Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
According to the application, the embodiment provides a wall column identification method in the construction drawing. Alternatively, in the embodiment of the present application, the method for identifying a wall column in a construction drawing can be applied to a hardware environment formed by the terminal 101 and the server 102 as shown in fig. 1. As shown in fig. 1, a server 102 is connected to a terminal 101 through a network, and may be used to provide services (such as application services) for the terminal or a client installed on the terminal, and a database may be provided on the server or separately from the server, and may be used to provide data storage services for the server 102, where the network includes but is not limited to: the terminal 101 is not limited to a PC, a mobile phone, a tablet computer, and the like.
The method for identifying the wall column in the construction drawing according to the embodiment of the present application may be executed by the server 102, may also be executed by the terminal 101, and may also be executed by both the server 102 and the terminal 101. The terminal 101 executes the method for identifying a wall column in the construction drawing according to the embodiment of the present application, or may be executed by a client installed thereon.
Taking a terminal to execute the method for identifying a wall column in a building drawing of the embodiment of the present application as an example, fig. 2 is a schematic flow chart of an optional method for identifying a wall column in a building drawing according to the embodiment of the present application, and as shown in fig. 2, the flow of the method may include the following steps:
In some embodiments, the building drawing to be identified may be uploaded to the terminal after the designer finishes designing and when the building drawing needs to be identified; alternatively, the identification may be acquired from a database when the relevant person identifies the construction drawing. The database stores a plurality of building drawings to be identified, and related personnel can select one of the building drawings to be identified according to the drawing name of the building drawing to be identified.
By way of example, the construction drawing to be identified may be, but is not limited to, a drawing for an airport, train station, bus stop, office building, residential building, hospital, museum, tourist attraction, church, school, park, or the like.
In some embodiments, in the design of a building drawing, in order to facilitate management and drawing, the design is often performed according to layers, and different types of primitives are set in each layer. Based on the method, after the building drawing to be identified is obtained, the first layers including the line primitives can be determined according to the types of the primitives in the layers, and then the target line primitive set in each first layer is determined.
There are various types of primitives, such as line primitives, fill primitives, and annotation graph sources.
In an optional embodiment, determining the set of line elements in the first layer of the construction drawing comprises:
acquiring the layer name of the first layer; determining a line primitive including the layer name in the primitive information as a target line primitive; and determining the set of target line primitives as the set of target line primitives.
In some embodiments, when a building drawing is designed, layer names are often reset for different layers to distinguish the layers, and when a primitive in each layer is drawn, the layer name of the layer where the primitive is located is carried. Therefore, according to the layer name of the first layer, a line primitive including the layer name can be determined from the primitive information of the building drawing and is used as a target line primitive.
In some embodiments, because the primitives in the first layer include line primitives, when the building drawing is drawn, the wall pillars are often drawn in the form of closed polygons, see fig. 3, for example, the closed polygons may be rectangles, L-shaped figures, or other closed shapes. Therefore, after the target line primitive set in the first layer is determined, the closed polygon in the first layer can be determined according to the target line primitive set in the first layer.
Specifically, determining a closed polygon set in the first layer according to the target line primitive set includes:
acquiring a starting point coordinate and an end point coordinate of each target line primitive in the target line primitive set; and determining a closed polygon in the first layer according to the start point coordinate and the end point coordinate to obtain the closed polygon set, wherein one target line primitive coincides with the start point coordinate and the other target line primitive coincides with the end point coordinate for any target line primitive in the closed polygon.
In some embodiments, because the first layer includes the target line primitive set, in the process of drawing the building drawing, the wall pillar outline is often obtained after the wall pillar outline is drawn as a closed polygon through the line primitives. Therefore, the start point coordinate and the end point coordinate of each target line primitive in the target line primitive set can be determined, and then whether a plurality of line primitives form a closed polygon or not can be judged based on the start point coordinate and the end point coordinate of each target line primitive. Typically, there is one target line primitive coincident with its start point coordinates and another target line primitive coincident with its end point coordinates in any one target line primitive in a closed polygon.
