Description

Technical Field

[0001] The present invention relates to the technical field of architectural drawing or other related fields. Specifically, it relates to a method and device for drawing a simplified steel bar diagram with segmented scaling, and an electronic device. Background Art

[0002] In the fields of building construction and civil engineering, reinforced concrete structures have become an indispensable part of modern buildings due to their excellent load-bearing capacity and durability. With the increasing complexity of engineering design, the layout and shape of steel bars have become increasingly diversified. From simple straight lines to complex curve combinations, the types and shapes of steel bars show great diversity. Against this background, the simplified steel bar diagram, as an important part of construction drawings, plays a crucial role in the rapid understanding and construction of construction workers. The simplified steel bar diagram needs to maintain the main shape characteristics of the steel bar while facilitating the positioning and installation of the steel bar by construction workers through simplified graphic expressions. Therefore, the accurate drawing and efficient output of the simplified steel bar diagram have become a key link in the automated processing of construction drawings.

[0003] In the related art, the existing strategies for drawing simplified steel bar diagrams have limitations in dealing with complex steel bar shapes. The existing strategies for drawing simplified steel bar diagrams rely on a preset steel bar shape library, and their automated drawing ability is limited for non-standard or free-form steel bar graphics. In addition, the existing strategies for drawing simplified steel bar diagrams usually require users to manually draw the shape of the simplified steel bar, or can only convert and output the simplified steel bar diagram of the preset shape. This drawing method is not only inefficient but also prone to human errors. Especially when dealing with complex steel bar graphics including straight line segments and arc segments, the existing strategies for drawing simplified steel bar diagrams are difficult to achieve the fine and beautiful degree of manual drawing, and at the same time, they cannot maximize the use of the space of the drawing cell, affecting the clear transmission of information and the overall layout of the drawing. Therefore, the existing strategies for drawing simplified steel bar diagrams are difficult to provide an efficient, accurate, and automated solution for drawing simplified diagrams when facing non-standardized and complex steel bar graphics.

[0036] The present invention will be described in detail below in conjunction with each embodiment.

[0037] Embodiment 1

[0038] According to an embodiment of the present invention, an embodiment of a method for drawing a segmented scaled steel bar sketch is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0039] Figure 1 FIG. is a flowchart of an optional method for drawing a segmented scaled steel bar sketch according to an embodiment of the present invention, as Figure 1 shown, the method includes the following steps:

[0040] Step S101, rotate the steel bar graph, determine the target rectangular bounding box based on the coordinates of each turning point in the rotated steel bar graph, and calculate the set of scale factors of the target rectangular bounding box and the target cell on the x-axis and y-axis of the coordinate system based on the side lengths of the target rectangular bounding box and the target cell on the x-axis and y-axis of the coordinate system.

[0041] In the embodiment of the present invention, two schemes for rotating the steel bar graph are provided. The first is the case with a symmetry axis, and the second is the case without a symmetry axis. The following will be described in combination with different embodiments respectively.

[0042] First, in the case of having a symmetry axis, how to rotate the steel bar graph.

[0043] Optionally, the step of rotating the steel bar graph includes: in the case where one or more symmetry axes of the steel bar graph are detected, comparing the side lengths of the target cell on the x-axis and y-axis of the coordinate system; in the case where the side length on the x-axis is greater than the side length on the y-axis, determining the shortest symmetry axis among the multiple symmetry axes as the target symmetry axis; in the case where the side length on the x-axis is not greater than the side length on the y-axis, determining the longest symmetry axis among the multiple symmetry axes as the target symmetry axis; rotating the steel bar graph so that the target symmetry axis is parallel to the y-axis of the coordinate system.

[0044] In the case where a symmetry axis already exists in the detected steel bar graph, first determine an optimal target symmetry axis. When determining the target symmetry axis, first detect one or more symmetry axes existing in the steel bar graph, then compare the side lengths of the target cell on the x-axis and y-axis of the coordinate system, and determine the target symmetry axis according to the comparison result.

