This is not construed as limiting.
Step 102, according to described multiple images, generates image data；
In the embodiment of the present application, the image data may refer to be synthesized the single image for obtaining by multiple images.Example
Such as, for multiple images for gathering in a step 101, after aerial triangulation technical finesse, can be by above-mentioned multiple figures
As synthesizing a digital orthoimage.Typically for the image data that 150 left images synthesis are obtained, its size of data
About 1G.
Aerial triangulation technology is in stereophotogrammetric survey, according to a small amount of field control point, to be controlled indoors
Point encryption, tries to achieve the elevation of pass point and the measuring method of plan-position.Digital orthoimage (the Digital
Orthophoto Map) it is that one by one pixel is carried out Jing using digitized airphoto of the digital elevation model to scan process
Height displacement corrects, then by image mosaic, according to figure amplitude range the image data of generation is cut out.
Generally, image data includes corresponding coordinate information, and the coordinate information is the coordinate system specified at certain
The information of the coordinate under system, such as wgs-84 coordinate systems (World Geodetic System-1984Coordinate
System).The wgs-84 coordinate systems are a kind of geocentric coordinate systems widely used in the world, and its zero is earth matter
The heart, the Z axis of its earth's core rectangular coordinate system in space point to BIH (Bureau International de I ' Heure, international time
Service organization) 1984.0 agreement earth pole (CTP) directions for defining, zero meridian plane of X-axis sensing BIH 1984.0 and CTP equator
Intersection point, Y-axis and Z axis, X-axis be vertically formed right-handed coordinate system, and wgs-84 coordinate systems are referred to as World Geodesic Coordinate System 1984
System.
But, may need image data and other data in actual applications, such as vector data is overlapped aobvious
Show, and other data are possibly using the data of other coordinate system, such as UTM systems (Universal transverse
Mercartor grid system, Universal Trans Meridian grid system).The UTM systems are a kind of plane rectangular coordinates, this

Include following steps：
The coordinate information of the image data is converted, the image data with specified coordinate information is obtained.
In the embodiment of the present application, it is preferably aobvious in order to reach when display is overlapped to image data and other data
Show effect, can be by the data processing under different coordinate systems under the same coordinate system.For example, by under wgs-84 coordinate systems
Image data, after treatment, output obtain UTM systems image data.Certainly, those skilled in the art can be according to reality
Border is it needs to be determined that the specific coordinate system for needing to change, for example, by the image data of UTM systems wgs-84 coordinate systems are transformed to
Under image data or the data under other coordinate systems, the embodiment of the present application is not construed as limiting to this.
Step 103, extracts the target image data with given resolution from the image data；
Generally, the usual data volume of image data is than larger, especially high resolution image, and individual size of data can reach
Several G, this data volume is close to customary personal computer's internal memory, it is impossible to directly display.Therefore, in the embodiment of the present application
In, after image data is obtained, can be extracted from the image data with specified resolution according to actual application needs
The target image data of rate.
In implementing, resampling can be carried out to the image data, so as to obtain the mesh with given resolution
Mark image data.
The resampling (resampling) is exactly the mistake for going out another kind of picture dot information according to the message interpolation of a class picture dot
Journey, specifically, resampling is a kind of process that low resolution image is extracted from high resolution image.
For example, for resolution is the raw video data of 10000*10000, resampling is being carried out to the initial data
Afterwards, the data that resolution is 5000*5000 are obtained, it is believed that the latter is the former thumbnail, loses parts of images details,
But data volume has been reduced to original 1/4, in the same manner, if generating data of the resolution for 100*100 by resampling, then number
The 1/10000 of raw video data can be just reduced to according to amount, for the image data of 1G sizes, its data volume will be simplified
To about 100kb (kilobytes).
Therefore, in actual applications, when resampling is carried out to raw video data, many parts of different resolutions can be generated
Target image data, for example, can be based on resolution for 10000*10000 raw video data, generate resolution difference
For the target image data of 5000*5000,2000*2000,1000*1000,500*500,200*200 or 100*100, supply not
Same display yardstick is used.
Step 104, for the target image data, generates tile images, and the tile images have corresponding image
Information；
Tile (Tile), refers to a range of map according to certain size and form, by level of zoom or
Scale, is cut into the square grid picture of some row and columns, and the square grid picture after section is becomes tile.
In implementing, after the target image data for generating given resolution, the target shadow can be first determined
It is multiple tile images by target image data cutting then from the beginning of the zero as the zero of data.
For example, can be with the lower left corner (B0, L0) of selected target image data for zero, then according to certain pixel
Size carries out cutting to the target image data, so as to obtain multiple tile images.Certainly, those skilled in the art go back
Other positions can be selected as the zero of target image data, for example, selection target image data according to practical situation
The upper left corner, the upper right corner, the lower right corner or central point as zero, the embodiment of the present application is not construed as limiting to this.
After being multiple tile images by the cutting of target image data, it may be determined that go out the corresponding image of every tile images
Information, such as the corresponding pixel coordinate of described tile images, line number, column number, picture level, picture format, and, pixel point
Resolution etc..
When many parts of target image data are generated when resampling is carried out to original image data, the picture level is then
The corresponding level of the target image data, the pixel resolution is then the corresponding resolution of target image data.For example, exist
Resampling is carried out for the raw video data of 10000*10000 to resolution, resolution is generated and is respectively 5000*5000,2000*
2000th, 1000*1000,500*500,200*200 and 100*100 are corresponding to resolution after totally six parts of target image data
The picture level of the target image data of 100*100 is 6.
Further, cutting is being carried out to target image data according to certain Pixel Dimensions size, is obtaining multiple tiles
Can be in a certain order that every tile images are numbered after image so that every tile images have a row to compile
Number and column number, at the same time it can also the Pixel Dimensions size adopted according to the pixel size of target image data and cutting,
The corresponding pixel coordinate of each tile images is calculated respectively.
Step 105, stores the tile images and its corresponding image information.
In implementing, the tile images and its corresponding image information write file that can be obtained cutting are deposited
Storage.
For example, the image information of storage can specifically include following content：
Rank：5 (representing the level that current tile image is located)；
Picture line number：100 (representing that current level has 100 row tiles)；
Picture columns：200 (representing that current level has 200 row tiles)；
Picture format：Png (tile images storage format)；
Pixel resolution：0.01 (represents the size on the spot that pixel wide is represented, dimensional units on the spot in present exemplary
For degree, therefore, pixel wide represents 0.01 degree on the spot of length)；
Scale：0.01 (i.e. 1:0.01, that is, it is 1 to scheme upper size with the ratio of size on the spot:0.01.
Further, when storing to tile images, the entirety corresponding to current impact data can also be included
Data message, for example：
Image data number of levels：20 (indicating 20 layers of tile)；
Scope of data：(23 ° 58 ' 3 ", and 113 ° 30 ' 50 ") (24 ° 58 ' 3 ", 114 ° 30 ' 50 ")；
Origin：23 ° 58 ' 3 ", 113 ° 30 ' 50 "；
Tile is high：256 (representing the pixels tall of tile images)；
Tile width：256 (representing the pixel wide of tile images)；
