Application scenarios of the present invention is below described.At first, on existing city street diagram data, according to the road conditions of reality, use 3D software to draw three-dimensional plot, the three-dimensional plot of neighboring buildings and the three-dimensional plot of road of poi (point of interest).In figure, with the ad-hoc location of tapered mark point of interest, the position on doorway for example.Be specially: by city street diagram data, use 3D software to draw the planar graph of poi object, neighboring buildings and road, utilize 3Dmax extrusion tool input high level data, lift key element such as building, at ad-hoc location (for example, homeposition, in-position, position, gate) etc. position, actual point position with the green tapered mark that carries out, guarantee that simultaneously the data of homeposition, in-position, big doors position are consistent with collection quantity.Simultaneously, make enclosure wall and fix the scope of making object.Then, check the coordinate of unique pixel of each tapered bottom, measure the figure internal coordinate and import in the corresponding association list that it is related that linked list and database carry out, so that the follow-up highlighted specific location of coordinate according to ad-hoc location is tapered.When the client when using the navigating instrument retrieval, can be by the highlighted tapered exact position of clearly understanding homeposition and in-position.For example, when customer selecting is gone to the airport, can see airport whole structure and road relation on every side, in 3D figure, use the in-position on tapered pictorial symbolization airport, thereby can judge the position of arrival intuitively simultaneously.Perhaps, when the client imports the building titles such as park that will go, by calling the information in the internal database, in navigating instrument, show the 3D figure in park.When selecting to remove the park east gate, can call the figure internal coordinate in the contingency table of database, tapered by the coupling of the coordinate position in the contingency table, in the 3D figure, show the physical location of the park east gate that the client will reach.
The present invention has following beneficial effect:
(1) arrive at the airport when the client wants to inquire about, during the concrete position on the doorway of main facilities such as train, the position on overall appearance that can be by the navigating instrument query facilities and the doorway of arrival.
(2) the present invention uses point of interest and true ground and the floor height of scene building on every side in advance, makes the 3D effect figure, to guarantee consistance on-the-spot and figure.
(3) setting out and arrive the particular location place on doorway by the clear expression object of tapered icon.For the client provides the overall scenario synoptic diagram of point of interest building, thus the position that the user can clear judgement sets out, arrives.
(4) provide the point of interest that will go pattern and with the relation of neighboring buildings, road.
Among the present invention, point of interest can be buildings such as airport, train, and reference position and destination locations can be the doorway.
The above is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
