[0035] In the related art, in the process of generating a three-dimensional tunnel model, sudden cross-sections often appear. In this case, it is usually necessary to perform connection and transition processing on the sudden cross-sections to ensure the integrity of the three-dimensional tunnel model and the continuity of the internal components of the tunnel. However, in the existing technology, it is often necessary to rely on manual connection and transition processing for the sudden sections, which is difficult to operate and leads to low processing efficiency.

[0036] In order to solve the above problems, the present disclosure provides a method, device and system for processing a sudden section of a tunnel three-dimensional model. In response to receiving an instruction to perform transition processing on a sudden section of a target section in a target tunnel model, the first section and the second section corresponding to the target sudden section in the target tunnel model are determined; the first parameter information of the first section and the second parameter information of the second section are obtained; the association relationship between the first section and the second section is determined according to the first parameter information and the second parameter information; according to the association relationship, a processing method corresponding to the association relationship is selected to perform connection processing according to the first section and the second section to obtain the sudden section of the target section after the connection processing. By judging the association relationship between the adjacent first short side and the second section and determining the corresponding connection processing method according to the association relationship, the dependence on manual labor is reduced, the difficulty of connection processing of the sudden section of the section is reduced, and the convenience and processing efficiency of connection processing of the sudden section of the tunnel three-dimensional model are improved.

[0037] Figure 1 is a flow chart of a method for processing a sudden change section of a tunnel three-dimensional model according to an exemplary embodiment. Figure 1 As shown, it should be noted that the method for processing a sudden change section of a three-dimensional tunnel model according to the embodiment of the present disclosure is applied to a device for processing a sudden change section of a three-dimensional tunnel model. Figure 1 As shown, the method may include the following steps:

[0038] Step 101 , in response to receiving an instruction to perform transition processing on a target section mutation segment in a target tunnel model 15 , determining a first section 1 and a second section 2 corresponding to the target mutation segment in the target tunnel model 15 .

[0039] Among them, the first section 1 is adjacent to the second section 2.

[0040] It should be noted that the sudden section of the tunnel can be a sudden section of the tunnel cross section, or a sudden section of the structure cross connection.

[0041] In one embodiment, upon receiving an instruction to perform transition processing on a target section mutation segment in the target tunnel model 15 , a first section 1 and a second section 2 corresponding to the target mutation segment in the target tunnel model 15 are determined according to parameter information of the target tunnel model 15 .

[0042] In an example, the above-mentioned instruction may be an instruction input by a user through a terminal device, and the instruction may include location information of the mutation segment.

[0043] In another embodiment of the present disclosure, the processing range can also be determined according to the start mileage and end mileage input by the user. All cross-section mutation positions within the processing range are searched and determined according to the tunnel name, route name, start and end mileage.

[0044] Step 102 , obtaining first parameter information of the first section 1 and second parameter information of the second section 2 .

[0045] In one embodiment, the first parameter information and the second parameter information may both include initial support cross-section information and secondary lining cross-section information.

[0046] Step 103: Determine the association relationship between the first section 1 and the second section 2 according to the first parameter information and the second parameter information.

[0047] Among them, the association relationship includes size relationship, offset relationship and primary and secondary relationship.

[0048] In some embodiments of the present disclosure, step 103 may specifically include the following steps:

[0049] Step a1: Obtain a first model type in the first parameter information and a second model type in the second parameter information.

[0050] In one embodiment, the above type may be a tunnel main cave model 11 or an auxiliary cave model 12 .

[0051] Step a2: for the first model type and the second model type, when one model type is a tunnel main cavern and the other model type is an auxiliary cavern, determining the association relationship as a primary and secondary relationship.

[0052] It can be understood that, when one of the models is the tunnel main cave model 11 and the other model is the auxiliary cave model 12, the association relationship between the first model type and the second model type can be determined as a primary-secondary relationship.

[0053] Step a3, obtaining the first section 1 region coordinates in the first parameter information and the second section 2 region coordinates in the second parameter information.

[0054] Step a4, determining whether the association relationship is a size relationship or an offset relationship according to the coordinates of the first section 1 region and the coordinates of the second section 2 region.

[0055] It is understandable that if Figure 2 , Figure 3 As shown, when the association relationship is a size relationship, only one side needs to use a blocking wall for the area where the first section 1 and the second section 2 do not overlap, that is, the mutation area is blocked with a blocking wall; when the association relationship is an offset relationship, there are mutation areas on both sides that do not overlap the first section 1 and the second section 2, and both need to be blocked with a blocking wall. Therefore, different processing methods are required for different association relationships.

[0056] In some embodiments of the present disclosure, step a4 may specifically include the following steps:

[0057] Step a41, generating a first minimum bounding box based on the first section area coordinates, and generating a second minimum bounding box based on the second section area coordinates.

