The embodiment of the application provides a method for marking structure dimensions, which is mainly applied to dimension marking of house line legs, line leg design is carried out by adopting Building design software, generally, Revit software can be adopted, the Revit software is constructed for a Building Information Model (BIM), and the method can help architects to design, build and maintain buildings with better quality and higher energy efficiency. According to the embodiment of the application, the terminal equipment is used for executing the labeling method of the structure size, or the labeling device of the structure size running on the terminal equipment is used for executing the labeling method of the structure size. The terminal device may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a smart television, a smart robot, a desktop computer, a server computer, and the like.
Referring to fig. 1a, fig. 1a is a first flowchart illustrating a method for marking a structure dimension according to an embodiment of the present disclosure. The structure size labeling method comprises the following steps:
The architectural design software such as Revit software can be deployed in the terminal equipment, and when a user starts the architectural design software on the terminal equipment, a graphical user interface is displayed on a screen of the terminal equipment. The model creation request may be displayed on the graphical user interface for the user by loading a document already stored on the terminal device, or by a drawing operation drawn on the graphical user interface.
Specifically, the model to be labeled may be a house model. For example: the user loads the house model, which has been stored in the terminal device, by using the building design software, thereby displaying a three-dimensional view of the house model on a graphical user interface of the building design software.
As shown in fig. 1b, fig. 1b is a three-dimensional schematic view of a house model provided in the embodiment of the present application, where the house model is formed by combining a plurality of different types of structures, for example, the house model in fig. 1b is formed by combining a plurality of structures such as a top shelter structure, a step structure, a stitch structure, and a fence structure.
The target selection request input on the graphical user interface can be used for selecting a certain structure or certain structures from a three-dimensional view of the model to be marked displayed on the graphical user interface by a user; or drawing a preset structure on the graphical user interface, and automatically identifying a structure similar to the drawn preset structure in the three-dimensional view by software.
For the above two different target selection requests, the ways of determining the target structure are also divided into two types.
In some embodiments, the step of determining a target structure corresponding to the target selection request from a plurality of structures forming the model to be labeled includes:
(1) and acquiring the similarity of each structure in a plurality of structures forming the model to be marked in the three-dimensional view and the preset structure.
(2) And determining the structure with the similarity larger than the preset similarity as the target structure.
The method comprises the steps of obtaining the similarity between each structure and a preset structure by matching the similarity of all the structures forming a model to be marked with a preset structure aiming at a target selection request for drawing the preset structure on a graphical user interface, setting a preset similarity, and determining the structure as the structure to be selected by a user if the similarity of one structure is greater than the preset similarity.
In some embodiments, the step of determining the target structure from a plurality of structures constituting the model to be annotated comprises:
(1) and responding to the target selection request, and determining the structure selected by the target selection request as a target structure.
The structure selected by the target selection request may be determined as the target structure.
Specifically, a display effect may be set, for example, when a user places a cursor of the terminal device on a certain structure of the model to be labeled, a display color of the corresponding structure is changed, so that the user can visually recognize the selected structure.
And 103, responding to a section creation request input on the graphical user interface, and performing segmentation processing on the three-dimensional view to obtain a section view of the model to be labeled.
As shown in fig. 1c, fig. 1c is a schematic cross-sectional view of a model to be labeled according to an embodiment of the present disclosure. The profile creation request may be a request for a user to input a segmentation direction and/or a segmentation angle for segmenting the model to be labeled in the three-dimensional view. When the section creating request is received, the model to be labeled is segmented based on the segmentation direction and/or the segmentation angle included in the section creating request, and therefore a two-dimensional section view of the model to be labeled is obtained.
And 104, screening a plurality of target straight lines from the candidate straight lines where each line segment forming the target structure is located in the three-dimensional view based on the three-dimensional view, the target structure and the section view.
Taking fig. 1b as an example, the leg 10 in fig. 1b includes 11 line segments, which are a first line segment a, a second line segment b, a third line segment c, a fourth line segment d, a fifth line segment e, a sixth line segment f, a seventh line segment g, an eighth line segment h, a ninth line segment i, a tenth line segment j, and an eleventh line segment k, respectively. The essence of the filtering of the target line is to determine whether the line in which the plurality of candidate line segments are located has an intersection with the sectional view.
