For example, by coordinate transformation and information mapping to improve the dimension of information expression and the efficiency of model management. Among them, the BIM model mainly focuses on building information and does not contain response information. Therefore, in the information mapping process, it is usually necessary to map the information in other bridge models to the BIM model. However, due to the large differences between different models, it is impossible to perform unified matching of models. Therefore, how to provide a unified and effective model matching method has become an important problem to be solved urgently at present. Summary of the Invention

Detailed Embodiments

[0019] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0021] In a first aspect, an embodiment of this application provides a method for bridge model matching.

[0022] In one embodiment, with reference to Figure 1 , Figure 1 is a schematic flowchart of an embodiment of the method for bridge model matching of this application. As Figure 1 shown, the method for bridge model matching includes: Step S10: Determine a transformation matrix based on a first angle between a preset straight line in a target bridge model in a non-geodetic coordinate system and a preset reference line in its coordinate system, and a second angle between the preset straight line and a preset reference line in the geodetic coordinate system.

[0023] It should be noted that for the convenience of modeling and calculation, the millimeter unit system is usually used in bridge modeling, and the bridge longitudinal axis is used as the X-axis and the bridge transverse axis is used as the Y-axis to establish a bridge model (i.e., in a non-geodetic coordinate system); this modeling method provides great convenience in modeling and the visualization of later results. However, when it is necessary to match the model with other models, great difficulties are often encountered; to solve this problem, an embodiment of this application proposes a method for bridge model matching to achieve effective matching of bridge models.

[0024] Exemplarily, in an embodiment of this application, the target bridge model in the non-geodetic coordinate system includes various bridge models in multiple stages, such as a GIS model in the planning stage, a BIM model, a FEM model in the design stage, and a detailed BIM model in the construction stage, etc.; the preset straight line refers to the straight line used as a reference during coordinate transformation, which can usually be any straight line in the target bridge model and is used to help determine the transformation relationship of the coordinate system; the preset reference line refers to the straight line used as a reference standard in the coordinate system, usually the X-axis or the Y-axis, or other straight lines parallel to the X-axis or the Y-axis, and is used to determine the transformation matrix or calculate the angle; the geodetic coordinate system refers to the coordinate system defined based on the earth's surface; the first angle is the angle between the preset straight line and the preset reference line in the non-geodetic coordinate system, which reflects how the coordinate system of the target bridge model aligns with the reference line; the second angle is the angle between the preset straight line and the preset reference line in the geodetic coordinate system; the transformation matrix represents the rotation or transformation relationship between the coordinate system corresponding to the target bridge model (i.e., the non-geodetic coordinate system) and the geodetic coordinate system, and determines how the two coordinate systems align with each other.

[0025] Specifically, the rotation relationship between the two coordinate systems can be determined by calculating the angle (the first angle) between the preset straight line and the reference line in the non-geodetic coordinate system and the angle (the second angle) between the preset straight line and the reference line in the geodetic coordinate system. That is, these two angles accurately describe the relative rotation relationship between the non-geodetic coordinate system and the geodetic coordinate system. Furthermore, a transformation matrix can be constructed by combining the first angle and the second angle, and then based on the transformation matrix, the target points in the target bridge model can be transformed from the non-geodetic coordinate system to the geodetic coordinate system.

[0026] Step S20: Determine the translation matrix based on the first coordinate of any target point on the target bridge model and the second coordinate of the target point in the geodetic coordinate system.

[0027] Exemplarily, in the embodiment of the present application, the target point refers to any point on the finite element model of the target bridge. For example, this point can be located at the bottom of the pier. Substitute the first coordinate of any target point on the target bridge model (this first coordinate is the coordinate of the target point in the non-geodetic coordinate system) and the second coordinate of the target point in the geodetic coordinate system into the following calculation formula to obtain the translation matrix. The calculation formula is:

[0028] In the formula, is the translation matrix; is the first coordinate; is the second coordinate, where the translation matrix The specific expression of is: .

[0029] Step S30: For each target point on the target bridge model, determine the target coordinate of the target point in the geodetic coordinate system based on the transformation matrix, the translation matrix, the preset scaling factor, and the coordinate of the target point.