[0058] It can be understood that the first minimum bounding box can be obtained in the following manner: obtain the maximum horizontal coordinate A1, the maximum vertical coordinate B1, the minimum horizontal coordinate a1 and the minimum vertical coordinate b1 in the area of ​​the first section 1, and use (A1, B1), (a1, b1), (A1, b1), (a1, B1) as the four vertex coordinates of the first minimum bounding box to obtain the area coordinates of the first minimum bounding box; similarly, obtain the maximum horizontal coordinate A2, the maximum vertical coordinate B2, the minimum horizontal coordinate a2 and the minimum vertical coordinate b2 in the area of ​​the second section 2, and use (A2, B2), (a2, b2), (A2, b2), (a2, B2) as the four vertex coordinates of the second minimum bounding box to obtain the area coordinates of the second minimum bounding box.

[0059] In some embodiments, when there is a gap between the first cross-section and the second cross-section, a first plane can be determined between the first cross-section and the second cross-section, the first cross-section and the second cross-section can be projected onto the first plane, and the determination operation of the first minimum bounding box and the second minimum bounding box can be completed based on the projection result.

[0060] Step a42: for the first minimum bounding box and the second minimum bounding box, when one of the bounding boxes contains the other bounding box, determine that the association relationship is a size relationship.

[0061] Step a43: when a part of the area of ​​one bounding box overlaps with that of the other bounding box, determine that the association relationship is an offset relationship.

[0062] It can be understood that determining the association relationship based on the minimum bounding box can improve the accuracy of the judgment result.

[0063] Step 104, according to the association relationship, a processing method corresponding to the association relationship is selected to perform connection processing on the first section 1 and the second section 2 to obtain a target section mutation segment after the connection processing.

[0064] In some embodiments, a plugging wall model can be generated at corresponding positions of the first section 1 and the second section 2, so as to achieve connection between the first section 1 and the second section 2, and block the non-overlapping area between the first section 1 and the second section 2.

[0065] In some embodiments of the present disclosure, step 104 may specifically include the following steps:

[0066] Step b1, when the association relationship is a size relationship, determine the first non-overlapping area 3 corresponding to the first section 1 and the second section 2, determine the first non-overlapping area 3 as the target non-overlapping area, and perform the following plugging wall generation operation on the first non-overlapping area 3 to complete the connection processing.

[0067] like Figure 2 As shown, when the correlation relationship is a size relationship, there is a non-overlapping area only on one side of the tunnel model in the mutation section.

[0068] In one embodiment, when the association relationship is a size relationship, the first non-overlapping area 3 corresponding to the first section 1 and the second section 2 is determined, and the first non-overlapping area 3 is determined as the target non-overlapping area. The following steps b2 to b5 of the plugging wall generation operation are performed for the target non-overlapping area to complete the connection processing.

[0069] Step b2, determining the section to which the target non-overlapping area belongs.

[0070] The corresponding section is the first section 1 or the second section 2.

[0071] In one embodiment, the existence of the first non-overlapping region 3 indicates that the area of ​​one cross section is larger than the area of ​​the other cross section, and the cross section to which the first non-overlapping region 3 belongs is the cross section with the larger cross section area.

[0072] Step b3, generating a secondary lining model 7 of the plugging wall according to the secondary lining outer contour of the corresponding section and the secondary lining inner contour of another section.

[0073] Among them, Figure 4 As shown, the secondary lining model 7 of the plugging wall is connected between the first section 1 and the second section 2, and the other section is the section other than the section belonging to the first section 1 and the second section 2.

[0074] It should be noted that the three-dimensional model of the tunnel usually includes an initial support model 6 and a secondary lining model 7. The initial support model is arranged outside the secondary lining model 7. Therefore, it is necessary to generate the secondary lining model 7 of the plugging wall and the initial support model of the plugging wall separately.

[0075] Step b4, generating a first initial support model 13 of the plugging wall on a side close to the corresponding section according to the initial support outer contour of the corresponding section and the initial support inner contour of another section.

[0076] Step b5, generating a second initial support model 14 of the plugging wall on the side close to the other section according to the initial support outer contour of the section and the initial support outer contour of the other section.

[0077] It should be noted that, for the initial support model of the pier wall, a first initial support model 13 and a second initial support model 14 need to be set to ensure the stability of the entire pier wall.

[0078] In some embodiments of the present disclosure, step 104 may specifically include the following steps:

[0079] When the association relationship is an offset relationship, the second non-overlapping area 4 and the third non-overlapping area 5 corresponding to the first section 1 and the second section 2 are determined, and the second non-overlapping area 4 and the third non-overlapping area 5 are respectively determined as target non-overlapping areas, and the target non-overlapping area corresponding to the first non-overlapping area 3 and the target non-overlapping area corresponding to the second non-overlapping area 4 are respectively subjected to plugging wall generation operations to complete the connection processing.

