Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
The embodiment of the invention provides a method for correcting a connection relation, as shown in fig. 1, which specifically comprises the following steps:
step S101: three-dimensional and two-dimensional views describing the engineering project are acquired.
In this embodiment, a designer designs a three-dimensional model of the engineering project through engineering modeling software to obtain a three-dimensional view of the engineering project, and then converts the three-dimensional view into a two-dimensional view of the engineering project through engineering modeling software in the later stage; since the conversion of the three-dimensional model map into the two-dimensional map is the prior art, the conversion process is not described herein. The three-dimensional graphics used for representing each object (such as a pipe fitting, a pipeline and equipment) in the engineering project in the three-dimensional view are connected according to the real connection relation among the objects, so that the connection relation of each three-dimensional graphic in the three-dimensional view can truly reflect the connection relation of each object in the engineering project and is in a seamless connection state; in the two-dimensional view, each object in the engineering project is represented by a simple geometric figure, and the real connection relation between each object in the engineering project is not considered in the conversion of the three-dimensional view into the two-dimensional view, so that the two-dimensional figures in the converted two-dimensional view are not in a seamless connection state, namely the real connection relation between each two-dimensional figure in the converted two-dimensional view cannot be reflected. For example, as shown in fig. 2, a schematic diagram of a three-dimensional view of an engineering project is shown, in which three-dimensional graphs of objects in fig. 2 are tightly connected, without gaps in the middle, and in a seamless connection state, as shown in fig. 3, a schematic diagram of a two-dimensional view of the engineering project before being modified is shown, in fig. 3, two-dimensional graphs of objects in fig. 3 are not tightly connected, with gaps in the middle, and no longer in a seamless connection state, as shown in fig. 4, a schematic diagram of another two-dimensional view of the engineering project before being modified is shown, in fig. 4, two-dimensional graphs of objects in fig. 4 are not tightly connected, with gaps in the middle, and no longer in a seamless connection state.
Specifically, step S101 includes:
when a view mode switching instruction for the engineering project is detected, a three-dimensional view of the engineering project is obtained, and a two-dimensional view switched according to the view mode switching instruction is obtained.
Fine view mode, medium view mode and coarse view mode are typically included in engineering modeling software; wherein, the three-dimensional view of the engineering project is displayed in the fine view mode, and the two-dimensional view of the engineering project is displayed in the medium view mode and the rough view mode. When the fine view mode is adjusted to the medium view mode or the rough view mode by the view mode switching instruction, the displayed three-dimensional view needs to be switched to the two-dimensional view; when the medium view mode or the coarse view mode is adjusted to the fine view mode by the view mode switching instruction, it is necessary to switch the displayed two-dimensional view to the three-dimensional view.
Note that, since the three-dimensional view can reflect the real connection relationship between the respective objects in the engineering project, only the case of adjusting the fine view mode to the middle view mode or the coarse view mode by the view mode switching instruction is considered in the present embodiment, and the case of adjusting the middle view mode or the coarse view mode to the fine view mode by the view mode switching instruction is not considered. For example, FIG. 2 is a three-dimensional view with a view scale of 1:100 in fine view mode, while FIG. 3 is a two-dimensional view with a view scale of 1:100 in medium view mode.
Further, step S101 further includes:
when a scaling adjustment instruction for the engineering project is detected, a three-dimensional view of the engineering project is obtained, and a two-dimensional view adjusted according to the scaling adjustment instruction is obtained.
Defaulting to 100 in engineering modeling software, and when the view proportion is set to be less than 100 through a scaling adjustment instruction, reducing the two-dimensional view is required; when the view scale is set to be greater than 100 by the scale adjustment instruction, it is necessary to enlarge the two-dimensional view.
Since the three-dimensional view can reflect the real connection relationship between the objects in the engineering project, only the case of adjusting the two-dimensional view by the scaling instruction is considered in the present embodiment, and the case of adjusting the three-dimensional view by the scaling instruction is not considered. For example, fig. 2 is a three-dimensional view with a view ratio of 1:100, fig. 3 is a two-dimensional view with a view ratio of 1:100, and fig. 4 is a two-dimensional view with a view ratio of 1:30 in the medium view mode.
