s110: and identifying the content of the catalog drawing of the preset engineering project, and determining the name of each engineering drawing of the preset engineering project.
It should be noted that the preset engineering project may be any type of engineering project, for example: subway construction projects, house building projects, bridge engineering projects and the like, and the contents of engineering drawings are different according to the different categories of each project. The catalog drawing can be a drawing which records the corresponding relation between the name and the identification of each engineering drawing in a form mode in the engineering drawings, wherein the identification of the engineering drawing can be information such as the code, the drawing number or the storage position of each drawing, and the engineering drawing which needs to be called or inquired can be determined according to the identification of the engineering drawing. The content of the catalog drawing can be obtained by carrying out content identification on the catalog drawing of the preset engineering project, and the name of each engineering drawing of the preset engineering project is determined according to the content in the catalog drawing.

When the three-dimensional shape and size are expressed by using a plan view, a three-view method, i.e., a front view, a side view, and a top view, may be used. According to the principle of three views, the construction engineering drawing can be divided into a building plan view, an elevation view and a section view, and further comprises a building detailed view and a structural construction drawing. The construction plan can be divided into a general plan and a plan expressing a specific project.
For example, when the preset engineering project is a subway construction project, the engineering drawing may include: a catalog, a design description, a detailed view, a plan view (a floor, a middle plate, a ceiling, a transfer station, a station hall floor, a station floor, an underground three floor, and an underground four floor), a cross-sectional view (a bar graph, a structure graph, and others), a longitudinal-sectional view (a bar graph, a structure graph, and others), a floor sequence diagram, and the like.
It should be noted that the specific classification may be set according to the operation of calling, querying, and the like after the classification is completed, which is not limited herein.
In the engineering drawing processing method provided by the embodiment of the application, the name of each engineering drawing of a preset engineering project can be determined by identifying the content of the catalog drawing of the preset engineering project; according to the name of each engineering drawing, the classification model based on natural language processing trained in advance is adopted, the classification of each engineering drawing can be determined, the classification model based on natural language processing is used for classification, a more accurate classification result can be obtained, the accuracy of drawing classification is improved, the working efficiency of workers can be improved, and the time consumed by calling and inquiring is saved.

