Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a component collision analysis method based on a BIM model according to an embodiment of the present invention. The method can comprise the following steps:
step 101: obtaining a bounding box of the component; wherein, the bounding box of the component is a geometrical body which surrounds the outer contour of the BIM model of the component.
Specifically, the specific type of the bounding box of the component in this step may be set by a designer according to a practical scenario and a user requirement, for example, the bounding box may be a geometric body that only encloses the outer contour of the BIM model of the component, such as the outer contour model of the component; in order to ensure the collision condition between the BIM model of the component determined in this embodiment and the BIM model of each considered component, including the cast-in-place part of the component, the bounding box of the component in this step may also be a cuboid, for example, in which the volume of the outer contour of the BIM model of the surrounding component is the smallest, so that the bounding box of the component can surround the cast-in-place part of the component. The present embodiment does not set any limit to this.
It is understood that the present embodiment is illustrated by taking as an example a collision analysis process of one component (target component) in the prefabricated building and other components (components other than the target component), that is, the component in this step may be one component selected by a user or any component in the prefabricated building that needs to be subjected to collision analysis, and the collision analysis process of other target components in the prefabricated building and corresponding other components may be correspondingly performed in a manner the same as or similar to the method provided in the present embodiment, which is not limited by the present embodiment.
It should be noted that, as to the specific manner of obtaining the bounding box of the component in this step, the designer may set the bounding box according to the practical scenario and the user requirement, and when the bounding box of the component is determined, for example, bounding boxes corresponding to respective BIM models of a preset BIM set (e.g., a BIM model of an assembly building including a plurality of components) and other components are preset in the preset BIM set, the step may directly determine the bounding box of the component; the bounding box of the component may also be generated according to the BIM model of the component, and if the preset BIM set only includes the respective BIM models of the component and other components, this step may generate the bounding box corresponding to the BIM model of the component according to the BIM model of the component. The embodiment does not limit the bounding box of the component as long as the processor can obtain the bounding box of the component in this step.
Correspondingly, the specific manner of generating the bounding box of the component according to the BIM model of the component may be set by a designer, for example, the method may be implemented in the same or similar manner as the bounding box generating method corresponding to the BIM model of the component in the prior art, and this embodiment does not limit this.
Step 102: and acquiring the bounding boxes of the components under consideration in the preset range corresponding to the BIM of the components.
The considered member in this step may be another member (a member other than the target member) whose BIM model is within a preset range corresponding to the BIM model of the member (the target member), that is, another member in the preset BIM set that may collide with the BIM model of the member.
It is understood that, in this step, the considered members in the preset range corresponding to the BIM model of the member may be determined, and then the respective bounding boxes of each considered member may be obtained. For the specific mode of determining the considered component in the preset range corresponding to the BIM model of the component, that is, the specific setting of the preset range, the designer can set the considered component according to the practical scene and the user requirement, for example, other components (other components) except the target component (component) in the preset BIM set can be directly used as the considered component, that is, the preset range is the preset BIM set; a part of other members (other members) except the target member (member) in the preset BIM set may be selected as a considered member, that is, other members more likely to collide with the target member are selected as considered members, that is, the preset range may be smaller than the preset BIM set, for example, a sphere corresponding to the member may be generated according to a preset radius by taking a preset point (for example, a center point or one of four corners) in the BIM model of the member as a center; and performing Boolean collision operation on the sphere and the BIM models of other members in the preset BIM set, and taking the other members corresponding to the BIM models with the collision of the sphere as considered members. The present embodiment does not set any limit to this.
Correspondingly, for the specific manner of acquiring the bounding box of each considered component and the specific type of the acquired bounding box, the same or similar setting manner as the bounding box acquisition manner and type setting of the component (target component) in step 101 may be adopted for setting correspondingly, and this embodiment does not set any limitation.
It should be noted that there is no logical precedence order between this step and step 101, and step 101 may be performed first and then step 102 as shown in this embodiment, or step 102 may be performed first and then step 101, or both steps may be performed simultaneously, as long as the component and the corresponding bounding box of the component under consideration that needs to be analyzed for the collision condition are obtained before step 103, which is not limited in this embodiment.
Step 103: determining the collision condition of the BIM model of the member and the BIM model of each considered member according to the outer contour lines of the corresponding surfaces in the bounding boxes of the member and the considered member; wherein the collision condition includes collision and non-collision.
Among them, the purpose of this step may be to determine whether the member collides with each considered member, such as whether the reinforcing bars of the member collide with the reinforcing bars of the considered member, by determining the collision of the BIM model of the member with the BIM model of each considered member according to the outer contour lines of the corresponding faces in the bounding boxes of the member and the considered member.
Specifically, the specific manner of determining the collision condition between the BIM model of the member and the BIM model of each considered member according to the outer contour lines of the corresponding surfaces in the bounding boxes of the member and the considered member in this step can be set by the designer according to practical situations and user requirements, for example, whether the considered member collides with the member can be determined by sequentially using each surface in the bounding box of the considered member and the corresponding surface in the bounding box of the member; it is also possible to sequentially determine whether a member collides with each of the considered members corresponding to the face, using each of the faces in the bounding box of the member and the corresponding face in the bounding box of the corresponding plurality of considered members in sequence. The present embodiment does not set any limit to this.
