[0001] The present invention relates to the technical field of engineering drawing, and in particular to a method, device, computer equipment and storage medium for generating component labels. Background Art

[0002] At present, the label writing tools for construction drawings are mainly divided into two categories, one is non-parametric labeling based on two-dimensional planes, and the other is parametric labeling based on BIM models. At present, the software that can realize this function on the market is mainly AutoCAD and Revit under Autodesk. In practical applications, the above two categories of labeling have different defects. On the one hand, non-parametric labeling based on two-dimensional planes needs to create a template first, and reuse it in different positions of the drawing based on the template. Users need to manually adjust according to the drawing specifications, which is a lot of work; at the same time, users need to draw the leader manually, which is a cumbersome process; and non-parametric labeling based on two-dimensional planes cannot meet the situation of automatic update of labeling when some parameters of the component change. On the other hand, the position of the label leader generated in the parametric labeling based on the BIM model is highly random, which is not convenient for flexible control; the leader only covers one drag point, and it is impossible to set a more complex leader shape; and in some cases, the generated text does not meet the drawing specifications.

[0053] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0054] Embodiment 1

[0055] See also Figure 1 This embodiment proposes a method for generating a component label, comprising the following steps:

[0056] S100: Acquire a label model according to the type of a first target component, wherein the label model includes a label leader and a label text box.

[0057] The first target component refers to any component in the engineering drawing. The type of component can be divided according to the shape of the component, such as point-shaped components, linear components, etc. The point-shaped components can be lamps, columns in the top view, etc., and the linear components can be beams, columns in the side view, etc., which are not limited in this embodiment. In this embodiment, the label leader and the label text box are used together as a label model. The label leader is used to indicate the corresponding first target component, and the label text box is used to add text corresponding to the first target component, such as component name, component size, component material, etc. When the background receives a label generation request issued by the user for a certain type of first target component, the corresponding label model can be returned.

[0058] S200: Determine the visibility status of the tag lead.

[0059] The visible and invisible states of the label lead include two states: display and hidden. The display state is that the lead pointing to the target component is usually displayed, and the label text box is displayed at the other end of the lead. The hidden state means that the lead itself is no longer displayed, and only the label text box is displayed near the first target component. This embodiment is described below from different visible and invisible states of the label lead.

[0060] S300: When the visibility state of the label lead is hidden, determining the display form of the label text box according to the type of the target component and a first preset rule.

[0061] In this step, the label leader is hidden, which means that the component label only displays the text box but not the leader. Figure 2A FIG. 1 shows a schematic diagram of a label text box of a dot-shaped component according to the first embodiment of the present invention. Figure 2A It can be seen that the display position of the label text box corresponding to the dot-shaped component G1 can be set to any side of the top, bottom, left or right. Figure 2A In the example, the text box itself is not displayed by default, and only the text inside the text box, such as "vertical text", is displayed. It can be further seen that the order of displayed text is usually set to read from left to right or from bottom to top. This setting method can be determined by a built-in first preset rule. Among them, the first preset rule can be a rule for the relative distance between the label text box and the dot-shaped component, text font, color, reading order, etc., which is set according to various standard drawing specifications. The specific rules may vary depending on different application scenarios, and this embodiment does not limit this. Figure 2B A schematic diagram of a label text box of a linear component according to the first embodiment of the present invention is shown. Figure 2BIn the figure, the linear components include G2 and G3 in the horizontal direction and G4 and G5 in the vertical direction. It can be seen that for the linear components G2 and G3 in the horizontal direction, the display position of the label text box is set on the upper side thereof, and the text reading order is set from left to right, for example Figure 2B The text in the text mark is "I am an example of text annotation 200×300"; for the vertical linear components G4 and G5, the display position of the label text box is set to the left, and the text reading order is set from bottom to top. Similarly, the relative distance between the label text box and the linear component, the text font, color, reading order and other rules can also be set by the first preset rule, and the specific rules can be different according to different application scenarios, which is not limited in this embodiment.

[0062] S400: When the visibility state of the label lead is display, the display form of the label text box is determined according to the composition structure of the label lead and a second preset rule.

[0063] When the label leader is displayed, the label model displays the leader and the text box at the same time. Usually, the label leader starts near the first target component and ends at a vertex of the text box. Figure 3 FIG. 1 shows a schematic flow chart of determining a text box in a label lead display state according to an embodiment of the present invention. Figure 3 As shown, step S400 includes:

[0064] S410: Determine one or more segments included in the tag lead.