Step S102: acquiring a first three-dimensional connection point from the three-dimensional view and a second three-dimensional connection point with a connection relation with the first three-dimensional connection point; wherein the first three-dimensional connection point corresponds to a first object in the engineering project and the second three-dimensional connection point corresponds to a second object in the engineering project.
Wherein, the object is: pipes, tubes, equipment.
Specifically, before step S102, the method further includes:
setting corresponding three-dimensional point connection information for each three-dimensional connection point of each three-dimensional graph according to the connection relation between each three-dimensional graph in the three-dimensional view; wherein the three-dimensional point connection information includes: information of an object to which a target three-dimensional connection point belongs, information of an associated three-dimensional connection point having a connection relationship with the target three-dimensional connection point, and information of an object to which the associated three-dimensional connection point belongs.
In this embodiment, since the designer designs the three-dimensional model of the worker Cheng Xiang in the engineering modeling software, in this embodiment, corresponding three-dimensional point connection information is created for each three-dimensional connection point of each three-dimensional graph according to the connection relationship between each three-dimensional graph in the three-dimensional view of the engineering project; the information of the object to which it belongs (for example, pipe information, equipment information), the information of the three-dimensional connection point to which it is connected, and the information of the object to which it is connected (for example, pipe information, equipment information) can be acquired by the three-dimensional point connection information of any three-dimensional connection point. Thus, the information of the objects such as the pipeline, the pipe fitting, the equipment and the like can be obtained through the three-dimensional point connection information of the three-dimensional connection points.
Further, step S102 specifically includes:
step A1: acquiring a first three-dimensional graph used for representing the first object from the three-dimensional view, and determining the first three-dimensional connection point from the first three-dimensional graph;
step A2: three-dimensional point connection information corresponding to the first three-dimensional connection point is obtained, and a second three-dimensional connection point with a connection relation with the first three-dimensional connection point is obtained from the three-dimensional point connection information.
In this embodiment, the three-dimensional graphics in the three-dimensional view have one or more three-dimensional connection points, and the three-dimensional graphics are connected to each other through the three-dimensional connection points, thereby achieving a seamless connection state.
Step S103: determining a first two-dimensional connection point with a mapping relation with the first three-dimensional connection point and a second two-dimensional connection point with a mapping relation with the second three-dimensional connection point from the two-dimensional view; wherein the first two-dimensional connection point corresponds to the first object and the second two-dimensional connection point corresponds to the second object.
Specifically, before step S103, the method further includes:
step B1: obtaining a target object from a preset object library, and obtaining a three-dimensional graph and a two-dimensional graph for representing the target object;
for example, when the target object is a valve, acquiring a three-dimensional model graph for representing the valve and a two-dimensional geometric graph for representing the valve;
step B2: determining each three-dimensional connection point from the three-dimensional graph, and determining each two-dimensional connection point from the two-dimensional graph;
step B3: setting the same point number for the three-dimensional connection point and the two-dimensional connection point with the mapping relation;
step B4: and forming two-dimensional mapping information of the target object by the point numbers of the three-dimensional connection points in the three-dimensional graph and the point numbers of the two-dimensional connection points in the two-dimensional graph.
In this embodiment, all objects used by the engineering project are contained in the preset object library, for example: pipe fittings, pipelines and equipment. Setting corresponding two-dimensional mapping information for each object in the object library; the two-dimensional mapping information includes: mapping relation between each three-dimensional connection point in the three-dimensional graph of the target object and each two-dimensional connection point in the two-dimensional graph of the target object. It should be noted that, in this embodiment, each type of object has only two-dimensional mapping information corresponding to each object. In practical application, a connection point of a two-dimensional graph and a connection point ID of a three-dimensional graph of a type of object are defined in an object editor, when the connection point IDs are consistent, a mapping relation is represented, and when two-dimensional and three-dimensional connection point coordinate conversion is needed, the other party can be found through the connection point IDs.
Further, step S103 specifically includes:
step C1: determining a target object corresponding to a target three-dimensional connection point aiming at the target three-dimensional connection point, and determining a point number of the target three-dimensional connection point;
the information of a target object which the target three-dimensional connecting point belongs to can be determined through the three-dimensional point continuous information corresponding to the target three-dimensional connecting point;
in this embodiment, the target three-dimensional connection point is a first three-dimensional connection point and a second three-dimensional connection point; it is necessary to determine a first object corresponding to a first three-dimensional connection point and to determine a second object corresponding to a second three-dimensional connection point.
