[0040] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0042] In a first aspect, an embodiment of the present application provides a method for matching bridge models.

[0043] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the bridge model matching method of this application. Figure 1 As shown in Figure 2, the bridge model matching methods include:

[0044] Step S10: Determine a transformation matrix based on a first angle between a preset straight line in the target bridge model in the non-geod coordinate system and a preset reference line in the coordinate system where the straight line is located, and a second angle between the preset straight line and the preset reference line in the geodetic coordinate system.

[0045] It should be noted that, in order to facilitate modeling and calculation, millimeters are usually used as units when modeling bridges, and the bridge model is established with the longitudinal axis of the bridge as the X-axis and the transverse axis of the bridge as the Y-axis (that is, in a non-geod coordinate system); this modeling method provides great convenience in modeling and later visualization of results, however, when the model needs to be matched with other models, great difficulties are often encountered; in order to solve this problem, the embodiment of the present application proposes a bridge model matching method to achieve effective matching of bridge models.

[0046] For example, in an embodiment of the present application, the target bridge model in the non-geodetic coordinate system includes various bridge models in multiple stages, such as the GIS model in the planning stage, the BIM model and FEM model in the design stage, and the in-depth BIM model in the construction stage; the preset straight line refers to a straight line used as a reference when performing coordinate conversion, which can usually be any straight line in the target bridge model, used to help determine the conversion relationship of the coordinate system; the preset baseline refers to a straight line used as a reference standard in the coordinate system, usually the X-axis or Y-axis, or other straight lines parallel to the X-axis or Y-axis, used to determine the conversion matrix or calculate the angle; the geodetic coordinate system refers to a coordinate system defined based on the surface of the earth; the first angle is the angle between the preset straight line and the preset baseline in the non-geodetic coordinate system, reflecting how the coordinate system of the target bridge model is aligned with the baseline; the second angle is the angle between the preset straight line and the preset baseline in the geodetic coordinate system; the conversion 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, which determines how the two coordinate systems are aligned with each other.

[0047] Specifically, by calculating the angle (first angle) between the preset straight line and the baseline in the non-geod coordinate system and the angle (second angle) between the preset straight line and the baseline in the geodetic coordinate system, the rotation relationship between the two coordinate systems can be determined. That is, these two angles accurately describe the relative rotation relationship between the non-geod coordinate system and the geodetic coordinate system. Then, a transformation matrix can be constructed by combining the first angle and the second angle, and then the target point in the target bridge model can be transformed from the non-geod coordinate system to the geodetic coordinate system based on the transformation matrix.

[0048] Step S20: Determine 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 geodetic coordinate system.

[0049] 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, the point may be located at the bottom of a bridge pier. The first coordinate of any target point on the target bridge model (the first coordinate is the coordinate of the target point in the non-geod coordinate system) and the second coordinate of the target point in the geodetic coordinate system are substituted into the following calculation formula to obtain a translation matrix. The calculation formula is:

[0050]

[0051] Where, is the translation matrix; is the first coordinate; is the second coordinate, where the translation matrix The specific expression is: .

[0052] Step S30: For each target point on the target bridge model, the target coordinates of the target point in the geodetic coordinate system are determined based on the transformation matrix, the translation matrix, the preset scaling factor, and the coordinates of the target point.

[0053] Exemplarily, in an embodiment of the present application, the translation matrix is ​​used to represent the translation state of the target bridge model coordinate system relative to the geodetic coordinate system. The position of the coordinate origin can be adjusted through the translation matrix 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 target bridge model coordinate system 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 0.001. The size of the coordinate system can be adjusted through the scaling factor so that the scale between the non-geod coordinate system and the geodetic coordinate system is consistent.

[0054] Specifically, the target point coordinates are rotated or transformed using a transformation matrix, the target point coordinate positions are adjusted using a translation matrix, and the target point coordinates are appropriately scaled based on a scaling factor to adapt them to the scale of the geodetic coordinate system. This approach accurately maps each target point on the target bridge model to the geodetic coordinate system, ensuring that the target bridge model accurately represents the actual location of the target bridge in the geodetic coordinate system.

[0055] Step S40: Determine a 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, so as to implement information mapping according to the mapping relationship.

[0056] Exemplarily, in an embodiment of the present application, the first component refers to any specific component in the target bridge model, such as the beams, piles, columns, etc. of the target bridge; the two end points refer to the starting point and end point of the first component, and the target coordinates corresponding to the two end points refer to the target coordinates of the starting point of the first component in the geodetic coordinate system and the target coordinates of the end 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 and coordinate ranges of the two end points are both known values, the target coordinates of the two end points 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, through which the information in the target bridge model can be mapped to the BIM model.

