Detailed description of the invention
Fig. 1 is schematic diagram of the invention.
Specific embodiment
Referring to attached drawing, specific description is done to embodiments of the present invention.
The present invention provides it is a kind of it is abstract with tool as the three-dimensional data of combination gets system ready, as shown in Figure 1, including that coordinate is raw
At module, threedimensional model generation module, database module and point location module, Coordinate generation module for generating three according to the map
Coordinate system is tieed up, wherein map can be city map, and point location module is connect with Coordinate generation module, and point location module is used for
Coordinate is got in determination ready in the three-dimensional system of coordinate generated according to the map, and threedimensional model generation module is connect with database module, three-dimensional
For model generation module for generating threedimensional model, wherein threedimensional model includes various buildings, facility or personage, is specifically wrapped
House, trees, camera, street lamp, vehicle, pedestrian etc. have been included, and has been stored into database module convenient for calling, threedimensional model is raw
Threedimensional model can be placed in getting ready on coordinate in three-dimensional system of coordinate at module, therefore get coordinate ready no longer only by abstract
Symbol indicates, can more intuitively indicate to get coordinate ready by threedimensional model.
It preferably, further include the status information for getting coordinate ready in database module, above system further includes display module, is shown
Show that module can show status information getting ready by the corresponding threedimensional model of coordinate, such as get coordinate pair ready and answer building, beats
The status information of point coordinate includes address, title, height, repair and maintenance state of building etc..
Preferably, threedimensional model generation module can be generated the threedimensional model of the same race comprising multiple states, for example, street lamp and
Road camera, the street lamp and road camera of multiple states refer to the road in normal operating conditions and abnormal operating state
Lamp or camera, and the threedimensional model of different conditions has apparent labeled difference, such as color and shape etc., therefore three-dimensional
The threedimensional model that model generation module generates can correspond to a variety of different conditions.It include multiple subdata bases in database module
