To enable those skilled in the art to understand the present invention in more detail, the present invention is retouched in detail below in conjunction with accompanying drawing
State.
The concept of three-dimensional map is introduced first.
The three-dimensional map be based on electronic three-dimensional map database, according to a certain percentage to real world or its
In a part a many aspects three-dimensional, abstract description.In general, three-dimensional map can include ground and aerial
Two parts, wherein, the part on ground can typically include specific model, and aerial part will not typically include specific mould
Type.Say so and, when needing by coordinate determine instruction to obtain coordinate points, especially by mouse click on really
When position fixing point, the part for facing ground is selected easily by the click of mouse, and aerial part is not easy to lead to
The click for crossing mouse carries out the technical problem of selection.
As described in Figure 1, Fig. 1 is a kind of determination method of coordinate in three-dimensional map in one embodiment of the invention, wherein, it is described
Method includes：
Step 110：Obtain a coordinate determine instruction；

The instruction that the coordinate points of mark cursor position are determined.Wherein, step 110 is a kind of three-dimensional in the embodiment of the present invention in order to start
The determination of coordinate in map.
Step 120：According to the coordinate determine instruction, a scene collector is transferred；
Specifically, step 120 is to transfer a scene collector according to coordinate determine instruction, and its Scene collection equipment has
The coordinate value of itself, also it is achieved that the seat that scene collector position is converted to by the scene collector coordinate value of itself
Scale value.The coordinate determination mode commonly used for three-dimensional map, i.e., for cursor of mouse acquisition modes, the present invention can pass through mouse
Drag scene collector, and then obtain the accurate coordinates value of specified location, solve can not skyborne point coordinate identification
The problem of.Specifically, scene collector includes reference axis base class parameter, and the reference axis base class parameter is mainly used in gathering scene
The coordinate value parameter information of collector, wherein, reference axis base class parameter mainly includes two classes, and one is position shifting axle；Two be angle
Degree adjustment axle.Specifically, position shifting axle mainly mainly passes through angle by position shifting axle event handling class, angular adjustment axle
Degree adjusts event handling class to monitor all kinds of events of scene collector respectively.
Step 130：Obtain the first coordinate position in the three-dimensional map of the scene collector；
Specifically, step 130 obtains first coordinate position of the scene collector in the three-dimensional map, that is, obtains
The scene collector coordinate position of itself was obtained, the scene collector belongs to a real model for three-dimensional map,
Also just it is provided with the coordinate position of itself.So for three-dimensional map, the coordinate bit of model existing for a reality is obtained
Put the normal attribute for belonging to three-dimensional map.
Step 140：First coordinate position is defined as to the first output content of the coordinate determine instruction；
Specifically, the first coordinate position of the scene collector is defined as the defeated of coordinate determine instruction by step 140
Go out content, i.e., the present invention passes through the simple, fast and efficient coordinate determine instruction that realizes of the own coordinate value of scene collector
Export content.
Further, coordinate can be carried out to position different in three-dimensional map to realize by mobile context collector
It is determined that.One embodiment of the invention additionally provides following method：

Coordinate position is different from second coordinate position；
Specifically, scene collector is moved to three-dimensional map by step 150 by the first coordinate position in three-dimensional map
In the second coordinate position, wherein, the first coordinate position is different from the second coordinate position；
Step 151：Second coordinate position is defined as to the second output content of the coordinate determine instruction.
Specifically, second coordinate position of the scene collector in three-dimensional map is obtained in step 151, second seat
Scale value is still itself coordinate value of the scene collector in three-dimensional map, and the step is also achieved that to be gathered according to mobile context
The position of device reaches the technique effect for determining the coordinate value in multiple three-dimensional maps.
As mentioned above, three-dimensional map generally comprises ground and aerial two parts, and wherein Aerial parts are not due to having
Concrete model, it is difficult to determine the coordinate value of Aerial parts, that is to say, that because Aerial parts and above ground portion have difference
Attribute, the embodiments of the invention provide checking whether to belong to Aerial parts first, it is then determined that whether transferring scene collector
Process, as described below：
Step 160：Judge the object that the coordinate determine instruction is directed in the three-dimensional map；
Step 161：When the object being directed to is located at the Aerial parts in the three-dimensional map, transfers the scene and adopt
Storage, wherein, the three-dimensional map includes Aerial parts and above ground portion.
Step 162：When the object being directed to is located at the above ground portion in the three-dimensional map, the floor portion is obtained
The 3rd coordinate position divided, and export content using the 3rd coordinate position as the 3rd of the coordinate determine instruction.
Specifically, the object that the present embodiment is directed to by determining coordinate determine instruction first, whether it is specifically not
The Aerial parts of coordinate position can be effectively determined, in this way, then transfer scene collector；If not, directly it is directed to by transferring
Object in the coordinate position of threedimensional model realize the technique effect of effective output content of coordinate determine instruction.
Further, as mentioned above, scene collector both includes position shifting axle, and it is by position shifting axle come real
Move to determine the coordinate value of diverse location the position of live scape collector；Also include angular adjustment axle, it is certain by rotating
Angle so that realize the angle change of the model behind scene collector, and then show for the various dimensions of model.Tool
For body, methods described also includes：
Step 170：Determine the 4-coordinate position of the scene collector；
Step 171：The threedimensional model according to corresponding to the 4-coordinate position determines the scene collector；
Step 172：Rotate the angular adjustment axle；
Step 173：The threedimensional model is rotated according to the angular adjustment axle.
Specifically, then above-mentioned steps pass through the position of scene collector by determining scene collector position first
Put to determine the threedimensional model in three-dimensional map corresponding to scene collector, then by adjusting the angle adjustment of scene collector
The angle of axle, you can to rotate the threedimensional model, reach and skill that threedimensional model various dimensions show is realized by scene collector
