The following provides a detailed description of the method, apparatus, computer-readable medium, and electronic device for reviewing architectural drawings in accordance with the present application.
Referring to fig. 1, fig. 1 schematically shows a flowchart of steps of a drawing examination method for providing a construction drawing according to an embodiment of the present application. The map reviewing method of the construction drawing mainly includes the following steps S101 to S105.
And S101, obtaining a building drawing to be checked.
The construction drawing to be checked draws a plurality of construction components and name information for marking the construction components on the drawing content.
Specifically, the architectural drawing to be checked is a drawing manufactured according to a standard specification, and a tab bar in the drawing manufactured according to the standard specification generally includes the following information: picture name, specialty, sub-project name, picture number (e.g., picture name: XX plan/elevation), specialty: building/structure (or picture type: construction/construction), sub-project name: XX building, project name: XX project, picture number: 03). In the architectural drawing, the bottom edge of the drawing frame is parallel to the X axis or the Y axis of the drawing view coordinate system; the layer name should accurately express the content of the layer, the same layer should not contain multiple types of components, and the chart primitives should not be placed in the layer 0; the chart elements are arranged on the printable layer (the content of the closed, frozen and unprintable layer is not examined); the architectural base map of the electromechanical and structural needs to keep the map-layer information of the original architectural drawing.
Optionally, the building drawing to be checked may be a building drawing in a CAD drawing format, and if the building drawing to be checked is a building drawing in a non-CAD drawing format, the building drawing in the non-CAD drawing format is converted into the building drawing in the CAD drawing format. For example, if the construction drawing to be checked is a drawing in other formats such as PDF, the construction drawing needs to be converted into a CAD drawing format for further processing.
And S102, identifying a building component in the building drawing to be checked, wherein the building component comprises a plurality of part structures forming the building drawing.
After obtaining the building drawing to be checked, identifying a plurality of building components in the building drawing to obtain the position coordinate information and the category information of the building components.
Step S103, vectorizing the position coordinates corresponding to the building components to form matrix coordinates.
After the building components in the construction drawing to be checked are identified, the position coordinates of each building component can be obtained, and then the position coordinates are segmented according to categories and assembled into vectors, so that subsequent calculation is facilitated.
And step S104, performing parallel operation on the matrix coordinates of the corresponding building components according to the logic relationship between the preset objects.
The logic relation between the objects is preset, the logic relation between the objects represents a regular relation which needs to be met between the building components, and then the calculation is carried out in a parallel calculation mode.
And S105, transmitting the parallel operation result into an interface position corresponding to a preset logic rule function, and performing rule calculation to generate a diagram examination result, wherein the diagram examination result is used for indicating whether the building component meets the diagram examination rule.
After calculation, returning data combined with the coordinate points, transmitting the coordinate point set into a corresponding interface position of a preset logic rule function, obtaining an image examination result according to the logic rule function, and determining whether the building component conforms to the building rule.
According to the technical scheme provided by the embodiment of the application, the position coordinates corresponding to the building components in the building drawing to be checked are vectorized, and then parallel operation is performed according to the logic relation between the preset objects, so that the calculation efficiency of the matrix is increased, and the efficiency of checking the drawing is improved when whether the building drawing accords with the preset rule or not is judged.
Optionally, a currently common building rule calculation acceleration algorithm based on a divide-and-conquer algorithm often adopts a simple divide-and-conquer strategy. Each n x n matrix can be divided into four n/2x n/2 matrices: therefore, formula C can be rewritten as:
the above equation is then equivalent to the following four equations:
C11＝A11·B11+A12·B21；
C12＝A11·B12+A12·B22；
C21＝A21·B11+A22·B21；
C22＝A21·B12+A22·B22；
therefore, each formula needs to calculate two matrix multiplications and one matrix addition, and t (n) is used to represent the time complexity of n × n matrix multiplication, so we can obtain a recursion formula according to the above decomposition.
T(n)＝8T(n/2)+Θ(n2)
Where 8T (n/2) represents 8 matrix multiplications and the matrix size of the multiplication is reduced to n/2. Θ (n2) represents the temporal complexity of 4 matrix additions and the temporal complexity of the merged C matrix.
Where 8T (n/2) represents 8 matrix multiplications and the matrix size of the multiplication is reduced to n/2. Θ (n2) represents the temporal complexity of 4 matrix additions and the temporal complexity of the merged C matrix.
To calculate t (n), t (n) ═ Θ (n3) can be calculated by drawing a recursive tree or by direct calculation using the "main method" without complexity.
It can be seen that the simple divide-and-conquer strategy does not have the effect of accelerating the operation. Because the decomposed problem includes 8 matrix multiplications and 4 matrix additions, that is, the 8 matrix multiplications result in the speed not being increased.