In an optional embodiment, before determining the set of closed polygons in the first layer according to the target line primitive set, the method includes:
calculating the length of each target line primitive segment in the target line primitive set; if the length of the line segment does not meet the preset wall column length value, determining that the first image layer does not include the wall column; and if the length of the line segment meets the preset wall column length value, executing the target line primitive set, and determining a closed polygon set in the first layer.
In some embodiments, since the wall studs play an important role in the building, when the building drawing is designed, the length of the line segment of the line primitive included in the wall stud profile is longer, and therefore, whether the wall studs are included in the first map layer can be determined by determining whether the length of the line segment meets a preset value of the length of the wall studs.
And 204, if the characteristic parameters of the closed polygon set meet the first recognition condition in the first layer, determining that the closed polygon in the first layer is a wall column outline.
In some embodiments, in the construction drawing, not all the closed polygons are closed polygons corresponding to the wall studs, for example, the design of the balcony in the construction drawing also exists in the form of closed polygons, and therefore, it is necessary to filter the set of closed polygons determined in the first layer, and determine that the closed polygons in the first layer whose characteristic parameters satisfy the first identification condition are the wall stud outlines.
Specifically, the characteristic parameters of the closed polygon set include a first number of closed polygons in the closed polygon set, a second number of the target line primitives in the closed polygon set, and a first area of each closed polygon in the closed polygon set;
the first identification condition in the first image layer includes: the first number is larger than a first preset value, the ratio of the second number to the third number of the target line primitives in the first layer is larger than or equal to a second preset value, the number of the first areas larger than the first preset area is smaller than the third preset value, and the number of the first areas smaller than the second preset area is smaller than a fourth preset value.
In an optional embodiment, the method further comprises: determining a target filling primitive set in any second layer of the building drawing, wherein the second layer comprises filling primitives; determining a second area of each target fill primitive in the set of target fill primitives; if the second area meets a second recognition condition in the second layer, determining that the filled graphics primitives in the second layer are wall column filling; and determining the level of the wall column profile according to the wall column filling and the wall column profile.
In some embodiments, the wall studs designed in the construction drawings are often filled with contents (such as filling colors or graphics) in addition to the wall stud outline, so as to distinguish the wall studs from other wall studs and facilitate the user to view the wall studs. And determining the wall column filling in each second layer by determining a target filling primitive set in the second layer based on the filling content which often exists in the form of filling primitives.
Specifically, whether the filling primitives in the second layer are wall column filling or not can be determined by judging whether the second area of each target filling primitive meets the second recognition condition in the second layer or not.
After the second area of each target filling primitive is obtained, a fourth number of the second areas in the second layer may be counted.
Further, the second identification condition in the second image layer includes: the ratio of the number of the target filling primitives with the second areas larger than the second preset area value to the fourth number in the second layer is smaller than a fifth preset value, and the ratio of the number of the target filling primitives with the second areas smaller than the third preset area value to the fourth number is smaller than a sixth preset value. And the third preset area value is smaller than the second preset area value.
And the second layer is a layer comprising filling primitives. Since the filling primitives are filled in the wall stud outline, the first area of the wall stud outline within the preset range of each filling primitive can be used as the second area of the filling primitive.
Further, the determining the level of the wall stud profile according to the wall stud filling and the wall stud profile comprises:
determining the wall columns with the wall column profiles of which the distances between the wall column profiles are smaller than a preset coincidence threshold value to be the same level; determining the filling proportion of the wall column filling within the preset distance of each wall column profile; if the filling proportion is smaller than a preset filling threshold value, determining that the wall column profile is a lower-layer wall column; and if the filling proportion is larger than or equal to a preset filling threshold value, determining that the wall column profile is an upper-layer wall column.
In some embodiments, the building drawing is generally a two-dimensional drawing, and in a building with multiple layers, the filling contents of the lower layer are generally covered by the filling contents of the upper layer, so that the filling contents of the lower layer cannot be completely displayed. Based on the method, the level of the wall column outline can be determined through the distance between the wall column outlines and the filling proportion of wall column filling.