[0065] The lead in this embodiment may be composed of multiple line segments, and the endpoint of each line segment is called a grip point. Figure 4 Several different label lead styles are shown. These label leads can be adjusted by dragging the grip points. The specific adjustment rules include that when any first grip point in the label lead is moved, all grip points before the first grip point remain stationary, and all grip points after the first grip point move synchronously with the first grip point. Figure 4 In the figure, the solid line represents the lead after adjustment is completed, and the dotted line represents the lead during adjustment.

[0066] S420: Determine the display position and text order of the label text box according to the direction of the segment.

[0067] When the label leader includes multiple segments, the direction of the last segment has a certain correspondence with the label text box. Specifically, when the last segment is horizontal, if the direction of the last segment from the first starting point to the first end point is the positive direction of the x-axis, the lower right corner of the label text box is close to the first end point; if the direction of the last segment from the first starting point to the first end point is the negative direction of the x-axis, the lower left corner of the label text box is close to the first end point. Figure 5 A schematic diagram showing the corresponding relationship between the horizontal leader and the text box in the first embodiment of the present invention is shown.

[0068] When the last segment is in a vertical direction, if the direction of the last segment from the second starting point to the second end point is the positive direction of the y-axis, the upper left corner of the label text box is close to the second end point; if the direction of the last segment from the second starting point to the second end point is the negative direction of the y-axis, the lower left corner of the label text box is close to the first end point. Figure 6 A schematic diagram showing the corresponding relationship between the vertical lead and the text box in the first embodiment of the present invention is shown.

[0069] It should be noted that for inclined label leaders, there is a certain positional correspondence between the leader and the text box, also known as an adsorption relationship. When you drag the text box, the leader will rotate around the text box. Figure 7 The figure shows the moving relationship between the text box and the individual leader lines. Figure 7 As shown, when the text frame is continuously dragged, the inclined leader will be located at different positions of the frame accordingly. Specific adsorption rules include: when the lead line is tilted at (0,10], it is automatically marked as horizontal; when the tilt angle is (10,30] and (30,37.5], it is automatically adsorbed on the 30 degree line; when the tilt angle is (37.5,45] and (45,52.5], it is automatically adsorbed on the 45 degree line; when the tilt angle is (52.5,60] and (60,80], it is automatically adsorbed on the 60 degree line; when the tilt angle is (80,90], it is automatically marked as vertical, which is effective on the currently drawn lead line; when the tilt angle is (0,90), the adsorption point is the lower left corner point; when the tilt angle is 90 degrees, the adsorption point is directly below; when the tilt angle is (90,180), the adsorption point is the lower right corner point; when the tilt angle is 180 degrees, the adsorption point is directly to the right; when the tilt angle is (180,270), the adsorption point is the upper right corner point; when the tilt angle is 270 degrees, the adsorption point is directly above; when the tilt angle is (270,360), the adsorption point is the upper left corner point; when the tilt angle is 360 / 0 degrees, the adsorption point is the directly left corner point.

[0070] S430: Determine the relative distance between the label text box and the last segment according to the second preset rule.

[0071] The second preset rule may be the relative distance between the label text box and the leader segment set according to various standard drawing specifications, or rules on text font, color, reading order, etc., which may vary depending on different application scenarios, and this embodiment does not impose any restrictions on this.

[0072] Through the above steps, this embodiment can determine the specific display mode of the label model, thereby improving the efficiency of generating corresponding labels for target components and ensuring standardization.

[0073] Furthermore, this embodiment may also generate a second label lead line and a second label text box that correspond to the mirror image based on the generated first label lead line and the first label text box based on a preset reference surface. Figure 8 FIG. 2 shows a schematic diagram of generating a mirror label in an embodiment of the present invention. Figure 8 As shown, the user can select different reference planes to generate corresponding mirror labels, which is suitable for scenes with symmetrical building structures and can further improve the efficiency of generating labels.

[0074] S500: Add corresponding text in the label text box.

[0075] This step can automatically add text by obtaining the properties of the target component, or the user can manually add text. The method of automatically adding text may include: the label text box obtains the first property information of the first target component, and automatically adds the first property information to the label text box. The first property information here can be the name information, size information, material information, etc. related to the first target component pre-stored in the corresponding database. By automatically adding text, the efficiency of label generation can be improved. Furthermore, the text added in this embodiment can also change with the change of the target component. Specifically, on the basis of the label text box moving from the first target component to the second target component, the label text box obtains the second property information of the second target component, and replaces the first property information in the label text box with the second property information. The above steps can achieve a strong association between the marking label and the main component, and ensure the accuracy of the marking label.