[0045] When the side length of the target cell on the x-axis of the coordinate system is greater than the side length on the y-axis, the shortest axis of symmetry among multiple axes of symmetry is determined as the target axis of symmetry; when the side length of the target cell on the x-axis of the coordinate system is not greater than the side length on the y-axis, the longest axis of symmetry among multiple axes of symmetry is determined as the target axis of symmetry. After determining the target axis of symmetry, the steel bar pattern is rotated so that the target axis of symmetry is parallel to the y-axis of the coordinate system. By determining the target axis of symmetry in this way and then rotating the steel bar pattern, the resulting steel bar sketch can be made more beautiful.

[0046] Second, in the case of no axis of symmetry, how to rotate the steel bar pattern.

[0047] Optionally, the step of rotating the steel bar pattern further includes: when it is detected that the steel bar pattern has no axis of symmetry, obtaining all the arc edges of the steel bar pattern, and for each arc edge, connecting the starting point and the ending point of the arc edge to obtain a transformed arc edge; obtaining all the straight edges of the steel bar pattern; determining the longest edge among all the transformed arc edges and all the straight edges as the target axis; rotating the steel bar pattern so that the target axis is parallel to the coordinate axis where the long side of the target cell is located, where the long side of the target cell is the side with the longest length after comparing the x-axis length and the y-axis length of the target cell.

[0048] When it is detected that the steel bar pattern has no axis of symmetry, the embodiment of the present invention adopts a flexible strategy to ensure that even in an asymmetric steel bar pattern, a clear reference axis can be found for subsequent scaling and drawing operations. The core of this strategy lies in analyzing the arc edges and straight edges in the steel bar pattern, constructing a "target axis" that can best reflect the structural characteristics of the steel bar, and performing rotation and adjustment accordingly to achieve the best graphic adaptation and visual presentation.

[0049] First, for each arc edge in the steel bar pattern, the embodiment of the present invention transforms the arc edge into a straight edge (i.e., a transformed arc edge) by connecting its starting point and ending point. The purpose of this transformation is to simplify the complex curve features into straight line segments that are easy to process, so that the steel bar pattern can be scaled and drawn through a unified processing flow.

[0050] Next, the embodiment of the present invention comprehensively considers all the transformed arc edges (existing in the form of straight edges, called "transformed arc edges") and all the straight edges originally existing in the steel bar pattern. The longest edge among these transformed arc edges and straight edges is determined and designated as the "target axis". The longest straight edge usually can represent the main direction or structural characteristics of the steel bar pattern. Selecting it as the target axis can ensure that subsequent rotation and scaling operations are more accurate. At the same time, it can also make the best use of the available space of the target cell to draw a steel bar sketch that is both beautiful and rich in information.

[0051] After determining the target axis, in the embodiments of the present invention, the steel bar pattern is rotated. It should be noted that here the target axis is made parallel to the coordinate axis where the short side of the target cell is located. Here, if the target cell is vertical and the length of the x-axis < the length of the y-axis, then the target axis should be rotated to be parallel to the x-axis. If the target cell is horizontal and the length of the x-axis > the length of the y-axis, then the target axis should be rotated to be parallel to the y-axis. After that, operations such as determining the target rectangular bounding box can be carried out.

[0052] In the embodiments of the present invention, first, a coordinate system is determined based on the target cell. The target cell refers to the area where the final drawn steel bar sketch is placed, which can be a cell in an Excel table. The determined coordinate system is usually located at the lower left corner of the target cell. The x-axis is along the long side direction of the target cell, and the y-axis is along the short side direction of the target cell, forming a two-dimensional rectangular coordinate system that matches the geometric characteristics of the target cell.

[0053] Next, by analyzing the geometric characteristics of the steel bar pattern to identify its symmetry, the axis of symmetry of the steel bar pattern, that is, the target axis of symmetry, is determined. Then, the steel bar pattern is rotated so that the target axis of symmetry of the steel bar pattern is parallel to the x-axis of the coordinate system.

[0054] When the steel bar pattern is adjusted to the aligned state with the coordinate system of the target cell through rotation operations, the next key step is to determine an accurate target rectangular bounding box to ensure that each steel bar segment of the steel bar pattern can be properly included in the target cell in subsequent scaling processing.

[0055] The determination of the target rectangular bounding box is based on the coordinate information of each turning point in the steel bar pattern. Figure 2 It is a schematic diagram of an optional steel bar pattern according to the embodiments of the present invention, as Figure 2 shown. The turning points of this steel bar pattern include: two vertices of the four arc corners and two vertices of the two inclined straight lines.