[0080] It can be understood that, as shown in Figure 3, compared with the case where the association relationship is a size relationship, the difference between the case where the association relationship is an offset relationship is that there are two non-overlapping areas, namely the second non-overlapping area 4 and the third non-overlapping area 5. In this case, the above-mentioned plugging wall generation operation can be performed for each non-overlapping area separately to complete the connection processing.

[0081] In some embodiments of the present disclosure, Figure 5 As shown, when the association relationship is a size relationship or an offset relationship, the method may further include the following steps:

[0082] Step c1, obtaining a preset cable trough cutting length.

[0083] It is understandable that if Figure 4 As shown, since there is a non-overlapping area between the two sections, that is, there is a mutation area, the internal cable trough also has a position mutation. Therefore, it is necessary to cut off a part of the cable trough corresponding to the section belonging to the non-overlapping area so that the two cable troughs with mutations can be smoothly connected together.

[0084] Step c2, cutting the first cable trough model 8 according to the cutting length of the cable trough to obtain the cut first cable trough model 8.

[0085] Among them, the first cable trough model 8 is the cable trough model corresponding to the corresponding section.

[0086] Step c3, respectively determining the first section to be connected of the cut first cable trough model 8 and the second section to be connected of the second cable trough model 9.

[0087] The second cable trough model 9 is a cable trough model corresponding to another section.

[0088] Step c4, performing three-dimensional lofting processing according to the first section to be connected and the second section to be connected, to obtain a cable trough connection body model 10 connected between the first section to be connected and the second section to be connected.

[0089] It can be understood that the first section to be connected and the second section to be connected are of standard size, that is, the size is the same. Therefore, three-dimensional lofting processing can be performed based on the first section to be connected and the second section to be connected to obtain a cable trough connection body model 10 connected between the first section to be connected and the second section to be connected.

[0090] In some embodiments of the present disclosure, Figure 6 , Figure 7 As shown, step 104 may specifically include the following steps:

[0091] Step d1, when the association relationship is a primary-secondary relationship, respectively obtain the cross-sectional profile of the main tunnel corresponding to the first section 1 and the cross-sectional profile of the auxiliary cavern corresponding to the second section 2.

[0092] It can be understood that when the association relationship is a primary-secondary relationship, in order to enable the generated tunnel main hole model 11 to be connected with the auxiliary cavern model 12, it is necessary to cut the tunnel main hole model 11 and the auxiliary cavern model 12 respectively so that the tunnel main hole model 11 and the auxiliary cavern model 12 can be reasonably connected.

[0093] In one example, the cut tunnel main hole model 11 and the auxiliary cavern model 12 are as follows: Figure 5 shown.

[0094] Step d2, splicing the tunnel main cave model 11 and the auxiliary cave model 12.

[0095] In one embodiment, the auxiliary cavern model 12 can be placed at the corresponding position of the tunnel main cavern model 11 according to preset configuration parameters. At this time, some structures of the tunnel main cavern model 11 and the auxiliary cavern model 12 overlap, and these overlapping parts need to be cropped.

[0096] Step d3, stretching the cross-sectional contour of the main tunnel to obtain a first cut-out model, and stretching the cross-sectional contour of the auxiliary cavern to obtain a second cut-out model.

[0097] It can be understood that the cutting body model is used to cut the model to be cut, that is, the model to be cut is cut according to the shape of the cutting body model.

[0098] Step d4, using the first cutting body model to cut the auxiliary cave model 12 to obtain the cut auxiliary cave model 12.

[0099] In one embodiment, the auxiliary cavern model 12 may be cut according to the first cut body model corresponding to the cross-sectional profile of the main tunnel to obtain the cut auxiliary cavern model 12 .

[0100] Step d5, using the second cutting body model to cut the tunnel main hole model 11 to obtain the cut tunnel main hole model 11.

[0101] In one embodiment, the tunnel main hole model 11 can be trimmed according to the second trimming model corresponding to the auxiliary cavern section contour to obtain the trimmed tunnel main hole model 11.

[0102] In one example, the cut tunnel main hole model 11 and the auxiliary cavern model 12 are as follows: Figure 7 shown.

[0103] According to the method for processing a sudden section of a tunnel three-dimensional model proposed in the embodiment of the present disclosure, in response to receiving an instruction to perform transition processing on a sudden section of a target section in a target tunnel model, the first section and the second section corresponding to the target sudden section in the target tunnel model are determined; the first parameter information of the first section and the second parameter information of the second section are obtained; the association relationship between the first section and the second section is determined according to the first parameter information and the second parameter information; according to the association relationship, a processing method corresponding to the association relationship is selected to perform connection processing according to the first section and the second section to obtain the sudden section of the target section after the connection processing. By judging the association relationship between the adjacent first short side and the second section and determining the corresponding connection processing method according to the association relationship, the dependence on manual labor is reduced, the difficulty of connection processing of the sudden section of the section is reduced, and the convenience and processing efficiency of connection processing of the sudden section of the tunnel three-dimensional model are improved.
