower chords 12 together with the ends of the diagonal members 13, a panel-point structure that connects the diagonal members 13 and the upper chords 11 or the lower chords 12 never get larger. Furthermore, the diagonal members are made of steel. Therefore, it is possible to reduce the weight.

摘要： PURPOSE: To discriminate quickly whether or not a building going to be built is within a view from important visual points in an inside of a temple or the like requiring preservation or protection of borrowing landscope even when a construction plan of the building is set forth around the temple or the like by obtaining a clearance of each calculating point and generating a clearance map based on the obtained clearance information. CONSTITUTION: A clearance map generation program 11 set in a computer system 10 is started. Then desired view points in an inside of a temple being an object of evaluation are pointed out by using a key board 13 or the like. The altitude of four points in the vicinity of an arranged calculation point is read out of a 2nd DEM file stored in a hard disk 14 when arranged calculation points are in the inside of or adjacent the temple or the like for the evaluation or read out of a 1st DEM file in other cases, and the altitude of the calculation point is obtained through a weighting interpolation calculation depending on distance. The elevation angle and the clearance from the view point are calculated by using the obtained altitude to generate a clearance map.

摘要： PURPOSE: To obtain a highly accurate three-dimensional data in no contact with a solid-shaped object by a method wherein a solid object is photographed from a free angle to determine slice points containing feature points of a solid shape and a slice data is measured to present the shape of the solid object. CONSTITUTION: Dimensional elevation models(DEM) are generated from a stereoscopic photograph, for example, using an analytic graphic convertor. A contour line is determined from the DEMs to be converted into a graphic of contour. The contour line shows the contour of a solid object at an equal elevation and in a contour measuring method, several different elevations are selected at an equal interval to determine the contour lines. In the contour graphic of a solid object, equal elevation lines 1A-5A corresponding to contour lines 1-5 are made equal in interval. Thus, a three-dimensional stereoscopic model is reproduced. In the slice measuring method, a measurement is made in slices with a solid observation using a stereoscopic photograph of a solid taken from all directions to determine the shape of cuts sliced three-dimensionally.

摘要： PURPOSE:To make it possible to extremely easily and inexpensively execute two-dimensional mapping and photograph map formation. CONSTITUTION:The method for two-dimensionally forming the digital mosaic photograph maps comprises utilizing geometrical conversion processing of digital data using affine conversion, etc., in order to strictly comply airial photographs with reference maps. Only the inside of respective batches are partly subjected to distortion removal and these parts are continuously connected, by which the geometrical correction over the entire part is executed. Partial geometrical correction is repeated by combining the image processing technique meeting the conversion equations and the technique of making polygon decision, by which the images having the geometrical compliance overall are obtd.

摘要： PURPOSE:To facilitate the construction of a 3-dimensional model by reading the 2-dimensional image of a drawn shaped body out of a perspective view and applying the arithmetical interpolation to the 3-dimensional coordinates of the shape matter after extraction of disappeared points which is not shown on a plan and the visual point and the symmetrical faces of the shape matter set at drawing of the perspective view. CONSTITUTION:A scanner 1 reads the 2-dimensional image of a laterally symmetrical shaped body drawn by a 2-spot or 3-spot perspective viewing method out of a perspective view. Then disappeared points which are not shown in the perspective view and the visual point and the symmetrical faces of the shaped body set at drawing of the perspective view are extracted out of the 2-dimensional image. Then the 3-dimensional coordinates of the shaped body are computed by an arithmetic processor 3 for interpolation. Thus it is not required to produce a model with trees or clay as conventional for production of a 3-sided view. Then a 3-dimensional model is easily constructed.
