Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention.
Example one
As shown in fig. 1, it is a flow chart of steps of a column bulk sample data reproduction method of the present invention, including the following steps:
step S101, identifying required graph elements from a column thumbnail; in an actual scene, a design drawing generated by design software such as a CAD is usually used in the bar chart, for example, in the bar chart of the CAD design, a required layer needs to be selected from the bar chart, and then a required primitive element is filtered from each layer element according to the type of the metadata information. As shown in fig. 2, the primitive elements required in the technical solution of the present application include labels, table lines, column edge lines, and reinforcement lines, where the reinforcement lines include a reinforcement shape detailed diagram and a reinforcement thumbnail, and the column edge lines are usually drawn on the periphery of the reinforcement thumbnail.
And S102, combining the information of the graph elements to form at least one processing area.
According to the common drawing specifications, the column thumbnail can be divided into two ways, and as shown in fig. 3, if a table line exists in the identified drawing element, an area consisting of only one set of the reinforcement line, the column edge line and the table line related to the label is taken as a processing area (as shown in fig. 4). As shown in fig. 5, if there is no table line in the identified map element, the area including only one set of the reinforcement line, the column boundary line, and the associated label is used as a processing area (as shown in fig. 6).
And S103, preprocessing the pixel in the processing area.
Specifically, the preprocessing of the primitive elements includes the following steps, because a designer draws a design drawing through industrial software, there may be a case where the operation is not standard and the drawing is not performed according to drawing rules, for example, a closed column boundary line that should be drawn by one line segment on the periphery of a steel bar big sample drawing is drawn by a plurality of line segments or is not completely closed in an actual operation, and at this time, the column boundary lines are processed to be connected with each other to form a closed area.
And judging the acquired pixel elements, filtering the irrelevant labels, and eliminating unnecessary character information and label lines. For example, the text information is excluded from the reinforcing bar information format, the column name information format, and the floor information format which do not comply with the specifications. As also shown in FIG. 7, the useless marking lines indicating the width and height indicated by the arrows in the figure need to be excluded. The labels are classified into column full-page sample names (B103), label lines (B104), stirrup labels (B105), longitudinal bar labels (B106) and floor information (B107) according to the label characteristics, as shown in FIG. 8.
At the same time, the filtering of useless redundant reinforcing steel wires is required, such as: too short a wire (length less than 150 mm), a repeated wire (one wire is excluded from the two wires in the figure) and a longitudinal bar with too small a wire diameter (diameter less than 4 mm). And the steel bar line outside the side line of the column and in the processing area is used as a steel bar shape detailed graph for subsequent judgment.
Step S104, identifying stirrups and lacing wires in the processing area;
firstly, dividing the intersecting marking lines in the processing area map elements into the same group, and associating the group of marking lines with the corresponding marking information, so that the corresponding marking information can be found for the steel bar lines intersecting the marking lines in the subsequent processing process. Then, identifying the reinforcement line which can form a head-to-tail closed pattern in a clockwise or anticlockwise direction from any starting point in the reinforcement big sample graph as a stirrup (C101, as shown in figure 9); and identifying the reinforcing steel bar lines which cannot be connected end to end in the reinforcing steel bar big picture as the tie bars (C102, shown in figure 10). The same method is adopted to identify the steel bar line in the steel bar shape detail drawing, and the in-situ stirrup and the in-situ tie bar are distinguished (C103, shown in figure 11).
And S105, calculating the position of the longitudinal rib in the processing area in a specific way:
step A1: reducing a closed area formed by the column sidelines to enable the column sidelines to be overlapped with the peripheral outline of the reinforcing steel bar line; because the periphery of the steel bar rough pattern is provided with the closed area formed by the column sidelines to represent the whole outline of the steel bar rough pattern, in order to calculate the position of the longitudinal bar conveniently, the calculation scheme of the application positions the position of the longitudinal bar by using the column sidelines as a reference object and records the position information of the longitudinal bar on the column sidelines. Therefore, the closed area formed by the column sidelines needs to be reduced to enable the column sidelines to coincide with the peripheral outline of the reinforcing steel bar line, and the longitudinal reinforcing steel bar can be ensured to be intersected with the column sidelines.