s210: and determining the name of the target engineering drawing corresponding to the target type according to the target type to be inquired and the first corresponding relation.
It should be noted that the target type to be queried may be a target type to be called or queried after the engineering drawings are classified, that is, one or more types of the categories of the engineering drawings. After the target type to be queried is determined, the name of the target engineering drawing corresponding to the target type can be determined according to the target type and the first corresponding relation, and the name of the target engineering drawing is the name of all the engineering drawings in the target type.
S220: and determining the identifier of the target engineering drawing according to the name of the target engineering drawing and the second corresponding relation.
It should be noted that after determining the names of all the target engineering drawings, the identifiers of the target engineering drawings corresponding to the names of the target engineering drawings may be determined according to the second correspondence, for example: and corresponding to the information of the code, the number, the storage position and the like of the drawing.
S230: and searching the target engineering drawing according to the identification of the target engineering drawing.
After the identification of the target engineering drawing is determined, because the identification of each engineering drawing is unique, the target engineering drawing can be determined according to the identification of the target engineering drawing, and if the identification is a code or a drawing number, the corresponding engineering drawing can be inquired according to the code or the drawing number; if the location is the storage location, the engineering drawing stored in the storage location can be called as the target engineering drawing.
For example, when a worker needs to call or query a certain type of engineering drawing, for example: and (3) a stair diagram, wherein the type of the target to be queried is the type of the stair diagram, and the names of all the engineering drawings belonging to the type of the stair diagram can be determined according to the stair diagram and the names of the engineering drawings corresponding to the stair diagram in the first corresponding relation, for example: a first layer of stairs, a second layer of stairs, an underground layer of stairs and the like; according to the determined names of the engineering drawings and the identifications of the engineering drawings corresponding to the engineering drawing names in the second corresponding relationship, the identifications of the engineering drawings can be determined, for example: the drawing numbers of these drawings, etc.; according to the identification of the engineering drawings, the actually corresponding engineering drawings can be determined, and the engineering drawings are the target engineering drawings, namely the engineering drawings belonging to the type of stair drawings.
Optionally, the method further comprises:
and identifying the content of the target engineering drawing to obtain an identification result.
It should be noted that, after the target engineering drawing is determined, the content in the target drawing may be identified, and relevant elements in the target drawing are extracted, for example: the method comprises the following steps of title union and meeting signposts, scales, positioning axes and numbers, dimension labels, elevations, index symbols, detailed chart symbols, north pointers, specific images and the like, wherein one or more elements are used as identification results obtained after content identification according to actual calling or inquiring requirements.
The specific implementation of the specific catalog drawing provided in the present application is explained below by specific examples.
Fig. 3 is a schematic flowchart of a process of determining a catalog drawing according to an embodiment of the present application, please refer to fig. 3, S110: before content recognition is carried out on the catalog drawings of the preset engineering projects and the name of each engineering drawing of the preset engineering projects is determined, the method further comprises the following steps:
s310: and determining a drawing with tabular data from drawings of a preset engineering project.
It should be noted that all drawings in the preset engineering project may be screened and determined by image recognition, text detection, or a preset algorithm program, and the drawings with table data therein may be found. The table data can be a chart, a digital table or any type of related data with a rule block diagram.
S320: and judging whether the table data in the drawing with the table data is the catalogue table data.
After the drawings with the table data are determined, whether the table data are the table data or not can be judged according to the format of the preset table data, and the table data are data which represent the corresponding relation between the name and the identification of each engineering drawing in a table form.
S330: if yes, determining the drawing with the table data as the catalogue drawing.
If the table data obtained by the determination of the S320 is catalog table data, the drawing with the table data may be used as the catalog drawing; accordingly, if the obtained form data is not catalog form data, the drawing having the form data is not a catalog drawing.
The specific implementation process for determining the name of the engineering drawing provided in the present application is explained below by specific examples.
Fig. 4 is a schematic flowchart of a process for determining names of engineering drawings according to an embodiment of the present application, please refer to fig. 4, S110: the method comprises the following steps of carrying out content identification on a catalog drawing of a preset engineering project, and determining the name of each engineering drawing of the preset engineering project, wherein the name comprises the following steps:

It should be noted that, content identification may be performed on the content in the catalog drawing through image identification, text detection, or a preset algorithm program, and each type of data in the catalog drawing is extracted, for example: the name of each engineering drawing, the identification of each engineering drawing and other information of each engineering drawing; unifying the formats of each type of data, such as the names of engineering drawings in catalog drawings, wherein the expression modes of the data may have various types such as English, Chinese and the like, unifying the data types of different formats, and unifying the data types into Chinese for expression; correspondingly, the identifier of each engineering drawing and other information of each engineering drawing can be unified in format, for example, the identifier of a part of the drawings is a drawing number, and the identifier of a part of the drawings is a code, and the information is unified into the same format so as to be convenient for subsequent classification processing.
S420: and determining the name of each engineering drawing from the normalized content.
It should be noted that the name of each engineering drawing in the unified format may be determined from all normalized contents, and optionally, in the process of classifying the engineering drawings in S120, the names of the engineering drawings in the unified format may be input into the classification model for classification.
For example, after content identification is performed on The catalog drawing, The names of The engineering drawings in The obtained specific identification content are "first-floor building", "2 nd-floor building", and The third-floor building ", and The formats of The names of The drawings can be unified into" first-floor building "," second-floor building ", and" third-floor building "through normalization processing. Correspondingly, if the formats of the identifiers or other contents in the catalog drawing are not uniform, the formats of the data can be normalized by adopting a similar method to obtain a uniform recognition result.
Alternatively, the specific process of determining the category of each engineering drawing by using the pre-trained classification model based on natural language processing in the present application is explained by the following specific embodiments.