[0056] By determining the x-axis coordinates and y-axis coordinates of all turning points, the minimum values of the x-axis coordinates and y-axis coordinates are respectively taken as the lower left corner point PointMinXY(Xmin, Ymin) of the target rectangular bounding box, and the maximum values of the x-axis coordinates and y-axis coordinates are respectively taken as the upper right corner point PointMaxXY(Xmax, Ymax) of the target rectangular bounding box. The target rectangular bounding box is constructed through the lower left corner point and the upper right corner point. Figure 3 It is a schematic diagram of an optional target rectangular bounding box according to the embodiments of the present invention, as Figure 3 shown. The bold rectangle is Figure 2The target rectangular bounding box corresponding to the shown rebar graphic. RebarW refers to the side length of the target rectangular bounding box on the y-axis, and RebarL refers to the side length of the target rectangular bounding box on the x-axis.

[0057] To ensure that the rebar graphic can be accurately scaled and drawn within the target cell, the embodiments of the present invention further analyze the relative size relationship between the target rectangular bounding box and the target cell. Since the length and width dimensions of the target cell are known, and the rebar sketch needs to be drawn within the area defined by the length and width, therefore, by comparing the side lengths of the target rectangular bounding box and the target cell on the x-axis and y-axis, two sets of scale factors can be calculated: one set is the scale factor of the width of the target rectangular bounding box to the width of the target cell (denoted as RatioX), and the other set is the scale factor of the height of the target rectangular bounding box to the height of the target cell (denoted as RatioY). These two sets of scale factors form a set of scale factors, which are the key parameters for realizing the scaling of the rebar graphic.

[0058] Step S102, traverse all rebar segments of the rebar graphic, determine the angles between the rebar segments and the x-axis and y-axis, select the target scale factor from the set of scale factors based on the angles, and scale the rebar segments based on the target scale factor.

[0059] After obtaining the set of scale factors, next, each rebar segment in the rebar graphic is accurately scaled to ensure that it can be drawn beautifully and accurately within the target cell.

[0060] The embodiments of the present invention will traverse all rebar segments in the entire rebar graphic. For each straight segment or arc segment after straightening processing, through the coordinate information of the starting point and ending point of the rebar segment, the angles between the rebar segment and the x-axis and y-axis can be calculated. Figure 4 It is a schematic diagram of an optional rebar segment angle according to an embodiment of the present invention. For an inclined straight segment in the rebar graphic, its angle with the y-axis is Ay, and its angle with the x-axis is Ax.

[0061] Based on the obtained angles, the embodiments of the present invention select the most appropriate scaling ratio from the previously constructed set of scale factors. That is, for each rebar segment, if its angle with the x-axis is less than its angle with the y-axis, then RatioX is selected as the target scale factor; conversely, if its angle with the y-axis is smaller, then RatioY is selected as the target scale factor. The purpose of this strategy is to ensure that during the scaling process, the rebar segment can be scaled as much as possible along its main direction (i.e., the direction with a smaller angle with the coordinate axes), so as to maximize the display of the shape characteristics of the rebar graphic within the limited cell size.

[0062] Finally, after selecting the target scale factor, the embodiment of the present invention performs a scaling process on the selected steel bar segments. This scaling operation is synchronized and in the same proportion on the x-axis and y-axis to ensure that the scaled steel bar segments still maintain their original shape ratio.

[0063] Step S103: Based on all the scaled steel bar segments, determine the simplified steel bar diagram of the steel bar pattern.

[0064] When the precise scaling process of all the steel bar segments in the steel bar pattern is completed, integrate all the scaled steel bar segments to form the final simplified steel bar diagram of the steel bar pattern. This process is to splice the scaled steel bar segments based on the head-to-tail connection order of the steel bar segments in the steel bar pattern to obtain the simplified steel bar diagram of the steel bar pattern. Figure 5 It is a schematic diagram of an optional simplified steel bar diagram according to an embodiment of the present invention, as Figure 5 shown. The thickened rectangle on the periphery is the target cell. CellL is the width of the target cell, CellW is the height of the target cell. Inside is the simplified steel bar diagram, and the numbers 2900, 1024, and 659 are the actual lengths of the steel bar pattern.

