Particularly, technical scheme of the present invention is mainly divided into three parts: 1, selected navigation area, sets up coordinate system; 2, changes in coordinates is carried out to the longitude and latitude in navigation area; 3, the foundation of physical location under logarithmic coordinate system.
1, selected navigation area, the foundation of coordinate system.Mainly comprise the following steps:
1) region of selected navigation, can be an area or country;
2) take latitude as transverse axis, longitude is the longitudinal axis, and selected zone is outer or a point (access areas edge) on edge sets up latitude and longitude coordinates system as true origin; Certainly, can take also longitude as transverse axis, latitude be that the longitudinal axis sets up coordinate system.
3) point of coordinate system is designated as: w=(x

2, changes in coordinates is carried out to the longitude and latitude in navigation area, be converted to logarithmic coordinate system by latitude and longitude coordinates system.
1) latitude and longitude coordinates system difference:
Coordinate system difference is that latitude and longitude coordinates system deducted true origin a little, and true origin is normalized to (0,0), and differentiated coordinate system is as follows:
W＝(x
1-x
0,y

3, the foundation of physical location under logarithmic coordinate system.
Logarithmic coordinate conversion is linear transformation, and the point of latitude and longitude coordinates is one to one to the point of new coordinate system.So by the coordinate one_to_one corresponding after the actual physical location corresponding to longitude and latitude and change, its corresponding relation as shown in Figure 3.
Below in conjunction with specific embodiment, technical scheme of the present invention is described in detail.
1, the choosing of region.
Longitude range shared by Shenzhen is: 113.7667 degree to 114.6167 degree, latitude variation range is: 22.45 degree to 22.8667 degree.Some the longitude and latitude points choosing Shenzhen are as follows: (22.4501,113.7668), (22.4510,113.7677), (22.4600,113.7767) and (22.5500,113.8667).
2, coordinate transform.
2.1, (22.45 are chosen, 113.7667) as the initial point of new changes in coordinates, the result obtained after above-mentioned four points deduct initial point is as follows: (0.0001,0.0001), (0.0010,0.0010), (0.0100,0.0100), (0.1000,0.1000).
2.2, by above-mentioned change formula, k is chosen
1and k
2be 1, α, β be 10, then the point after coordinate transform is: (-4 ,-4), (-3 ,-3), (-2 ,-2), (-1 ,-1).
2.3, select translation coefficient C to be 4, then four points become (0,0), (1,1), (2,2), (3,3) successively, and negative coordinate figure is converted to positive number coordinate figure.
3, the foundation of physical location under logarithmic coordinate system.
By longitude and latitude (22.4501,113.7668), (22.4510,113.7677), (22.4600,113.7767), (22.5500,113.8667) position corresponding to respectively with (0,0), (1,1), (2,2), (3,3) are mapped.
Although the point chosen in above-described embodiment is the convenient particular point calculated, by reasonably choosing k
1, k
2and α, β, then latitude and longitude coordinates can be converted to rounded coordinate in conjunction with the precision (relevant with the radix point given up after conversion) of location.
Technique scheme of the present invention has following technique effect:
1) floating-point operation can be converted into integer arithmetic, decrease the data processing amount of processor.Such as carrying out data processing to (0,0) is easy to many than process (22.4501,113.7668).
2) delete the part of redundancy in latitude and longitude coordinates information, reduce the task amount of data transmission and memory space.Such as longitude and latitude (22.4501,113.7668) in, the information of integral part is redundancy completely for one's respective area, the coordinate transform of this programme can effectively remove this redundant information, reduce data and store the difficulty with process, store obviously and transmission (0,0) be easy to many than (22.4501,113.7668).
3) the present invention is owing to have employed logarithm operation, make value comparatively small data be amplified on range, very large data are reduced, and the range of data is optimized, simplifies the difficulty of subsequent control, also improve the precision of follow-up data process.
The application scenarios of technique scheme of the present invention is more, according to such scheme, original latitude and longitude coordinates system is converted to rounded coordinate system as prior, follow-uply to locate accordingly, process etc. of navigating; Or Real-time Obtaining, to the locator data of target object, then processes locator data according to such scheme, to obtain the rounded coordinate of target object, facilitate computing.
More than be described with reference to the accompanying drawings technical scheme of the present invention, consider that current locator data is normally carried out recording with floating number and transmits, and the twice of figure place shared by floating-point numerical representation normally integer, add the difficulty of storage, too increase the data volume of transmission; From the angle of data processing, processor is to be processed is floating data, and the intractability of floating data will much larger than the intractability of integer, so directly position with longitude and latitude data the difficulty adding data processing.Therefore, the present invention proposes a kind of processing scheme of new locator data, the redundancy section in locator data can be deleted, reduce the process to locator data and storage difficulty, decrease the data processing amount of processor simultaneously, reduce the processing load of processor.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