[0030] Exemplarily, in the embodiment of the present application, the translation matrix is used to represent the translation state of the coordinate system of the target bridge model relative to the geodetic coordinate system. By the translation matrix, the position of the coordinate origin can be adjusted to ensure that the coordinate origin of the target bridge model is aligned with the corresponding position in the geodetic coordinate system; the preset scaling factor represents the proportional relationship between the coordinate system of the target bridge model and the geodetic coordinate system, which can be determined according to actual needs and is not limited here. For example, the scaling factor can preferably be taken as 0.001. By the scaling factor, the size of the coordinate system can be adjusted to make the scales of the non-geodetic coordinate system and the geodetic coordinate system consistent.

[0031] Specifically, the coordinates of the target points are rotated or transformed through a transformation matrix, the position of the target point coordinates is adjusted by applying a translation matrix, and the target point coordinates are appropriately scaled according to the scaling factor to adapt to the scale of the geodetic coordinate system. In the above manner, each target point on the target bridge model can be accurately mapped into the geodetic coordinate system, thereby ensuring that the target bridge model can accurately represent the actual position of the target bridge in the geodetic coordinate system.

[0032] Step S40: Determine the mapping relationship between the target bridge model and the BIM model based on the target coordinates corresponding to the two endpoints of the first component in the target bridge model and the coordinate range of the second component in the BIM model, so as to implement the mapping of information according to the mapping relationship.

[0033] Exemplarily, in the embodiment of the present application, the first component refers to any specific component in the target bridge model, such as the beam, pile, column, etc. of the target bridge; the two endpoints refer to the starting point and the ending point of the first component, and the target coordinates corresponding to the two endpoints refer to the target coordinates of the starting point of the first component in the geodetic coordinate system and the target coordinates of the ending point of the first component in the geodetic coordinate system; the coordinate range of the second component refers to the coordinate range of any second component in the BIM model, wherein the target coordinates of the two endpoints and the coordinate range are all known values, the target coordinates of the two endpoints can be directly obtained from the target bridge model, and the coordinate range can be directly obtained from the BIM model; the mapping relationship refers to establishing a corresponding relationship between the components in the target bridge model and the components in the BIM model, and through this mapping relationship, the information in the target bridge model can be mapped into the BIM model.

[0034] It can be understood that before constructing the mapping relationship, the BIM model and the target bridge model need to be encoded respectively to efficiently distinguish and identify various components; among them, the encoding content includes information such as model category, structural position, component position, component category, and component number, etc.; for example, the number is BI01020136, where "BI" represents the BIM model, "01" represents the structural position as the substructure, "02" represents the component position as the foundation, "01" represents the component category as the pile foundation, and "36" represents the 36th pile foundation. By uniquely encoding each component in the model, different components can be effectively identified and distinguished, ensuring the consistency and accuracy of the data.

[0035] Specifically, after encoding the components, each first component in the target bridge model can be selected one by one according to the encoding results, and the target coordinates corresponding to both ends of the first component in the target bridge model and the coordinate range of the second component in the BIM model can be obtained. Then, by comparing the positional relationships of the two, the mapping relationship between the first component in the target bridge model and the second component in the BIM model can be established. Based on this mapping relationship, information transfer between different bridge models can be realized, and thus the information in the target bridge model can be accurately mapped to the BIM model, ensuring seamless docking and collaborative work between the two in practical applications.

[0036] In this application, a transformation matrix is determined through the first angle between a preset straight line in the target bridge model in a non-earth coordinate system and a preset reference line in its coordinate system, and the second angle between the preset straight line and the preset reference line in the earth coordinate system. Based on the first coordinate of any target point on the target bridge model and the second coordinate of the target point in the earth coordinate system, a translation matrix is determined. Since the coordinate directions of the target bridge model and the earth coordinate system may be inconsistent, the calculation of the angles, and the establishment of the transformation matrix and the translation matrix ensure the spatial alignment between different models, effectively eliminating the differences in the coordinate systems and enabling different models to correspond spatially. For each target point on the target bridge model, based on the transformation matrix, the translation matrix, a preset scaling factor, and the coordinates of the target point, the target coordinates of the target point in the earth coordinate system are determined. The introduction of the scaling factor ensures that the model after coordinate transformation has a consistent scale in space, avoiding errors caused by inconsistent scales. Based on the target coordinates corresponding to both ends of the first component in the target bridge model and the coordinate range of the second component in the BIM model, the mapping relationship between the target bridge model and the BIM model is determined. This mapping relationship provides a standardized way to realize information mapping between models, ensuring the accurate transmission and effective integration of data.

[0037] Further, in one embodiment, the determining the transformation matrix based on the first angle between a preset straight line in the target bridge model in a non-earth coordinate system and a preset reference line in its coordinate system, and the second angle between the preset straight line and the preset reference line in the earth coordinate system includes: Substituting the first angle and the second angle into a first calculation formula to obtain the transformation matrix, and the first calculation formula is as follows:

[0038] In the formula, is the first angle; is the second angle; is the transformation matrix.