It should be noted that, when determining whether the considered member collides with the member by sequentially using each surface in the bounding box of the considered member and the corresponding surface in the bounding box of the considered member, the steps may be as shown in fig. 2, and include:
step 201: and projecting the outer contour line of the current surface in the bounding box of the currently considered component into the coordinate system of the corresponding surface in the bounding box of the component to obtain the projection line corresponding to the current surface.
It is understood that the current consideration component in this step may be a consideration component for performing a collision condition analysis with the component at the current time; the current surface in this step may be one surface in a bounding box utilized by a consideration member for performing a collision analysis with the member at the current time; the corresponding face in this step may be a corresponding face in the bounding box of the previously corresponding member.
In this step, the specific obtaining manner of the outer contour line of the current surface and the projection line corresponding to the current surface may be set correspondingly in a manner the same as or similar to that of the planar projection technology in the prior art, which is not limited in this embodiment.
Step 202: judging whether the projection line is equal to the outer contour line in the corresponding surface; if yes, go to step 203.
It is understood that the purpose of this step may be to determine whether two surfaces are parallel by judging whether the projection line corresponding to the current surface of the currently considered component is equal to the length of the outer contour line in the corresponding surface; if so, the component currently under consideration may collide with the component; if not, the current face may be changed to the next face of the currently considered component, and step 201 is entered again; if the projection line corresponding to each surface of the currently considered member is not equal to the outer contour line in the corresponding surface, it may be determined that the BIM model of the currently considered member does not collide with the BIM model of the member, and the next considered member is taken as the currently considered member, and the process proceeds to step 201 again.
Step 203: judging whether the distance between the center point of the projection line and the center point of the outer contour line in the corresponding surface is smaller than or equal to a threshold value; if yes, go to step 204.
It should be noted that, in this step, when the length of the projection line corresponding to the current surface of the currently considered component is equal to that of the outer contour line in the corresponding surface, that is, when the two surfaces are parallel, it may be determined whether the component is in contact with the currently considered component, that is, a collision occurs, by determining whether the distance between the center points of the two surfaces (the center point of the projection line and the center point of the outer contour line) is less than or equal to a threshold value; if the value is less than or equal to the threshold value, it may be determined that step 204 is performed to determine that the BIM model of the currently considered component collides with the BIM model of the component; if the current surface is larger than the threshold value, the current surface can be changed to the next surface of the currently considered component, and step 201 is entered again; if the projection line corresponding to each surface of the currently considered component is not equal to the outer contour line in the corresponding surface, or the distance between the center point of the projection line and the center point of the outer contour line is not less than or equal to the threshold, it may be determined that the BIM model of the currently considered component and the BIM model of the component do not collide, and the next considered component is taken as the currently considered component, and step 201 is performed again.
Specifically, the setting of the threshold in this step may be set by a designer, for example, the threshold may be 1 mm, and this embodiment does not limit this.
Step 204: determining that the BIM model of the currently considered component collides with the BIM model of the component.
It is understood that, in this step, it is determined that the currently considered member collides with the member by determining that the BIM model of the currently considered member collides with the BIM model of the member, that is, determining that the collision between the BIM model of the currently considered member and the BIM model of the member is collision.
Further, in order to better analyze the collision between the members, the present embodiment may further automatically analyze the steel bar portion where the collision occurs between the members, that is, the present embodiment may further include: and performing Boolean collision operation on the steel bars in the BIM model of the component and the steel bars in the BIM model of each component, which is considered to collide with the component, and determining the part of the steel bars which collide with the component. If the BIM model of the currently considered member collides with the BIM model of the currently considered member, boolean collision operation can be performed on the steel bars in the BIM model of the currently considered member and the steel bars in the BIM model of the currently considered member, so as to determine the steel bar part of the member where the BIM model of the currently considered member collides with the BIM model of the currently considered member.
Correspondingly, in order to enable a user to better understand the steel bar part where collision occurs between the components, the present embodiment may further include: highlighting the impacted rebar portion.
Further, this embodiment may further include a step of processing the steel bar portion that has collided, and since the steel bar collision processing manner among the same 2 members is different under different environments or different requirements, this embodiment may further include: and generating and displaying a preset processing rule corresponding to the collided rebar part so as to automatically modify the collided rebar part according to the preset processing rule (processing mode) selected by a user.
In the embodiment of the invention, the collision condition of the BIM model of the member and the BIM model of each considered member is determined according to the outer contour lines of the corresponding surfaces in the members and the bounding boxes of the considered members, and whether the members in the assembled building collide can be determined by utilizing the members and the bounding boxes of the considered members which may collide with the members, so that the automatic analysis of the collision condition between the members is realized, the workload of related personnel is reduced, the condition of errors in manual analysis is avoided, and the user experience is improved.
