Abstract
The invention discloses a method for exhibiting spatial field intensity results in a three-dimensional mode. Through five steps of manufacturing DTM, manufacturing a three-dimensional real scene, gridding the three-dimensional scene and matching coordinates, judging whether a building is at the position of the coordinates and exhibiting the three-dimensional field intensity results, the spatial field intensity results are exhibited in the three-dimensional mode. The method for exhibiting the spatial field intensity results in the three-dimensional mode realizes the effect that a field intensity result graph is attached to building drawing according to the intelligent exhibited spatial field intensity results of the building because the judgment whether the building is on the DTM is added.
Description
Technical field
The present invention relates to spacial flex field intensity result's method, particularly a kind of under three dimensional pattern spacial flex field intensity result's method.
Background technology
At present, the field intensity result is employed under the two-dimensional model to show in systems such as electromagnetic compatibility, frequency planning.This exhibition method can not be expressed the influence of three-dimensional objects such as house in the real space, trees and high mountain to the space field intensity well, and concerning unprofessional user, it is uninteresting that this result shows, does not have expected effect in the brain of back and just look at.Though trial digital terrain model (DTM) has been arranged field intensity is showed that figure imports in the three-dimension GIS scene with picture format as a result; But this field intensity shows that the figure layer depends on DTM as a result; But for the buildings on the DTM; Field intensity shows that figure only is presented at the buildings bottom surface as a result, actual result that can accurately the expression of space field intensity.
Summary of the invention
The present invention a kind of under three dimensional pattern spacial flex field intensity result's method aim to provide a kind of displaying that makes space field intensity result depend on landform and on the method for object; Make the space field intensity accurate expression of space field intensity actual distribution situation of exploded view layer as a result, give the user to show the result intuitively.Further programme provides true, credible, the space field intensity is showed the result intuitively for the related work personnel design.
The present invention a kind of under three dimensional pattern the technical scheme of spacial flex field intensity result's method following:
The first step: make DTM, set up three-dimension GIS basis-DTM based on actual conditions, based on the three-dimensional geographic information display platform; Through integrating sight spot aviation or satellite photo, stack digital elevation model (DEM) data, synthetic dimensional topography with true coordinate and fluctuating; Then through loading data such as threedimensional model, label character, vector data; Make up three-dimensional scenic, be concerned about regional landform, landforms, atural object, can use careful, the real three-dimensional scenic of high-resolution data construct for emphasis;
Second step: make three-dimensional real scene,, select suitable propagation model according to the actual landform situation, the computer memory field intensity, span field strength distribution result data then, imports to described space field intensity distributed data result in the three-dimensional real scene;
The 3rd step: with go forward side by side row-coordinate coupling of three-dimensional scenic gridding; DTM figure is infinitely cut apart; Granulation is the unlimited a plurality of points based on coordinate; Make DTM figure and TIF figure with based on the point of coordinate as the matched and searched parameter, to the color attribute assignment of same coordinate points, can accurately depict the true distribution results of the space field intensity of each point;
The 4th step: judge whether buildings is arranged on the coordinate position;
The 5th step: show three-dimensional field intensity result, if on the coordinate position building is arranged, then read described building height h, the last height of DTM is made as described space field intensity color for the color attribute of h position; If there is not building on the coordinate position, then the color attribute of the last relevant position of DTM is made as described space field intensity color.
The present invention a kind of under three dimensional pattern the beneficial effect of spacial flex field intensity result's method be: described under three dimensional pattern spacial flex field intensity result's method added the judgement whether building is arranged on the DTM; According to buildings intelligence spacial flex field intensity result, realized field intensity as a result figure depend on the effect of buildings drawing.
Description of drawings
Fig. 1 be the present invention a kind of under three dimensional pattern the process flow diagram of spacial flex field intensity result's method.
Embodiment
Embodiment one:
At first, confirm zoning A.
The first step: make the DTM of regional A, set up three-dimension GIS basis-DTM, based on the three-dimensional geographic information display platform based on the actual conditions of regional A; Through integrating sight spot aviation or satellite photo, dem data, synthetic dimensional topography with true coordinate and fluctuating; Then through loading data such as threedimensional model, label character, vector data; Make up regional A three-dimensional scenic, be concerned about regional landform, landforms, atural object, can use careful, the real three-dimensional scenic of high-resolution data construct for emphasis;
Second step: the three-dimensional real scene of making regional A; Actual landform situation based on regional A; Select suitable propagation model, the space field intensity of zoning A generates the space field intensity distribution results data of regional A; Then, the space field intensity distributed data result with described regional A imports in the three-dimensional real scene of regional A;
The 3rd step: with go forward side by side row-coordinate coupling of the three-dimensional scenic gridding of regional A; The DTM figure of regional A is infinitely cut apart; Granulation is the unlimited a plurality of points based on coordinate; Make regional A DTM figure and regional A TIF figure with based on the point of coordinate as the matched and searched parameter, to the color attribute assignment of same coordinate points, can accurately depict the true distribution results of the space field intensity of each point in the regional A;
The 4th step: judge on the regional A internal coordinate position whether buildings is arranged;
The 5th step: show three-dimensional field intensity result, as if on the coordinate B position selected in regional A building being arranged, then read the building height h on the described coordinate B position, then DTM goes up height and is made as space field intensity color for the color attribute of h position; If there is not building on the regional A internal coordinate C position, then the color attribute of the last relevant position of DTM is made as space field intensity color.