[0065] Optionally, the step of calculating the set of scale factors of the target rectangular bounding box and the target cell on the x-axis and y-axis includes: determining the x-axis coordinate and y-axis coordinate of each turning point in the rotated steel bar pattern; based on the minimum x-axis coordinate, minimum y-axis coordinate, maximum x-axis coordinate, and maximum y-axis coordinate among all the turning point coordinates, determining the target rectangular bounding box; calculating the side lengths of the target rectangular bounding box on the x-axis and y-axis, and obtaining the side lengths of the target cell on the x-axis and y-axis; based on the side lengths of the target rectangular bounding box and the target cell on the x-axis, determining the first type of scale factor of the target rectangular bounding box and the target cell on the x-axis; based on the side lengths of the target rectangular bounding box and the target cell on the y-axis, determining the second type of scale factor of the target rectangular bounding box and the target cell on the y-axis; integrating the first type of scale factor and the second type of scale factor to obtain the set of scale factors.

[0066] When calculating the set of scale factors of the target rectangular bounding box and the target cell on the x-axis and y-axis, first, based on the coordinate system, the embodiments of the present invention perform detailed coordinate point capture on the rotated steel bar graph to determine the exact coordinate values of each turning point on the x-axis and y-axis. Next, find the minimum x-axis coordinate, the minimum y-axis coordinate, the maximum x-axis coordinate, and the maximum y-axis coordinate among all the turning point coordinates. These four coordinate values define the outer boundary of the steel bar graph in the coordinate system. Take the minimum values of the x-axis coordinate and the y-axis coordinate as the lower left corner point PointMinXY(Xmin, Ymin) of the target rectangular bounding box, and take the maximum values of the x-axis coordinate and the y-axis coordinate as the upper right corner point PointMaxXY(Xmax, Ymax) of the target rectangular bounding box, and construct the target rectangular bounding box through the lower left corner point and the upper right corner point.

[0067] After determining the target rectangular bounding box, further calculate the side lengths of the target rectangular bounding box on the x-axis and y-axis. The calculation of the side lengths is directly based on the above four coordinate values and is obtained by the difference between the maximum coordinate value and the minimum coordinate value.

[0068] Then obtain the side lengths of the target cell on the x-axis and y-axis. These side lengths define the size of the target cell, that is, the drawing area available in the sketch drawing. By comparing the side lengths of the target rectangular bounding box and the side lengths of the target cell, the scale factors on the x-axis and y-axis can be calculated respectively. Specifically, the first type of scale factor (the scale factor on the x-axis) is obtained by calculating the ratio of the width of the target cell to the width of the target rectangular bounding box, and the formula is: RatioX = width of the target cell / width of the target rectangular bounding box. The second type of scale factor (the scale factor on the y-axis) is obtained by calculating the ratio of the height of the target cell to the height of the target rectangular bounding box, and the formula is: RatioY = height of the target cell / height of the target rectangular bounding box. Finally, by synthesizing the first type of scale factor and the second type of scale factor, the set of scale factors is obtained.

[0069] Optionally, the steps of traversing all the steel bar segments of the steel bar graph and determining the angles between the steel bar segments and the x-axis and y-axis include: in the case where the steel bar segment is a straight steel bar segment, determining the angles between the straight steel bar segment and the x-axis and y-axis; in the case where the steel bar segment is an arc steel bar segment, for each arc steel bar segment, connect the starting point and the ending point of the arc steel bar segment to obtain a transformed straight steel bar segment, determine the angles between the transformed straight steel bar segment and the x-axis and y-axis, and determine the angles between the arc steel bar segment and the x-axis and y-axis as the angles between the transformed straight steel bar segment and the x-axis and y-axis.

[0070] When traversing all the steel bar segments of the steel bar pattern and determining the angles between the steel bar segments and the x-axis and y-axis, when dealing with the arc-shaped steel bar segments in the steel bar pattern, in the embodiments of the present invention, endpoint capture is first performed on each arc segment, that is, the coordinate information of its starting point and ending point is accurately recorded. Subsequently, by connecting the starting point and the ending point, the arc segment is transformed into a virtual straight steel bar segment, which is called the "transformed straight steel bar segment" in the embodiments of the present invention.

