Detailed Description
In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
The most key concept of the invention is as follows: by identifying the axis symbols in the two-dimensional drawing, the coordinate range of each drawing is determined according to the axis symbols.
Referring to fig. 1 to 2, a method for generating an axis according to a marked line includes the steps of:
s1, identifying an axis symbol in the two-dimensional drawing;
and S2, determining the coordinate range of each graph according to the axis characters.
The axis on the construction drawing refers to the position base line of important components such as main wall columns, beam frames and the like, the distance in the transverse direction is called 'bay', the longitudinal distance is called 'depth', and the coordinates of the left lower corner on the drawing are taken as starting points. The symbol used to denote the axis is simply called the axis network.
From the above description, the beneficial effects of the present invention are: the coordinate range of each drawing is determined according to the axis symbol by identifying the axis symbol in the two-dimensional drawing, so that the automatic segmentation of the drawing is realized; compared with other lines, the axis symbol has obvious characteristics and high identification degree, so that the identification efficiency and accuracy are high in the drawing segmentation process; meanwhile, the axis symbol is positioned at the edge position of each graph, so that the coordinate range of each graph is defined, simplicity and effectiveness are realized, the segmentation efficiency is high, and the accuracy is high; in addition, the shaft symbol can also be used for judging the axis and the mark line, so that the building component is judged through the axis, and convenience is provided for subsequent rollover.
Further, the step S1 is specifically: identifying all circles in the two-dimensional drawing, judging whether English characters or Arabic characters exist in the circles, and if yes, determining the circles containing the English characters or the Arabic characters as axis characters.
Wherein, the main components of the axis symbol include a circle and a number. When the shaft symbol is used for representing the transverse plane positioning track, namely the transverse shaft symbol, the inner part of the transverse shaft symbol comprises Arabic characters such as 1, 2, 3 … and the like, and when the shaft symbol is used for representing the longitudinal plane positioning track, namely the longitudinal shaft symbol, the inner part of the longitudinal shaft symbol comprises capital English characters such as A, B, C … and the like.
As can be seen from the above description, by judging the axis characters by the circle and the number, all the axis characters can be determined quickly and efficiently.
Further, the step S2 is specifically:
s21, identifying all axes according to the shaft signs, and if no axis is identified according to the shaft signs, executing the step S22;
s22, identifying all marking lines according to the shaft marks, and generating axes according to the marking lines;
s23, forming an axle network by the axes with the intersection relation, and determining the coordinate range of each axle network;
and S24, expanding the coordinate range of each axis net outwards by a first value to obtain the coordinate range of each graph, wherein the first value is any one value in the range of [500 mm, 3000 mm ].
In the two-dimensional drawing of the building engineering, the axis mainly plays a role in positioning. For the structural drawing, the basic drawings all have axes; for architectural drawings, there is no axis in the basic drawings.
As can be seen from the above description, after the axis identifier is determined, in order to further identify the building component and more clearly define the coordinate range of each graph, the axis in the graph needs to be identified, for the graph with the axis, the axis is identified by the axis identifier, and for the graph without the axis, the above technical solution generates the axis by marking the line, thereby facilitating the subsequent component identification and more clearly defining the coordinate range of each graph.
Further, in the step S21, all the axes identified according to the shaft identifier are specifically:
s211, taking each axis symbol as a circle center and taking any numerical value in (0,1000 mm) as a radius to obtain a guide line screening range, and putting all line segments intersected with the guide line screening range into a guide line set to be confirmed;
s212, selecting a line segment from the guidance line set to be confirmed as a first line segment, and judging whether the first line segment is the only line segment intersected with the corresponding first axis symbol, if so, the first line segment is the first axis symbol guidance line, otherwise, continuously selecting a line segment from the guidance line set to be confirmed for judgment until the first axis symbol guidance line is obtained;
s213, marking all line segments which are positioned in the same layer with the first axis index line and at least are parallel to any line segment positioned in the same layer as the first axis index line as axis index lines from the index line set to be confirmed;
s214, sequentially executing the step S212 and the step S213 on other line segments which are not in the same layer with the first axis index line in the index line set to be confirmed or are not parallel to all line segments of the index line set to be confirmed until all the line segments of the index line set to be confirmed are judged, and obtaining an axis index line set;
and S215, marking a line segment which is collinear with any one of the axis index lines in the axis index line set as an axis.
The axis indicator line is a line extending along the axis indicator line, and the axis indicator line are normally connected directly, but may not be directly connected to each other.
From the above description, the axis symbol needs to be expanded by a certain range to screen out the axis symbol guiding line, so as to avoid omission; judging one of the intersecting line segments, wherein the judgment condition is that the layer is structured, and the intersecting line segment can be ensured to belong to an axis indicator lead line; by judging one of the intersecting line segments and directly determining other line segments through the same layer and the parallel relation, the recognition efficiency can be improved; and other intersecting line segments which are not in the same layer or are not parallel to all the line segments are judged, so that omission is avoided.