The method for identifying the wall column in the building drawing screens out filling primitives which accord with the wall column filling characteristics from all the filling primitives layer by layer; positioning line segment primitives which accord with the line segment characteristics of the wall column one by one from all the line segment lists, and splicing the line segment primitives into a wall column outline; and distinguishing the upper layer wall column from the lower layer wall column according to the filling primitives and the wall column outline. Generally, the wall columns are divided into two types, namely a standard layer wall column and a transfer layer, the upper wall column and the lower wall column are of the same type, most of the wall columns are applied to buildings integrating commercial houses, and the lower layer wall column is large and the upper layer wall column is small in general. Based on this, the specific identification process includes:
firstly, identifying wall column filling;
1. extracting a layer list from all the filling primitives;
2. circularly processing each layer in the layer list, and screening filling primitives in the current layer according to the layer name attribute of the primitives;
3. counting the number of the graphic elements with the area larger than 4 square meters, calculating the proportion of the number to the total number of the filling graphic elements of the current layer, and if the number is larger than a certain proportion, judging that the filling is not wall column filling;
4. counting the number of the primitive areas smaller than 0.12 square meter, calculating the proportion of the number to the total number of the filling primitives of the current layer, and if the number is larger than a certain proportion, judging that the filling is not wall column filling;
5. if the check is passed, it is determined that the wall stud is filled. The wall studs identified herein are filled for subsequent discrimination of upper and lower wall studs.
Secondly, identifying a wall column outline list;
1. extracting a layer list from all line segment primitives;
2. circularly processing each layer in the layer list, and screening line segment primitives in the current layer according to the layer name attribute of the primitives;
3. calculating the length of the line segment according to the coordinates of the starting point and the end point of the line segment;
4. counting the number of the line segment lengths smaller than 399, calculating the proportion of the number to the total number of the line segment primitives of the current layer, and if the number is larger than a certain proportion, continuing to process the next layer;
5. counting the number a of the line segment lengths larger than 1000 and the number b of the line segment lengths larger than 7000, calculating the ratio of the number b to the number a, and if the ratio is larger than a certain ratio, continuing to process a next layer;
6. splicing a closed polygon and a non-closed multi-segment line according to the end-to-end connection of the coordinates of the segment primitives;
7. judging the number of the closed polygons, and if the number of the closed polygons is less than a certain number, continuing to process the next image layer;
8. calculating the number of line segments participating in forming the closed polygon and the proportion of the total number of the line segments in the current layer, and if the number of the line segments is smaller than a certain proportion, continuing to process the next layer;
9. counting the number of the closed polygons with the area larger than 4 square meters, calculating the proportion of the number to the total number of the closed polygons, and if the number is larger than a certain proportion, judging that the wall column is not filled;
10. counting the number of the closed polygons with the area smaller than 0.12 square meter, calculating the proportion of the number to the total number of the closed polygons, and if the number is larger than a certain proportion, judging that the wall column is not filled;
11. if the above check is passed, it is determined as a wall stud profile.
Thirdly, distinguishing upper and lower layer wall columns (the situation of converting the layer wall columns);
the upper layer wall column and the lower layer wall column are distinguished mainly by filling; when the lower wall stud line and the upper wall stud line are filled, the upper wall stud line is filled in a filling mode SOLID. The detailed process is as follows:
1. for each wall stud polygon, find nearby polygons,
1.1. if there are no other polygons nearby,
1.2 or the nearby polygons completely coincide (less than the set coincidence threshold),
1.3 the polygon is considered to belong to the wall column of the upper layer and the lower layer
2. Then judging the filling near the polygon of the wall column,
2.1, if the filling is not carried out, judging that the lower-layer wall column is a lower-layer wall column;
2.2, if the wall column is filled, and the wall column is completely filled (the ratio is more than the set threshold value), judging that the wall column is an upper-layer wall column,
2.3, if the filling exists and the filling proportion is smaller than the set threshold value, judging that the lower-layer wall column is the lower-layer wall column
The final result divides the wall stud profile list into two wall stud lists: the upper layer of wall column profile and the lower layer of wall column profile.
