Description
Technical field
The invention belongs to field of measuring technique, more particularly to quickly generate topographic map into figure based on high definition satellite remote-sensing image
Method.
Background technology
Topographic map mostly uses field digitized mapping and photogrammetric equal conventional means, wherein digitized mapping precision at figure
High but efficiency is low, photogrammetric to be limited by weather condition, and current preconsolidation stress is centering large-scale topographic map demand week
Phase is very short, and general unit of surveying mostly uses tactics of human sea, based on digitized mapping.
Existing GIS（GIS-Geographic Information System）Platform software, such as ArcGIS have been provided with more complete geographic information processing work(
Can, include the registration and fusion treatment of different-format striograph, to being registrated the cutting of image and being properly positioned display, and most
Topographic map systematic function afterwards.But in engineer application, topographic map use and acquisition mostly uses CAD platforms, and ArcGIS
Editor's acquisition function is weaker, the symbol of many complicated large scale topographical maps, linear, font and printout it is weaker than CAD and
Platform application range is few, thus the present invention must in conjunction with produce reality, Automation step by step, when saving a large amount of data processing
Between, for example striograph is in the correct display of CAD, the automatic cutting etc. of image.
State Intellectual Property Office disclosed on 04 02nd, 2014 application No. is CN201310386156.3, entitled base
In the patent of invention of the topographic map integration quick mapping method of high definition satellite image, disclose a kind of based on high definition satellite image
Topographic map integration quick mapping method, this method determines field operation mapping by the fusion to satellite image, Classification and Identification
Photo control point synchronously completes digitized mapping, Field mapping and photo control point acquisition in the wild；It is defended later with the color integration after registration
Star image is base map, and benefit paints field operation leakage and paints atural object, completes landform map generalization.The present invention is based on the topographic maps of high definition satellite image
Tune is painted, is permeated as controlling, mending three field operation steps such as survey by integrated quick mapping method, realizes and reduces field process amount
Target has the characteristics that the period is short compared with traditional aerial survey, and compared with traditional artificial measure, field process amount is few, puts into
The at low cost and period is short.
There are following technical problems for the above-mentioned prior art：Regulation and control, as controlling and mending survey during, be easy image mistake
Combination, to cause the error of mapping.Meanwhile the interference that bring such as life entity blocking can not be reduced.
Invention content
Present invention seek to address that in the prior art image be easy faulty combination, life entity bring at figure interfere the problem of.
The present invention is proposed quickly generates topographic map drawing methods based on high definition satellite remote-sensing image, by arrange life entity
It removes, carries out longitude and latitude combination again after figure is then carried out multilayer Stratified Imaging, improve precision of the topographic map at figure, reduce
What life entity was brought interferes at figure.It is few that extraneous life entity interference is generated to greatest extent, each figure layer precise overlay, to obtain
The purpose of high-precision topographic map.
In order to achieve the above-mentioned object of the invention, technical scheme is as follows：
Topographic map drawing methods are quickly generated based on high definition satellite remote-sensing image, are included the following steps：
A. it uses satellite to needing to be divided into n height above sea level layer at the shaped area height above sea level of figure, is labeled as 1~n；
B. it to three basic points of each layer of determination in step A, is respectively labeled as：A1, B1 and C1；A1, B1 and C1 ... An, Bn and
Cn；
C. each layer of three basic points are taken photo by plane, using the satellite or chromatic image of taking photo by plane of all kinds of resolution ratio to satellite
Or panchromatic image of taking photo by plane carries out fusion treatment；
D. it uses thermal energy survey meter to carry out thermal energy detection to each layer of life entity and is imaged；
E. step C is subjected to overlapping filtering with the figure in step D, obtains no life entity figure layer and is labeled as 1t, 2t ... nt；
F. it will obtain overlapping to form initial topographic map successively according to height above sea level without life entity figure layer 1t, 2t ... nt in step E；
G. repeat above step and obtain several initial maps, will several initial maps progress statistical procedures, obtain topographic map at
Figure.
Further, the fusion treatment in the step C of the present invention includes the following steps：
A. the chromatic image in Various types of data source and panchromatic image are uniformly corrected under a coordinate；
B. by chromatic image resampling so that the ratio between chromatic image and panchromatic image resolution ratio are 1:1、1:2 or 1:4；
C. the RGB wave bands of chromatic image are separated；
D. the RGB wave band images separated are merged with panchromatic image, obtains color integration image.
Further, carrying out layering to height above sea level in step A of the present invention refers to：3D moldings are carried out to landform, according to poster height
Degree carries out cross section segmentation；The height of each height above sea level layer is less than 0.01mm in delaminating process.
Further, in step B of the present invention to each layer of determining three basic point when, face that the lines of three basic points is formed
80% or more of area where height above sea level layer where product is at least three basic points.
Further, step E of the present invention overlapping filtering concrete operations be：By the figure of the figure of step C and step D
Shape carries out different mark colors respectively, labeled as being overlapped after different colors；The part for deleting the two colour superimposition, obtains nothing
Life entity figure layer.
Beneficial effects of the present invention：
（One）Topographic map is decomposed into two parts by the present invention at figure, and one is that multiple height above sea level layers is divided into take multiple measurements,
In addition statistics reduces its error.The interference of life entity is reduced by thermal energy detector simultaneously, provides a kind of pure ground
Shape figure.This topographic map only has fixed landform, and the life entity not moved is interfered, and increases precision of the topographic map at figure
And accuracy.
（Two）All kinds of acquisition platforms, various times, all kinds of resolution ratio can be used in the color data source of fusion treatment of the present invention
Chromatic image, reduce data buying threshold and cost, expand the range that data utilize, efficiently use miscellaneous satellite
Image resource；To after fusion fusion evaluation carry out Classification and Identification, will be unable to identification atural object, as photo control point have it is important
The atural object of location information carries out field operation digital mapping, can enhance topographic map and be presented to the emphasis of importantly object, also avoids pair
Field operation mapping within the scope of full figure, reduces field process amount, improves into figure efficiency；Meanwhile the chromatic image after fusion, both had
There is higher resolution ratio, and there is color information so that the Objects recognition and collection effect of topographic map are more preferable.
（Three）Two picture labels are not had different colors, after identical colour superimposition by the method that the present invention uses aberration overlapping
Variation, can fast and accurately distinguish the part of overlapping.In the present invention, you can quickly by life entity to topographic map
Influence eliminated.So as to obtain more accurate topographic map.