In order to solve the problem of low matrix multiplication efficiency, the method adopts a divide-and-conquer algorithm, and one matrix multiplication operation reduces the time complexity. Specifically, each matrix is divided into 4, and then 10 intermediate matrices are created as follows:
S1＝B12-B22；S2＝A11+A12；S3＝A21+A22；S4＝B21-B11；S5＝A11+A22；S6＝B11+B22；S7＝A12-A22；S8＝B21+B22；S9＝A11-A21；S10＝B11+B12；
next, 7 matrix multiplications were calculated:
P1＝A11.S1；P2＝S2.B22；P3＝S3.B11；P4＝A22.S4；P5＝S5.S6；P6＝S7.S8；P7＝S9.S10；
finally, from these 7 results, the C matrix can be calculated,
C11＝P5+P4-P2+P6；C12＝P1+P2；
C21＝P3+P4；C22＝P5+P1-P3-P7；
therefore, 8 times of matrix multiplication is performed before improvement, 7 times of matrix multiplication is performed after improvement, and one matrix multiplication is ingeniously omitted in the improved matrix calculation, so that the time complexity is reduced, and the algorithm efficiency is improved by the building rule calculation acceleration algorithm based on the divide-and-conquer algorithm.
In one embodiment of the present application, referring to fig. 2, fig. 2 schematically illustrates a flow of steps for identifying a building element in a construction drawing to be checked in an embodiment of the present application. The method for identifying the building component in the construction drawing to be checked mainly comprises the following steps S201 to S204.
Step S201, obtaining image information in the architectural drawings to be checked.
The image information includes other information such as points and lines.
Step S202, splitting the image information to obtain at least one rectangular frame.
The method comprises the steps of splitting image information to obtain a plurality of points and a plurality of line segments, obtaining a plurality of connecting nodes according to the plurality of points and the plurality of line segments, and carrying out closed-loop division on the connecting nodes to obtain at least one rectangular frame.
Optionally, after the connection nodes are divided into closed loops, whether repeated line segments or repeated points exist needs to be detected; if the repeated line segments and the repeated points exist, checking whether repeated connection nodes exist, if so, extracting at least two rectangular frames corresponding to the repeated connection nodes for space analysis, determining whether the at least two rectangular frames are rectangular frames which accord with the space and have rationality, if so, keeping, and otherwise, marking the at least two rectangular frames.
Step S203, obtaining the coordinates of each vertex of at least one rectangular frame.
Wherein, the coordinate of each vertex can be obtained by a space rectangular coordinate system.
And step S204, identifying the building component corresponding to each rectangular frame according to the coordinates of each vertex of at least one rectangular frame.
Like this, through split point and line segment, split the CAD picture, and then the comparatively accurate rectangle frame that obtains a plurality of components in the drawing promotes the intelligence and the accuracy of building drawing component discernment.
Taking the YOLOv5 model as an example, YOLOv5 is a single-stage target detection algorithm that will perform target detection of building element graphics by deploying the YOLOv5 model. The input end of the YOLOv5 model inputs the building element graph. Since the input image size of the model is 608 × 608, the building element image is converted into a predetermined input format (e.g., 608 × 608), and the stage generally includes an image preprocessing stage, i.e., scaling the input image to the predetermined input size of the model, and performing normalization. Further, the input end of YOLOv5 adopts a Mosaic data enhancement mode, adopts adaptive anchor frame calculation and adaptive image adjustment, and divides the input image with the size not meeting the requirement into 608 × 608, and if the input image is smaller than 608 × 608, filling is needed to make the input image meet the preset input format. Therefore, the building element image is subject to target detection through the YOLOv5 model, and the building element graph in the building element image can be obtained.
In one embodiment of the present application, referring to fig. 3, fig. 3 schematically illustrates a flow of steps for identifying a building element in a construction drawing to be audited in another embodiment of the present application. The method for identifying the building component in the construction drawing to be audited mainly comprises the following steps S301 to S303.
And S301, acquiring character information in the construction drawing to be checked.
The text can be found and identified in the building drawing by the character identification technology, namely, the position of the name information of the building component in the building drawing is found facing to the building component drawn on the building image, and then the text in the position is identified to obtain the name information of the building component, and finally the building component image and the image coordinate corresponding to the name information are obtained.
The Character Recognition technology may be an OCR (Optical Character Recognition) technology, which converts text attached to the architectural drawing into image information by an Optical input method such as scanning, and then converts the image information into a computer input technology that can be used.
Step S302, determining the category of each building component according to the character information;
step S303, contour fitting is performed on the building element, and the spatial range of the building element is determined.
Specifically, the contour of the building element graph in the building element image can be obtained through a contour detection algorithm, and the element geometric graph coordinates are obtained based on the contour and the image coordinates of the building element graph.
In this way, more accurate information of the building element can be obtained by the contour detection algorithm.
In one embodiment of the present application, referring to fig. 4, fig. 4 schematically shows a flow of steps for determining a spatial extent of a building element by contour fitting the building element in another embodiment of the present application. The contour fitting of the building element to determine the spatial extent of the building element may mainly further comprise the following steps S401 to S402.
Step S401, extracting the edge contour of the wall;
step S402, carrying out polygon fitting processing based on the edge outline, and obtaining a processed wall body outline from the fitted polygon so as to obtain the space range of the building component.
Specifically, the polygon fitting of the contour is performed by using an iterative endpoint fitting method, and in the fitting algorithm, the more the iteration times, the higher the fitting accuracy of the contour, and the closer the fitted contour line is to the original contour line. In general, the main steps of the fitting algorithm to fit a profile are as follows:
(1) setting a distance threshold T;
(2) selecting a starting point A and an end point B of a contour line as two end points of a fitting polygon;