In this embodiment, point attribute information is set for each three-dimensional connection point of each three-dimensional graph in the three-dimensional view, and the point attribute information of one three-dimensional connection point includes a point number; the two-dimensional view is provided with point attribute information for each two-dimensional connection point of each two-dimensional graph, and the point attribute information of one two-dimensional connection point comprises a point number.
Step C2: determining a target two-dimensional graph for representing the target object from the two-dimensional view, and acquiring the point numbers of all two-dimensional connection points in the target two-dimensional graph;
still further, the method further comprises:
and setting an object number for unique identification for each object in the engineering project, so that a three-dimensional graph corresponding to a target object in the three-dimensional view and a two-dimensional graph corresponding to the target object in the two-dimensional view have the same object number.
In this embodiment, graphics attribute information is provided for each three-dimensional graphics in the three-dimensional view, and the graphics attribute information of one three-dimensional graphics includes an object number; and providing graphic attribute information for each two-dimensional graphic in the two-dimensional view, wherein the graphic attribute information of one two-dimensional graphic comprises an object number.
Thus, in step C2, a target three-dimensional graphic having the target object number may be acquired from the three-dimensional view using the target object number of the target object and a target two-dimensional graphic having the target object number may be acquired from the two-dimensional view.
Step C3: acquiring two-dimensional mapping information corresponding to the target object;
c3, acquiring two-dimensional mapping information corresponding to the type of the target object;
step C4: determining a two-dimensional connection point with a mapping relation with the target three-dimensional connection point from the target two-dimensional graph according to the point number of the target three-dimensional connection point, the point number of each two-dimensional connection point in the target two-dimensional graph and the two-dimensional mapping information;
wherein the point number of the target three-dimensional connection point is consistent with the point number of the two-dimensional connection point with the mapping relation, namely, the three-dimensional connection point and the two-dimensional connection point with the same point number have the mapping relation in the three-dimensional graph and the two-dimensional graph.
In this embodiment, the target three-dimensional connection point is a first three-dimensional connection point and a second three-dimensional connection point; it is necessary to determine a first two-dimensional connection point having a mapping relationship with the first three-dimensional connection point and to determine a second two-dimensional connection point having a mapping relationship with the second three-dimensional connection point.
Step S104: and correcting the connection relation between the first two-dimensional connection point and the second two-dimensional connection point according to the connection relation between the first three-dimensional connection point and the second three-dimensional connection point.
Specifically, step S104 includes:
when the first object is a pipeline, setting the coordinates of the first two-dimensional connection point as the coordinates of the second two-dimensional connection point; or when the second object is a pipeline, setting the coordinates of the second two-dimensional connection point as the coordinates of the first two-dimensional connection point.
In the two-dimensional view, the two-dimensional graph corresponding to the pipeline is contracted or extended, so that the two-dimensional graph corresponding to the pipeline and other two-dimensional graphs with connection relations are kept in a seamless connection state. For example, as shown in fig. 5, in order to modify the two-dimensional view shown in fig. 3, fig. 5 is a two-dimensional view with a view ratio of 1:100 in a medium view mode, and two-dimensional graphics of each object in fig. 5 are tightly connected, and have no gap in the middle, and are in a seamless connection state; as shown in fig. 6, in order to modify the two-dimensional view shown in fig. 4, fig. 6 is a two-dimensional view with a view ratio of 1:30 in the medium view mode, and the two-dimensional graphics of each object in fig. 6 are tightly connected, and have no gap in the middle, and are in a seamless connection state.
By the aid of the method and the device, seamless connection states among objects such as the pipeline and the pipe fitting, the pipeline and the device, the pipe fitting and the pipe fitting, the pipe fitting and the device and the like can be guaranteed, and accordingly the modified two-dimensional view can meet display requirements and drawing requirements.
Furthermore, the method comprises the following steps:
and storing the two-dimensional view of the target object in different view proportions into a preset database aiming at the target object, and acquiring the two-dimensional view in the corresponding view proportion from the preset database when the scaling requirement aiming at the target object appears.
By the method, when the same object is zoomed, the saved two-dimensional view is directly acquired, so that the time for zooming the object can be saved, the performance of switching view proportion can be improved, and the performance of engineering modeling software can be greatly improved through a view graph sharing mechanism.