[0039] Exemplarily, in the embodiment of this application, the first angle and the second angle Substitute into the following calculation formula to obtain the transformation matrix , and the calculation formula is as follows:

[0040] Further, in one embodiment, determining the target coordinates of the target point in the geodetic coordinate system based on the transformation matrix, the translation matrix, the preset scaling factor, and the coordinates of the target point includes: Substitute the transformation matrix, the translation matrix, the preset scaling factor, and the coordinates of the target point into the second calculation formula to obtain the target coordinates of the target point in the geodetic coordinate system. The second calculation formula is:

[0041] In the formula, is the transformation matrix; is the translation matrix; is the preset scaling factor; are the coordinates of the target point; are the target coordinates of the target point in the geodetic coordinate system.

[0042] Exemplarily, in the embodiments of the present application, substitute the transformation matrix , the translation matrix , the preset scaling factor , and the coordinates of the target point into the following calculation formula to obtain the target coordinates of the target point in the geodetic coordinate system , and the calculation formula is:

[0043] Further, in one embodiment, as shown in reference to Figure 2 , determining the mapping relationship between the target bridge model and the BIM model based on the target coordinates corresponding to the two end points of the first component in the target bridge model and the coordinate range of the second component in the BIM model includes: Step S401: For each first component in the target bridge model, determine whether the target coordinates of the two end points of the first component are both within the coordinate range; Step S402: If so, construct the mapping relationship between the first component and the second component; Step S403: If not, do not construct the mapping relationship between the first component and the second component.

[0044] Exemplarily, in the embodiments of the present application, for each first component in the target bridge model, it is necessary to determine whether the target coordinates of its starting point and ending point are both within the coordinate range [P1, P2]; if the target coordinates of the starting point and the ending point both meet this condition, it indicates that there is a corresponding relationship between the first component in the target bridge and the second component in the BIM model. At this time, a mapping relationship between the two is established to ensure their positions are consistent; if the target coordinates of any one of the endpoints are not within the coordinate range, the construction of the mapping relationship between this first component and the second component is not carried out, avoiding incorrect association of mismatched components. Through precise coordinate comparison and logical judgment, the correct mapping between the first component in the target bridge model and the second component in the BIM model is ensured, improving the accuracy and reliability of information mapping in subsequent applications.

[0045] It should be noted that, as shown in Figure 3 the local coordinate system (X B axis, Y B axis) of the BIM model and the local coordinate system (X F axis, Y F axis) of the FEM model respectively define the positions of the components in their respective models. Assuming that the first components in the FEM model include component 1, component 2, and component 3, then the mapping relationship between component 1 in the FEM model and component 1' in the BIM model can be established through the coordinates of the two endpoints of component 1 in the FEM model in the geodetic coordinate system and the corresponding coordinate range in the BIM model. Then, through this mapping relationship, the moment and displacement information of component 1 are transmitted to the corresponding component 1' in the BIM model.

[0046] Further, in one embodiment, the implementation of information mapping according to the mapping relationship includes: Based on the mapping relationship, the response information of the first component in the target bridge model is transmitted to the second component in the BIM model to achieve information mapping, and the response information includes moment information and displacement information.

[0047] Exemplarily, in the embodiments of the present application, the response information includes moment information and displacement information. After the mapping relationship between the first component and the second component is constructed, the response information can be transmitted through this mapping relationship. Specifically, the moment information and displacement information of the first component in the target bridge model can be transmitted to the second component in the BIM model, so that the second component in the BIM model can accurately display and store the response information from the target bridge model, providing valuable references for subsequent design, construction, and maintenance. Through the above method, information transmission between the two models can be achieved, ensuring the rationality of bridge structure design and the accuracy of the construction process.

[0048] Further, in one embodiment, the preset straight line is determined based on the connection line between any two points in the target bridge model.

[0049] Exemplarily, in the embodiments of the present application, any two points refer to the points at any two positions in the target bridge model, and the connection line refers to the straight line connecting these two points; the preset straight line is the straight line used as a reference in the target bridge model. Specifically, by selecting any two points in the target bridge model and connecting the straight line formed by these two points, it can be used as the preset straight line for subsequent operations such as coordinate transformation and angle calculation.

[0050] Further, in one embodiment, the preset reference line is the X-axis or the Y-axis.