Further, the step S22 is specifically:
s221, each axis symbol takes the axis symbol as a circle center, takes any numerical value in (0,1000 mm) as a radius, obtains a marking line screening range, marks all line segments which are intersected with the marking line screening range and have Arabic characters on two vertical sides in the line segment direction as marking lines, obtains a marking line set, and records the corresponding relation between the marking lines and the axis symbols;
s222, finding out a first marking line with the longest length from marking lines corresponding to each axis symbol, finding out a second marking line with the longest length from all the first marking lines, and connecting the axis symbols with the same first marking line in series to obtain axis symbol lines in the same row;
and S223, taking a point on the first marking line, which is perpendicular to the corresponding axis symbol, as a starting point, extending an auxiliary line segment towards a direction which is perpendicular to the direction of the same row of axis symbol lines where the corresponding axis symbol is located and is far away from the corresponding axis symbol, wherein the auxiliary line segment is terminated when encountering other auxiliary line segments extending from other first marking lines, and the length of the auxiliary line segment is less than or equal to that of the second marking line.
The corresponding axis symbol is the corresponding relationship between the annotation line and the axis symbol recorded in step S221, that is, for each first annotation line, there may be a plurality of corresponding axis symbols, and the plurality of corresponding axis symbols all need to extend the auxiliary line segment. Meanwhile, the first mark line with the longest length is formed by connecting the axis symbols at the head end and the tail end of the same-row axis symbol line, namely, all the axis symbols on the same-row axis symbol line need to extend out of the auxiliary line segment along the direction which is perpendicular to the first mark line and far away from the first mark line, and at the moment, the auxiliary line segment is the line segment extending out of each axis symbol, namely the axis.
From the above description, the axes are determined by the marked lines, and the marked line with the longest length ensures that all the axis symbols can extend out of the axes corresponding to the axis symbols, so that the axes can be generated by the marked lines on the non-axis graph to form the axle network; the length of the auxiliary line segment is limited to avoid the auxiliary line segment extending into other figures.
Further, the step S24 is specifically:
adding a first value to the maximum abscissa of each axle network to obtain an upper limit abscissa, subtracting the first value from the minimum abscissa of each axle network to obtain a lower limit abscissa, and adding the first value to the maximum ordinate of each axle network to obtain an upper limit ordinate; and subtracting the first value from the minimum ordinate of each axle network to obtain a lower limit ordinate, wherein the coordinate range of each graph comprises an upper limit abscissa, a lower limit abscissa, an upper limit ordinate and a lower limit ordinate of the corresponding axle network.
From the above description, the coordinate range of the graph is defined by expanding a certain range through the axis network, so as to ensure the integrity of each graph which is divided.
Further, the step S2 is followed by:
s3, screening all characters in the coordinate range of each graph, judging whether one to two lines are arranged below the characters and whether the characters contain preset type names, marking the characters which are provided with one to two lines and contain the preset type names as graph names, and recording the corresponding relation between the coordinate range of each graph and the graph names.
Among them, preset type names such as floor information and building member information, etc.
From the above description, it can be determined by presetting the type name and two features of one to two lines, and recording the corresponding relationship between the coordinate range of each graph and the graph name, so as to facilitate the subsequent modeling.
Further, the step S3 is followed by:
and S4, extracting the floor information from the graph name, and importing the coordinate range, the graph name, the floor information and the component type comprising the axis symbol of each graph into a tree control and XML for storage and display.
As can be seen from the above description, the drawing division of the present invention means that the coordinate range and the corresponding information of each drawing are determined on software, that is, a whole two-dimensional drawing is divided into independent drawings on software, and the drawings correspond to each other through information such as the names, the floor information, and the axis symbols, so as to facilitate the subsequent modeling.
As shown in fig. 3, an electronic device comprises a memory, a processor and a computer program stored on the memory and executable on the processor, the processor implementing the steps of the above-mentioned method for generating an axis from a marked line when executing the computer program.
From the above description, the beneficial effects of the present invention are: the coordinate range of each drawing is determined according to the axis symbol by identifying the axis symbol in the two-dimensional drawing, so that the automatic segmentation of the drawing is realized; compared with other lines, the axis symbol has obvious characteristics and high identification degree, so that the identification efficiency and accuracy are high in the drawing segmentation process; meanwhile, the axis symbol is positioned at the edge position of each graph, so that the coordinate range of each graph is defined, simplicity and effectiveness are realized, the segmentation efficiency is high, and the accuracy is high; in addition, the shaft symbol can also be used for judging the axis and the mark line, so that the building component is judged through the axis, and convenience is provided for subsequent rollover.
