Description
Technical field
The present invention relates to a kind of overall construction site plan production methods based on orthography data, are particularly suitable for building item
Mesh is constructed general plan application, can true, intuitive, high definition show that geometric position of the construction main structure at the scene in environment is closed
System, belongs to building engineering field.
Background technique
Currently, to improve, construction management of project is horizontal and management philosophy, each project in construction can make a construction
General arrangement plan, for show the construction repair of this project, Design of Construction Organization, arrangement and method for construction, construction speed,
The main contents such as resource planning, it can be seen that always flat figure production quality and depth directly affect item construction management to project construction
It is horizontal.Currently, the production method of domestic construction main flat graph mainly has: first is that directlying adopt designing institute provides grating map as total
Figure, the designed lines of the figure main presentation engineering project cannot check the geographical environment on route periphery；Second is that with the satellite of downloading
Figure is used as map, is superimposed designed lines figure, the data changed plan with satellite image mostly several years ago, cannot grasp live ground very well
The case where environment such as object, landforms, so that its expression effect is unsatisfactory；Third is that the involvement element of total figure is less, most total figures are only
The position for having incorporated route red line, having faced facility greatly, can not intuitively express very much project applies a group arrangement.With construction row
Industry information development is higher and higher, delivers construction information and the integrated level also the next high, and existing total figure has been unable to meet to use and need
It asks, needs to merge more information element, be preferably construction production clothes to improve total figure to the expressivity of project integral layout
Business.
Summary of the invention
The present invention provides a kind of overall construction site plan production method based on orthography data, to solve to apply with building
Industrial and commercial bank's industry information development is higher and higher, delivers construction information and the integrated level also the next high, existing total figure, which has been unable to meet, to be made
The problem of with demand.
To solve the above problems, such a overall construction site plan production method based on orthography data of proposed adoption,
The specific method is as follows:

The orthography of the satellite image of downloading and unmanned aerial survey production is saved under same file respectively, hereinafter referred to as
Total map file；
Cutting edge processing is carried out to unmanned orthography using global mapper first, the underproof number in edge is carried out
It deletes；
Data set is inlayed in arcgis creation, dataset name, the identical coordinate system of setting and pixel class are inlayed in input
Type gets up two data fusions, and exports；
4) DOM and design drawing fusion
Design drawing is edited in CAD software, unwanted atural object data is deleted, retains required boundary lines of roads,
Main structure line is saved into total figure file；
In global mapper, according to red line figure and main structure coordinate that designing institute provides, setting and orthography
Identical coordinate system carries out geographical calibration to design drawing；
By after calibration image and design drawing imported into cad simultaneously, according to coordinate matching by DOM data and design drawing into
Row association integrates, and the ratio of the two data is 1:1；
5) face building for facility BIM model greatly
Building model in conjunction with the case where live construction land, needed for being established by revit software partitioning；
6) Enhanced expressing of multisource data fusion
The BIM Model Fusion of facility will be faced greatly into total figure；In conjunction with the deployment at scene, drafting road changes shifting, sidewalk is planned,
Construction red line information；Using the mobilization of mind map combing project, it is integrated into total figure in the form of highly concentrated contract drawing；
It is arranged according to applying group, classifying rationally work area；
In preceding method, unmanned plane field acquisition image specific requirement is as follows:
Weather, surrounding enviroment in conjunction with construction site select the flight optimization period to carry out aerophotogrammetric field work；
According to the size for surveying area, Reasonable Arrangement photo control point, photo control point is laid alternate using 500mm*500mm black-white colors
Navigation mark measures the coordinate of each photo control point as land marking；
Aerial survey task is set, place relatively gentler for city or topography, around without high-voltage line, large-scale wireless base station,
Signal tower, image is acquired using full-automatic flight；Mountain area is acquired using manual offline mode.
In preceding method, it is as follows that aerophotogrammetry data handles detailed process:
Aerophotogrammetry data pretreatment, checks whether aerial images have underproof image, and unqualified image is deleted；It checks
Whether the pos data of photo control point are qualified；The lower product of empty three mass is selected, is quickly pre-processed, entire survey area is detected
Data whether all standing, if having cavity, garland situation；If there is above situation, carries out mending survey or resurvey；
After pretreatment is qualified, into aerophotogrammetry data process flow, raw video data and the pos data at control point are imported
In aerial survey software, according to the coordinate system where pos data, coordinate parameters are set, it is ensured that image and pos data coordinates system
One；
Control point is oriented, in empty trilete rays, according to the number at control point, successively control point is carried out at thorn point
Reason, the crosshair centering of all images occurred in specially same control point to photo control point center.
Compared with prior art, the method for the invention has that image collection speed is fast, the with short production cycle, update cycle
Fastly, image definition is high, really can intuitively the express major project positional relationship of environment, required at low cost, easy at the scene
In promote and apply many advantages, such as, for the total figure of small scene, directlys adopt aerial survey of unmanned aerial vehicle technology and obtain high definition orthography
As the basic data of total figure, project longer for route is merged using satellite image with unmanned plane orthography, really
Protect large scene effective use, line midline and the mode for facing the displaying of Facilities Construction position high definition greatly.Company is multiple at present
Application, the highly recognition for obtaining construction unit, establishing unit and designing unit, the construction to engineering project are carried out in project
General arrangement and deployment have important directive significance and promotional value.