Step A2: and extending each column side line forming the closed area, and dividing the closed area into a plurality of small graphs according to the extension lines.
Step A3: the line segments that make up each small figure outline are numbered in order. Generally, the line segments can be ordered from left to right according to the line segments parallel to the abscissa, and then from bottom to top according to the line segments parallel to the ordinate, and the line segments can be numbered. For example, a closed region composed of the pillar borders as shown in fig. 12 is divided and numbered according to the above steps, and the schematic diagram is shown in fig. 13.
Step A4: and identifying the label of the longitudinal bar from the label, judging the serial number of the line segment intersected with the longitudinal bar according to the information of the label, and calculating the position information of the intersection point of the longitudinal bar on the line segment. If the marking lines exist in the processing area to wrap the longitudinal ribs and the corresponding marking information is in the form of the longitudinal ribs, the marks are judged as the marks of the longitudinal ribs, the numbers corresponding to the line segments of the intersection of the longitudinal ribs and the column side lines are calculated according to the acquired marking information data of the longitudinal ribs, and the longitudinal ribs are drawn at the positions of the line segments corresponding to the numbers. Fig. 14 is a schematic view showing the longitudinal rib position calculated based on fig. 13.
Step S106, calculating stirrups and lacing wires in the processing area according to the longitudinal bar positions, wherein the specific mode is as follows:
and identifying the stirrup marks from the marks, confirming the longitudinal bars intersected with the stirrups according to the marked information, calculating the stirrup position information formed by the intersected longitudinal bars, and calculating the stirrup initial characteristic line position information. If the marking line is intersected with the stirrup and the corresponding marking information is in the form of the stirrup, the marking information corresponding to the marking line is the stirrup data. And according to the obtained stirrup marking information, giving data to the corresponding stirrups, determining longitudinal reinforcements intersected with the stirrup graphs, drawing the closed stirrup graphs around the longitudinal reinforcements, and simultaneously selecting one angle to draw the initial characteristic line of the stirrups. If the detailed reinforcing steel bar shape graph is intersected with the marking line and the marking information is in a reinforcing steel bar format, the reinforcing steel bar information of the in-situ reinforcing steel bar and the corresponding reinforcing steel bar graph is in-situ reinforcing steel bar information. The marked information is subsequently used for comparing with the steel bar big sample drawing, and the steel bar with data on the steel bar shape detailed drawing is assigned to the steel bar on the position corresponding to the steel bar big sample drawing.
Similarly, a lacing wire mark is identified from the mark, a longitudinal rib intersected with the lacing wire is confirmed according to the marked information, lacing wire position information formed by surrounding the intersected longitudinal rib is calculated, and lacing wire initial characteristic line position information is calculated. If a marking line is intersected with the lacing wire and the corresponding marking information is in the form of the lacing wire, the marking information corresponding to the marking line is the lacing wire data. And according to the acquired lacing wire labeling information, giving data to corresponding lacing wires, determining longitudinal ribs intersected with the lacing wire graph, selecting one side of each longitudinal rib to draw the lacing wire graph, and simultaneously drawing lacing wire initial characteristic lines at two ends of each lacing wire. Fig. 15 is a schematic diagram of the processing area after calculating the stirrups and the tie bars based on fig. 14, wherein two tie bar patterns and two stirrup patterns are included.
And S107, storing the column macro sample data in all the processing areas. After all processing areas are processed in the same way, accurate column large sample data can be obtained, and the column large sample data can be used for generating accurate design drawings, calculating the consumption of reinforcing steel bars or calculating the manufacturing cost and the like after being stored.
The technical scheme of this application, through dividing the design drawing into a plurality of pending territories, the reinforcing bar line to in every processing area discerns and distinguishes stirrup and lacing wire, the positional information who indulges the muscle is indulged in the accurate location of the reunion mark information, the accurate position of stirrup and lacing wire is recalculated on the basis of indulging the muscle position, it is not accurate to solve the building drawing well sketch map of artifical drawing fast high-efficiently through automatic means, can't be used for normal construction, the problem that statistics of materials and cost calculated.
