Description
Technical field
The present invention relates to a kind of drawing search method, be specifically related to a kind of CAD drawing search method based on GIS technology.
Background technology
Be widely used in CAD system all kinds of manufacturing business at home and abroad, particularly have a wide range of applications in the field such as urban design, architectural design.Along with the widespread use of CAD drawing, drawing accumulates in a large number, how effectively to manage these drawings, quick-searching becomes one of focus instantly studied.
The retrieval of current text based CAD drawing is from drawing, extract the crucial text message can summarizing its content, and as designer, design content keyword etc., called after designation of drawing or set up corresponding contingency table, inquires about drawing with it.But this retrieval mode limits by strict naming standard, different production unit and producer, as do not observed this standard well, will directly cause the decline of recall precision and accuracy.
CAD drawing retrieval content-based at present, according to spatial relationship between the geological information of the figure in drawing information and different parts, drawing is retrieved, first geometric properties information and the spatial relationship information thereof of drawing is extracted, be saved in fixed character storehouse as its characteristic information, when user designs new drawing, submit to sketch to system and automatically contrast through system, filter out similar drawing.This retrieval mode, is mostly angles from deviser, and consider the reusability of existing drawing, complexity is high, and analytical algorithm is comparatively complicated.
In actual applications, except the deviser of drawing, a lot of non-professional user is also had to carry out the retrieval of drawing according to business demand, therefore, need a kind of convenient, efficient CAD drawing search method, layout design person can be given simultaneously, approach that user provides a quick-searching CAD drawing
Summary of the invention
The present invention is directed to above-mentioned prior art Problems existing to make improvements, namely the technical problem to be solved in the present invention is to provide a kind of CAD drawing search method based on GIS technology,
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
Based on a CAD drawing search method for GIS technology, comprise the steps:
S1, first need in management of blueprint process, set up the index relative of " figure paper code---object's position ";
S2, obtain the edge feature point of content institute's reflection object position of drawing to be associated, obtained the coordinate of each unique point by the position mark in drawing;
S3, generate the relationship maps of figure paper code and object's position according to the coordinate information obtained, these mapping relations are stored as a GIS format space index file in the mode of GIS graphical element;
S4, when carrying out drawing retrieval, specify interested region by the mode of carrying out region drafting in generalized information system, thus relationship maps concordance list find out all drawings with this zone association.
In addition, retrieving can be expanded as directly being located position or the certain buffering range region of periphery by the GPS positioning system of mobile terminal; Relationship maps concordance list find out all drawings with this zone association thus.
Further, generate the relationship maps of figure paper code and object's position according to the coordinate information obtained, these mapping relations are stored as a GIS format space index file step in the mode of GIS graphical element:
Layer is resembled faced by a newly-built GIS form, for storing the index layer of " figure paper code---object's position " mapping relations, as: index.shp is that it increases an attribute field for storage figure paper code, as: Image_NO;
According to obtained each angular coordinate information, in index layer index.shp, draw a polygon key element, and drawing number is stored with this polygonal attribute field Image_NO.
Further, when carrying out drawing retrieval, interested region is specified by the mode of carrying out region drafting in generalized information system, relationship maps concordance list find out all drawing steps with this zone association thus: in generalized information system, the instrument customized is utilized to draw a polygon, the interested region of this polygon specified by user; Face key element of having living space in face, space key element corresponding for this region and index layer index.shp compares by system, by in index layer index.shp, the key element showed as " crossing ", " comprising ", " involved " with the former topological relation all screens.
Further, position or the certain buffering range region of periphery is directly located by the GPS positioning system of mobile terminal; Relationship maps concordance list find out all drawing steps with this zone association thus: march to the region wishing to check drawing in hand-held mobile terminal, or building, near installations and facilities time, utilize the GPS positioning function consumer positioning position of mobile terminal; The range size in the region desirably inquired about, carries out the buffering of certain distance to position, form buffering polygon, this polygon comprises the region or crossing with it interested to user; Face key element of having living space in face, space key element corresponding for this region and index layer index.shp compares by system, by in index layer index.shp, the key element showed as " crossing ", " comprising ", " involved " with the former topological relation all screens.
The invention has the beneficial effects as follows index information all by obtaining in management of blueprint in early stage process, only relevant to locus, do not rely on algorithm and the pattern of the complexity built on pattern analysis basis, result for retrieval has strict uniqueness;
Index information in the present invention is all by obtaining in management of blueprint in early stage process, do not relate in retrieving the identification of drawing content and analysis, therefore do not limit by the form of associated drawing, drawing can store with any file mode checked, as PDF, JPG form.
CAD drawing in the present invention refers generally to the drawing including certain area spatial positional information, mostly is plane design drawing, and this method can be used to carry out drawing association and retrieval.In addition, separately there is the drawing of two types also can include category based on GIS technology retrieval in: 1) include locus but the drawing of a key element may be shown as in generalized information system, as the relevant design drawing of certain building under small scale, for such drawing, can be numbered and be write direct in the attribute field of a feature object, be realized associate management; 2) the universal design drawing of locus is not comprised, as the part of appliance of certain model, for such drawing, can comprehensively retrieve based on text and GIS technology two kinds of methods, that is: the model code that can identify this part of appliance writes in the device attribute field in designation of drawing and generalized information system simultaneously, in generalized information system, inquire about the part of appliance that any one is of the same type, all can retrieve relative drawing.
To sum up, the present invention can be used for mobile patrol officer and has access to figure paper material in real time, promotes O&M efficiency, effectively solves the problem in the past by text or content retrieval drawing inefficiency.
