Full production, coal-mining subsidence, which are administered, brings problems.
The content of the invention
The present invention is in order to solve the above problems, there is provided the nested conversion method of a kind of ground satellite image and underworkings.
The present invention takes following technical scheme：A kind of nested conversion method of ground satellite image and underworkings, specifically
Switch process is as follows：
101. loading and the editing and processing of satellite image；The satellite image treated by network satellite image in transition region enters
Row framing, graduation are downloaded, and form 25 width satellite image pictures, are then loaded into CAD software and are carried out picture merging, splicing and volume
Collect processing；
102. field photogrammetric control point surveying；According to region landform to be converted, chosen respectively in view picture satellite mapping in region to be converted
Field photo control point mapping is carried out with the obvious measurement point of feature；
103. the correction of single width image is handled；Measurement photo control point exhibition is painted in CAD program, at the same every width photograph is relative
The characteristic point answered is done in the same fashion triangle connection, is calculated by similarity of maps contrast and image calibration parameter,
Three parameters of relative position, scaling, the anglec of rotation of figure are drawn, then figure is calibrated；
104. view picture pattern fits；After carrying out accurate calibration to every width image, again to each image in CAD program
Figure is spliced, figure corner is fitted and editing and processing, the image figure formed in a view picture region；
105. the well accurate nesting of figure and conversion up and down；Respectively in satellite image figure and down-hole mining engineering plan
Selected characteristic point connects into two polygonal shapes, first according to the position of two polygonal shapes, size and shape in step 103
Shape asks for three relative position, the anglec of rotation, scaling parameters of figure, and satellite shadow is realized in CAD by three parameters
As accurate nested with underworkings plan.
In step 102, there is the obvious measurement point of feature to refer to construction of structures or road turn top in satellite image picture
Point.
The concrete operation step that figure is calibrated in step 103 is as follows：
1）Photo control point coordinate plotting will be measured in CAD program, and carry out triangle connection, equally, in CAD satellite image pictures
Midpoint takes the point coordinates of the same name with photo control point and carries out triangle and is connected；
2）Measure the length of side of two triangles respectively in CAD, calculate the scale parameter between three length of sides and take its average value,
Determine scaling parameter；
3）Measure the length of side orientation of two triangles respectively in CAD, calculate the azimuthal difference of three length of sides and take it average
Value, determines rotation angle parameter；
4）Calculated respectively in CAD and inverse is carried out to two triangular apex coordinates, calculate corresponding summit displacement
With azimuth and take its average value, determine displaced posi parameter.
Compared with prior art, the present invention makes full use of network satellite image, and field carries out part photogrammetric control point surveying, interior industry
The processing procedures such as image editing processing, the correction of interior industry single width image, the calculating of view picture pattern fits, nested parameter are taken, it is accurate real
Apply the conversion nested with network satellite image map of roadway plan under mine.