[0051] Exemplarily, in the embodiments of the present application, the preset reference line is the standard line used as a reference during coordinate transformation, usually the X-axis or the Y-axis in the coordinate system, or other straight lines parallel to the X-axis or parallel to the Y-axis. Specifically, during the coordinate transformation process, the selected preset reference line can preferably be the X-axis or the Y-axis, which helps to determine the transformation matrix or calculate the angle as a reference line, thereby achieving effective matching between models.

[0052] In a second aspect, the embodiments of the present application further provide a system for bridge model matching.

[0053] In one embodiment, referring to Figure 4 , Figure 4 is a schematic diagram of the functional modules of the system embodiment for bridge model matching in the present application. As Figure 4 shown, the system for bridge model matching includes: A first processing module, which is used to determine the transformation matrix based on the first angle between the preset straight line in the target bridge model in the non-geodetic coordinate system and the preset reference line in its coordinate system and the second angle between the preset straight line and the preset reference line in the geodetic coordinate system; A second processing module, which is used to determine the translation matrix based on the first coordinate of any target point on the target bridge model and the second coordinate of the target point in the geodetic coordinate system; A third processing module, which is used to determine the coordinates of each target point on the target bridge model in the geodetic coordinate system based on the transformation matrix, the translation matrix, the preset scaling factor, and the coordinates of the target point for each target point on the target bridge model to achieve coordinate transformation; A fourth processing module, which is used to encode the attributes of the target bridge model and the BIM model to obtain component information, and determine the mapping relationship between the target bridge model and the BIM model based on the starting point, ending point of each component in the target bridge model and the coordinate range corresponding to each component in the BIM model, so as to realize the mapping of information according to the mapping relationship, and the component information includes the starting point, ending point, and coordinate range of the component.

[0054] Further, in one embodiment, the first processing module is specifically configured to: Substitute the first included angle and the second included angle into a first calculation formula to obtain a transformation matrix, and the first calculation formula is as follows:

[0055] In the formula, is the first included angle; is the second included angle; is the transformation matrix.

[0056] Further, in one embodiment, the third processing module is specifically configured to: Substitute the transformation matrix, the translation matrix, a preset scaling factor, and the coordinates of the target point into a second calculation formula to obtain the target coordinates of the target point in the geodetic coordinate system, and the second calculation formula is:

[0057] In the formula, is the transformation matrix; is the translation matrix; is the preset scaling factor; is the coordinates of the target point; is the target coordinates of the target point in the geodetic coordinate system.

[0058] Further, in one embodiment, the fourth processing module is specifically configured to: For each first component in the target bridge model, determine whether the target coordinates of the two end points of the first component are both within the coordinate range; If so, construct a mapping relationship between the first component and the second component; If not, do not construct the mapping relationship between the first component and the second component.

[0059] Further, in one embodiment, the fourth processing module is specifically further configured to: Transmit the response information of the first component in the target bridge model to the second component in the BIM model based on the mapping relationship to implement information mapping, and the response information includes moment information and displacement information.

[0060] Further, in one embodiment, the first processing module is specifically further configured to: The preset straight line is determined based on the connection line between any two points in the target bridge model.

[0061] Further, in one embodiment, the first processing module is specifically further configured to: The preset reference line is the X-axis or the Y-axis.

[0062] This application determines a transformation matrix based on the first angle between a preset straight line in a target bridge model in a non-earth coordinate system and a preset reference line in its coordinate system, and the second angle between the preset straight line and the preset reference line in the earth coordinate system; determines a translation matrix based on the first coordinate of any target point on the target bridge model and the second coordinate of the target point in the earth coordinate system. Since the coordinate directions of the target bridge model and the earth coordinate system may not be consistent, the calculation of the angles and the establishment of the transformation matrix and the translation matrix ensure the spatial alignment between different models, effectively eliminating the differences in the coordinate systems and enabling different models to correspond in space; for each target point on the target bridge model, based on the transformation matrix, the translation matrix, a preset scaling factor, and the coordinates of the target point, determine the target coordinates of the target point in the earth coordinate system. The introduction of the scaling factor ensures that the models after coordinate transformation have a consistent scale in space, avoiding errors caused by inconsistent scales; based on the target coordinates corresponding to the two endpoints of the first component in the target bridge model and the coordinate range of the second component in the BIM model, determine the mapping relationship between the target bridge model and the BIM model. This mapping relationship provides a standardized way to achieve information mapping between models, ensuring the accurate transmission and effective integration of data.