In some embodiments, the step of selecting at least one target straight line from the candidate straight lines in the three-dimensional view, where each line segment constituting the target structure is located, based on the three-dimensional view, the target structure and the cross-sectional view, includes:
(1) determining a direction vector of a candidate straight line where each line segment forming the target structure is located in the three-dimensional view and a normal vector of the sectional view;
(2) and screening at least one target straight line from the candidate straight lines based on the direction vector and the normal vector of each candidate straight line.
It can be known from the vector theorem that if the product of the direction vector of a straight line and the normal vector of the plane is 0, the straight line is parallel to the plane or is located in the plane, so that the product of the direction vector of each candidate straight line and the normal vector of the cross-sectional view can be obtained according to the theorem, and the candidate straight line whose product result is not 0 is determined as the target straight line. Therefore, it is necessary to obtain a direction vector of each candidate line and a normal vector of the sectional view in the three-dimensional view.
In some embodiments, the step of screening at least one target line from the candidate lines based on the direction vector and the normal vector of each candidate line comprises:
(1.1) calculating the product of the direction vector of each candidate straight line and the normal vector to obtain the product corresponding to each candidate straight line;
and (1.2) determining the corresponding candidate straight line of which the product is not equal to zero in each candidate straight line as the target straight line.
The candidate straight line whose multiplication result is not 0 is determined as the target straight line, for example, the first line segment a, the third line segment c, the fifth line segment e, and the ninth line segment i of the line leg in fig. 1b all have intersections with the cross-sectional view in fig. 1c, so that the straight lines where the first line segment a, the third line segment c, and the fifth line segment e are located are the target straight lines.
In some embodiments, the method further comprises:
(1.1) determining the candidate straight line with the product equal to zero in each candidate straight line as the other straight line, wherein the other straight line is parallel to the section view or the other straight line is in the plane of the section view.
Wherein, the product of the direction vector of the straight line and the normal vector of the plane is 0, and then the straight line is parallel to the plane or is positioned in the plane. For example, the second line segment b, the fourth line segment d, the sixth line segment f, the seventh line segment g, the eighth line segment h, the tenth line segment j, and the eleventh line segment k in fig. 1b are parallel to the cross-sectional view and are in the plane of the cross-sectional view.
And 105, determining a plurality of intersection point coordinates according to the coordinates of intersection points of the target straight line and the section view.
In some embodiments, the step of determining a plurality of intersection coordinates based on the coordinates of the intersection of the target line and the cross-sectional view comprises:
(1) acquiring a first coordinate of any point on the target straight line and a second coordinate of any point on the sectional view;
(2) and determining the coordinates of the intersection point of the target straight line and the section view based on the target direction vector of the target straight line, the first coordinate, the normal vector and the second coordinate, and determining a plurality of coordinates of the intersection point.
Referring to fig. 1d, fig. 1d is a schematic structural diagram of a target line and a cross-sectional view according to an embodiment of the present disclosure. Knowing that the target direction vector of the target straight line is a first coordinate of any point on the target straight line as a normal vector of the sectional view and a second coordinate of any point on the sectional view as a set intersection coordinate t of the target straight line and the sectional view can be determined by a formula. Thereby determining the coordinates of the intersection point of the target straight line and the sectional view.
And 106, carrying out size marking on the target structure in the cross-sectional view based on the coordinates of the plurality of intersection points.
After the intersection point of each target straight line and the cross-sectional view in the cross-sectional view is determined, the coordinate distance between the intersection points can be determined according to the coordinates of the plurality of intersection points, and the actual size is determined according to a certain proportion (for example, 1: 500). Thereby dimensioning the target structure in the cross-sectional view.
