Concrete meaning in invention.
Below with reference to Fig. 1 description, navigating for embodiment flies the loading method of striograph according to a first aspect of the present invention.
As shown in Figure 1, according to an embodiment of the present invention navigate flies the loading method of striograph, comprising the following steps:
Step S1, at county level, township level, at village level, group grade boat are flown into striograph respectively according to different scale compressions at correspondence
Thumbnail;
Step S2, it extracts to navigate and flies the four angular coordinate system of striograph, production " navigates and flies image four angular coordinate attribute list ";
Step S3, when need to load at county level, township level, it is at village level, group grade boat fly striograph when, then load at county level, township respectively
Grade, at village level, group grade boat fly the corresponding thumbnail of striograph, when the boat that needs load is less than group grade region flies striograph, then
Execute step S4;
Step S4, extraction needs to be loaded navigate to fly the coordinate range of striograph, and finds matching " the winged striograph of boat
Corresponding " coordinate " value in four angular coordinate attribute list ", corresponding navigate of load " coordinate " value fly striograph.
Specifically, firstly, it is exactly the base map use as plot that platform load boat, which flies striograph, and there is no other works
With, it is possible to the thumbnail for making respective range promotes speed by reducing the data volume of load;Secondly, GIS software
Screening and loading method cannot fully meet the demand of platform, need to optimize in advance search function, and shielding is not required to boat to be loaded
Fly striograph, to promote the speed of platform load.It needs to show to navigate according to platform and flies the size of striograph range, fly image for navigating
Figure is compressed into thumbnail according to 4 grades of other, township at county level, village, group administrative grades merging, further, extracts winged striograph quadrangle of navigating
Coordinate is fabricated to " navigate and fly image four angular coordinate attribute list ".When platform needs range to be shown to reach county, township, village, group region
When, its corresponding thumbnail is just called directly, speed is fast and will not influence display quality;When platform needs range to be shown small
When group grade region, first extracting needs coordinate range to be loaded, then compares and " sit in " navigate and fly striograph four angular coordinate attribute list "
Mark " value, then the corresponding winged striograph that navigates of " coordinate " value is somebody's turn to do in load, and the loading method loading velocity which flies striograph is fast, matter
It measures.
In other words, as shown in Figures 2 to 7, obtained firstly, flying striograph according to different scale compression boats according to administrative region
Fly at county level navigate of image thumbnail 10, township level at county level boat of the Fig. 2 into Fig. 5 and flies image thumbnail 20, the at village level winged image breviary that navigates
Figure 30 and group grade navigate and fly image thumbnail 40, then, fly striograph four angular coordinate system 50 as shown in fig. 6, extracting and navigating, are fabricated to figure
" navigate and fly image four angular coordinate attribute list " in 7.
The scale bar of some specific embodiments according to the present invention, the winged striograph that navigates is 1:2000.
Preferably, in step sl, it is respectively 100000 that at county level, township level, at village level, group grade boat, which fly striograph compression multiple,
~2500000 times, 5000~125000 times, 250~6250,25~625 times.
That is, the scale bar for the winged striograph that navigates is 1:2000, and computer screen resolution ratio is in millions, size
0.5 square metre or so, so at county level can generally compress 100000~2500000 times;Town grade can compress 5000~125000
Times;It is at village level to compress 250~6250 times;Group grade can compress 25~625 times, can adjust thumbnail pressure as the case may be
Demagnification number is flexibly handled.
According to one embodiment of present invention, in step s 4, corresponding navigate of " coordinate " value flies striograph no more than four.
Further, in step s 4, the corresponding data volume for navigating winged striograph of " coordinate " value is 80M~300M.
That is, every figure about 80M size after the winged striograph framing that navigates, the boat in a county fly striograph about 200G
To too high, the county of processor, memory, video card requirement for flying striograph to server of between 300G, being navigated with the method load of GIS itself
The grade dedicated 100,000 yuan of grade servers of confirmation of land right do not reach requirement.And in step s 4, corresponding navigate of " coordinate " value flies image
The data volume of figure is 80M~300M, since this kind of mode Loads Image, and quantity is few, and data volume is small, and the loading velocity is fast.
Preferably, at county level and following region at county level boat flew the striograph load time less than two minutes.
According to the present invention navigate flies the loading method of striograph as a result, by flying at county level, township level, at village level, group grade boat
Striograph merges according to different ratios be compressed into thumbnail respectively, and makes " navigate and fly image four angular coordinate attribute list ",
It can be improved to navigate and fly the loading velocity of striograph, it is slow to solve the winged striograph of GIS platform load boat for the search function of Optimization Platform
The problem of, it is widely applicable, speed-increasing effect is obvious.
The boat of embodiment flies striograph load software according to a second aspect of the present invention, comprising:
Preprocessing module, preprocessing module are used at county level, township level, at village level, group grade boat flying striograph respectively according to not
Same scale compression is at corresponding thumbnail;
Processing module, extracts the four angular coordinate system for the winged striograph that navigates, and production " navigates and flies image four angular coordinate attribute list ";
Execution module, when need to load at county level, township level, it is at village level, group grade boat fly striograph when, then load respectively it is at county level,
Township level, at village level, group grade boat fly the corresponding thumbnail of striograph, when needing boat of the load less than group grade region to fly striograph,
Then extracting needs to be loaded navigate to fly the coordinate range of striograph, and finds matching " the winged striograph four angular coordinate attribute of boat
Corresponding " coordinate " value in table ", corresponding navigate of load " coordinate " value fly striograph.
The winged striograph load software loading velocity of boat according to the present invention is fast, quality is high, widely applicable, is able to solve rural area
Aerial images figure is loaded in contractual right of land information management platform loads slow problem.
The aerial photography device of embodiment according to a third aspect of the present invention, the boat including embodiment according to a second aspect of the present invention fly shadow
As figure load software.Aerial photography device according to an embodiment of the present invention can be unmanned plane or other equipment of taking photo by plane, the aerial photography device are adopted
Image load is carried out with the winged striograph load software according to the above embodiment of the present invention that navigates, loading velocity is fast.
