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, the present invention is a flow chart of steps of a method for identifying stirrups and tie bars, 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).
The technical scheme of this application through dividing the design drawing into a plurality of pending districts, discerns to the reinforcing bar line in every processing area and distinguishes stirrup and lacing wire, and the building drawing that solves artifical drawing is not accurate in the sketch map through automatic means high efficiency, can't be used for the problem that normal construction, material statistics and cost calculated.