The method for marking the structure size provided by the embodiment of the application comprises the following steps: responding to a model establishing request of a model to be annotated, and triggering the graphical user interface to display a three-dimensional view of the model to be annotated corresponding to the model establishing request; responding to a target selection request input on a graphical user interface, and determining a target structure corresponding to the target selection request from a plurality of structures forming the model to be labeled; responding to a profile creation request input on a graphical user interface, and performing segmentation processing on the three-dimensional view to obtain a profile view of the model to be labeled; screening a plurality of target straight lines from candidate straight lines where each line segment forming the target structure is located in the three-dimensional view based on the three-dimensional view, the target structure and the section view; determining a plurality of intersection point coordinates according to the coordinates of intersection points of the target straight line and the section view; and dimensioning the target structure in the cross-sectional view based on the plurality of intersection point coordinates. The target structure is subjected to size marking in a mode of determining the coordinates of the intersection point of the target straight line and the profile view, so that the corresponding position of the target structure on the profile view is prevented from being manually determined, the size marking can be automatically performed, and the size marking efficiency is improved.
In some embodiments, as shown in fig. 2, a method for labeling a structure size is provided, and the method for labeling the structure size includes:
step 201, responding to a model creating request of a model to be annotated, and triggering a graphical user interface to display a three-dimensional view of the model to be annotated corresponding to the model creating request.
As shown in fig. 1b, fig. 1b is a three-dimensional schematic view of a house model provided by an embodiment of the present application, where the house model is formed by combining a plurality of different types of structures, for example, the house model in fig. 1b is formed by combining a plurality of structures such as a top shelter structure, a step structure, a stitch structure, a fence structure, and the like.
The target selection request input on the graphical user interface is used for drawing a preset structure on the graphical user interface, and the software automatically identifies a structure similar to the drawn preset structure in the three-dimensional view. Similarity matching is carried out on all structures forming the model to be marked and a preset structure, and the similarity of each structure and the preset structure is obtained.
And step 203, determining the structure with the similarity larger than the preset similarity as a target structure.
And if the similarity of a certain structure is greater than the preset similarity, determining the structure as the structure to be selected by the user.
And 204, responding to a section creation request input on the graphical user interface, and segmenting the three-dimensional view to obtain a section view of the model to be labeled.
As shown in fig. 1c, fig. 1c is a schematic cross-sectional view of a model to be labeled according to an embodiment of the present disclosure. The profile creation request may be a request for a user to input a segmentation direction and/or a segmentation angle for segmenting the model to be labeled in the three-dimensional view. When the section creation request is received, the to-be-labeled model is segmented based on the segmentation direction and/or the segmentation angle included in the section creation request, so that a two-dimensional section view of the to-be-labeled model is obtained.
And step 205, determining a direction vector of a candidate straight line where each line segment forming the target structure is located in the three-dimensional view and a normal vector of the sectional view.
It can be known from the vector theorem that if the product of the direction vector of a straight line and the normal vector of the plane is 0, the straight line is parallel to the plane or is located in the plane, so that the product of the direction vector of each candidate straight line and the normal vector of the cross-sectional view can be obtained according to the theorem, and the candidate straight line whose product result is not 0 is determined as the target straight line. Therefore, it is necessary to obtain a direction vector of each candidate line and a normal vector of the sectional view in the three-dimensional view.
The candidate straight line whose product result is not 0 is determined as the target straight line, for example, the first line segment a, the third line segment c, the fifth line segment e, and the ninth line segment i of the line foot in fig. 1b all have intersection points with the cross-sectional view in fig. 1c, so that the straight lines where the first line segment a, the third line segment c, and the fifth line segment e are located are the target straight lines.
And 208, acquiring a first coordinate of any point on the target straight line and a second coordinate of any point on the sectional view.
Referring to fig. 1d, fig. 1d is a schematic structural diagram of a target line and a cross-sectional view according to an embodiment of the present disclosure. The target direction vector of the target straight line is known as a first coordinate of any point on the target straight line, the normal vector of the sectional view is known as a second coordinate of any point on the sectional view
Wherein, the coordinate of the intersection point of the target straight line and the section view is set as t which can be determined by a formula. Thereby determining the coordinates of the intersection point of the target straight line and the sectional view.
And 210, carrying out size marking on the target structure in the cross-sectional view based on the coordinates of the plurality of intersection points.
After the intersection point of each target straight line and the cross-sectional view in the cross-sectional view is determined, the coordinate distance between the intersection points can be determined according to the coordinates of the plurality of intersection points, and the actual size is determined according to a certain proportion (for example, 1: 500). Thereby dimensioning the target structure in the cross-sectional view.