[0057] It is understandable that before establishing the mapping relationship, the BIM model and the target bridge model need to be coded separately to efficiently distinguish and identify various components. The coding content includes information such as model category, structural location, component location, component category, and component number. For example, the number is BI01020136, where "BI" represents the BIM model, "01" indicates that the structural location is the substructure, "02" indicates that the component location is the foundation, "01" indicates that the component category is the pile foundation, and "36" indicates the 36th pile foundation. By uniquely coding each component in the model, different components can be effectively identified and distinguished, ensuring data consistency and accuracy.

[0058] 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 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 can be obtained. Then, by comparing the positional relationship between the two, a 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 transmission between different bridge models can be realized, and then the information in the target bridge model can be accurately mapped to the BIM model, ensuring that the two can seamlessly connect and work together in actual applications.

[0059] The present application determines a transformation matrix by calculating 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 the coordinate system in which it is located, and a second angle between the preset straight line and the preset reference line in the geodetic coordinate system; determines a translation matrix based on the first coordinates of any target point on the target bridge model and the second coordinates of the target point in the geodetic coordinate system. Since the coordinate directions of the target bridge model and the geodetic coordinate system may be inconsistent, the calculation of the angle, the establishment of the transformation matrix and the translation matrix ensure the spatial alignment between different models, effectively eliminate the difference in coordinate systems, and enable different models to correspond in space; for each target point on the target bridge model, the target coordinates of the target point in the geodetic coordinate system are determined based on the transformation matrix, the translation matrix, the preset scaling factor, and the coordinates of the target point. The introduction of the scaling factor ensures that the model after the coordinate transformation has a consistent scale in space, avoiding errors caused by inconsistent scales; determines a 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. The mapping relationship provides a standardized way to achieve information mapping between models, ensuring accurate data transmission and effective integration.

[0060] Furthermore, in one embodiment, determining the transformation matrix based on a first angle between a preset straight line in the target bridge model in the non-geod coordinate system and a preset reference line in the coordinate system where the straight line resides, and a second angle between the preset straight line and the preset reference line in the geodetic coordinate system, includes:

[0061] Substituting the first angle and the second angle into a first calculation formula to obtain a conversion matrix, the first calculation formula is as follows:

[0062]

[0063] Where, is the first angle; is the second angle; is the transformation matrix.

[0064] Exemplarily, in the embodiment of the present application, the first angle and the second angle Substitute the following calculation formula to obtain the transformation matrix , the calculation formula is as follows:

[0065]

[0066] Furthermore, 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:

[0067] Substitute the transformation matrix, translation matrix, preset scaling factor, and 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:

[0068]

[0069] Where, is the transformation matrix; is the translation matrix; is the preset zoom factor; is the coordinate of the target point; is the target coordinate of the target point in the geodetic coordinate system.

[0070] For example, in the embodiment of the present application, the conversion matrix , translation matrix , preset zoom factor , the coordinates of the target point Substitute the following calculation formula to obtain the target coordinates of the target point in the geodetic coordinate system , the calculation formula is:

[0071]

[0072] Furthermore, in one embodiment, referring to Figure 2 As shown, the mapping relationship between the target bridge model and the BIM model is determined 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, including:

[0073] Step S401: for each first component in the target bridge model, determining whether the target coordinates of both end points of the first component are within the coordinate range;

[0074] Step S402: If yes, construct a mapping relationship between the first component and the second component;

[0075] Step S403: If not, the mapping relationship between the first component and the second component is not constructed.

[0076] For example, in an embodiment 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 end point are both within the coordinate range [P1, P2]. If the target coordinates of both the starting point and the end point 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 is established between the two to ensure that their positions are consistent. If the target coordinates of any of the endpoints are not within the coordinate range, the mapping relationship between the first component and the second component is not established to avoid mismatching components being incorrectly associated. 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.

[0077] It should be noted that, referring to Figure 3 As shown, the local coordinate system of the BIM model (X B Axis, Y B Axis) and the local coordinate system of the FEM model (X F Axis, Y F Axis) defines the component positions in their respective models. Assuming that the first component in the FEM model includes component 1, component 2, and component 3, 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 end points of component 1 in the geodetic coordinate system in the FEM model and the coordinate range corresponding to component 1 in the BIM model. The moment and displacement information of component 1 is then transferred to the corresponding component 1' in the BIM model through this mapping relationship.

[0078] Furthermore, in one embodiment, the mapping of information according to the mapping relationship includes:

[0079] Based on the mapping relationship, 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, wherein the response information includes moment information and displacement information.