[0071] Then, determine the angles between the transformed straight steel bar segment and the x-axis and y-axis, and determine the angles between the transformed straight steel bar segment and the x-axis and y-axis as the angles between the arc-shaped steel bar segment and the x-axis and y-axis for use in the subsequent selection of the target scale factor.

[0072] For the steel bar segments that are originally straight segments, no additional processing is required, and directly determine the angles between the straight steel bar segments and the x-axis and y-axis for use in the subsequent selection of the target scale factor.

[0073] Optionally, the step of selecting the target scale factor from the scale factor set based on the angle includes: for each steel bar segment, in the case where the angle between the steel bar segment and the x-axis is less than the angle between the steel bar segment and the y-axis, determine the first type of scale factor between the target rectangular bounding box and the target cell on the x-axis as the target scale factor; or, in the case where the angle between the steel bar segment and the x-axis is greater than the angle between the steel bar segment and the y-axis, determine the second type of scale factor between the target rectangular bounding box and the target cell on the y-axis as the target scale factor.

[0074] Precisely selecting the target scale factor from the scale factor set based on the angle between the steel bar segment and the coordinate axis is a crucial step in the embodiments of the present invention, which ensures that during the scaling and drawing process, the steel bar segment can be adjusted with the optimal scale, so as to obtain a beautiful and information-accurate steel bar sketch within the target cell.

[0075] In this embodiment, first judge the angle relationship between the steel bar segment and the x-axis and y-axis, and then select the most suitable scale factor. Specifically, in the case where the angle between the steel bar segment and the x-axis is less than the angle between the steel bar segment and the y-axis, determine the first type of scale factor between the target rectangular bounding box and the target cell on the x-axis as the target scale factor. In the case where the angle between the steel bar segment and the x-axis is greater than the angle between the steel bar segment and the y-axis, determine the second type of scale factor between the target rectangular bounding box and the target cell on the y-axis as the target scale factor. Subsequently, scale the steel bar segment based on the selected target scale factor.

[0076] Optionally, the steps of determining the steel bar sketch of the steel bar pattern based on all the scaled steel bar segments include: splicing the scaled steel bar segments based on the head-to-tail connection order of the steel bar segments in the steel bar pattern to obtain the steel bar sketch of the steel bar pattern; obtaining the actual lengths of all the steel bar segments in the steel bar pattern, the actual angles between the steel bar segments, and the actual radian of the arc steel bar segments, and writing the actual lengths, actual angles, and actual radian into the steel bar sketch.

[0077] After the scaling process is completed, the embodiment of the present invention will accurately splice the scaled steel bar segments according to the head-to-tail connection order of the steel bar segments in the original steel bar pattern. This splicing process strictly follows the original structure of the steel bar pattern to ensure that each part after scaling can be seamlessly docked to form a complete and coherent steel bar sketch.

[0078] Subsequently, the embodiment of the present invention will extract the actual lengths of all the steel bar segments, the actual angles between the steel bar segments, and the actual radian information of the arc steel bar segments from the original steel bar pattern, and write these actual information into the steel bar sketch. Figure 5 The shown steel bar sketch only shows the actual lengths of the steel bar segments.

[0079] The steps provided by the above method for drawing the steel bar sketch with segmented scaling can be as follows: rotate the steel bar pattern, then determine the target rectangular bounding box based on the coordinates of each turning point in the rotated steel bar pattern, calculate the set of scale factors of the target rectangular bounding box and the target cell on the x-axis and y-axis of the coordinate system based on the side lengths of the target rectangular bounding box and the target cell on the x-axis and y-axis, then traverse all the steel bar segments of the steel bar pattern to determine the angles between the steel bar segments and the x-axis and y-axis, select the target scale factor from the set of scale factors based on the angles, scale the steel bar segments based on the target scale factor, and finally determine the steel bar sketch of the steel bar pattern based on all the scaled steel bar segments.

[0080] The embodiment of the present invention automatically outputs the steel bar sketch based on the steel bar pattern, without relying on any manual operation, and outputs a steel bar sketch with high accuracy and close to the hand-drawn effect, thereby solving the technical problem in the related art that the drawing of the steel bar sketch depends on manual intervention, resulting in low drawing efficiency.