[0080] Exemplarily, in an embodiment of the present application, the response information includes torque information and displacement information. After the mapping relationship between the first component and the second component is established, the response information can be transmitted through the mapping relationship. Specifically, the torque 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 a valuable reference for subsequent design, construction and maintenance. In this way, information transmission between the two models can be achieved, ensuring the rationality of the bridge structure design and the accuracy of the construction process.

[0081] Furthermore, in one embodiment, the preset straight line is determined based on a line connecting any two points in the target bridge model.

[0082] For example, in this embodiment of the present application, "any two points" refers to any two points in the target bridge model, "a connecting line" refers to a line connecting these two points, and "a preset line" refers to a line used as a reference in the target bridge model. Specifically, by selecting any two points in the target bridge model and connecting them, the resulting line can be used as a preset line for subsequent operations such as coordinate transformation and angle calculation.

[0083] Furthermore, in one embodiment, the preset reference line is the X-axis or the Y-axis.

[0084] For example, in the embodiments of the present application, the preset reference line is a standard line used as a reference when performing coordinate transformations. It is typically the X-axis or Y-axis in the coordinate system, but may also be another straight line parallel to the X-axis or Y-axis. Specifically, during the coordinate transformation process, the selected preset reference line may preferably be the X-axis or Y-axis. This serves as a reference line to facilitate determining the transformation matrix or calculating angles, thereby achieving effective matching between models.

[0085] In a second aspect, an embodiment of the present application also provides a system for matching bridge models.

[0086] In one embodiment, referring to Figure 4 , Figure 4 This is a functional module diagram of the bridge model matching system embodiment of this application. Figure 4 As shown, the bridge model matching system includes:

[0087] a first processing module for determining a transformation matrix based on a first angle between a preset straight line in the target bridge model in the non-geod coordinate system and a preset reference line in the coordinate system where the straight line resides, and a second angle between the preset straight line and the preset reference line in the geodetic coordinate system;

[0088] A second processing module is used to determine a translation matrix based on a first coordinate of any target point on the target bridge model and a second coordinate of the target point in the geodetic coordinate system;

[0089] A third processing module is configured to determine the coordinates of each target point on the target bridge model in a geodetic coordinate system based on the transformation matrix, the translation matrix, the preset scaling factor, and the coordinates of the target point, so as to achieve coordinate conversion;

[0090] The fourth processing module 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 and end 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 information mapping according to the mapping relationship, wherein the component information includes the starting point, end point and coordinate range of the component.

[0091] Furthermore, in one embodiment, the first processing module is specifically configured to:

[0092] Substituting the first angle and the second angle into a first calculation formula to obtain a conversion matrix, the first calculation formula is as follows:

[0093]

[0094] Where, is the first angle; is the second angle; is the transformation matrix.

[0095] Furthermore, in one embodiment, the third processing module is specifically configured to:

[0096] Substitute the transformation matrix, translation matrix, preset scaling factor, and 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:

[0097]

[0098] Where, is the transformation matrix; is the translation matrix; is the preset zoom factor; is the coordinate of the target point; is the target coordinate of the target point in the geodetic coordinate system.

[0099] Furthermore, in one embodiment, the fourth processing module is specifically configured to:

[0100] For each first component in the target bridge model, determining whether target coordinates of both end points of the first component are within the coordinate range;

[0101] If so, construct a mapping relationship between the first component and the second component;

[0102] If not, the mapping relationship between the first component and the second component is not constructed.

[0103] Furthermore, in one embodiment, the fourth processing module is further configured to:

[0104] Based on the mapping relationship, 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, wherein the response information includes moment information and displacement information.

[0105] Furthermore, in one embodiment, the first processing module is further configured to:

[0107] Furthermore, in one embodiment, the first processing module is further configured to:

[0108] The preset reference line is the X axis or the Y axis.

[0109] The present application determines a transformation matrix by calculating 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 the coordinate system in which it is located, and a second angle between the preset straight line and the preset reference line in the geodetic coordinate system; determines a translation matrix based on the first coordinates of any target point on the target bridge model and the second coordinates of the target point in the geodetic coordinate system. Since the coordinate directions of the target bridge model and the geodetic coordinate system may be inconsistent, the calculation of the angle, the establishment of the transformation matrix and the translation matrix ensure the spatial alignment between different models, effectively eliminate the difference in coordinate systems, and enable different models to correspond in space; for each target point on the target bridge model, the target coordinates of the target point in the geodetic coordinate system are determined based on the transformation matrix, the translation matrix, the preset scaling factor, and the coordinates of the target point. The introduction of the scaling factor ensures that the model after the coordinate transformation has a consistent scale in space, avoiding errors caused by inconsistent scales; determines a 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. The mapping relationship provides a standardized way to achieve information mapping between models, ensuring accurate data transmission and effective integration.
