However, in existing technologies, it is often necessary to rely on manual processing to connect and transition the abrupt sections, which is difficult to operate and results in low processing efficiency. Summary of the Invention

[0003] To overcome the problems existing in related technologies, this disclosure provides a method, apparatus and system for processing abrupt changes in a three-dimensional tunnel model.

[0008] Based on the correlation, a processing method corresponding to the correlation is selected to perform connection processing on the first cross section and the second cross section to obtain the target cross section abrupt segment after connection processing.

[0009] According to a second aspect of the present disclosure, a device for processing abrupt changes in a three-dimensional tunnel model is provided, comprising:

[0011] The acquisition unit is used to acquire the first parameter information of the first cross-section and the second parameter information of the second cross-section;

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0032] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0033] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the words “if” and “suppose” as used herein may be interpreted as “when”, “when”, or “in response to a determination”.

[0034] Furthermore, various forms of processes shown in the embodiments of this disclosure can be used to reorder, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this disclosure can be achieved, and no limitation is imposed herein.

[0035] In related technologies, abrupt changes in cross-sections often occur during the generation of a 3D tunnel model. In such cases, it is usually necessary to perform transition processing on the abrupt cross-sections to ensure the integrity of the 3D tunnel model and the continuity of the internal components of the tunnel. However, in existing technologies, it is often necessary to rely on manual processing to connect and transition the abrupt sections, which is difficult to operate and results in low processing efficiency.

[0036] To address the aforementioned issues, this disclosure provides a method, apparatus, and system for processing abrupt changes in a three-dimensional tunnel model. In response to receiving an instruction to perform transition processing on a target cross-section abrupt change segment in the target tunnel model, the method determines the first and second cross-sections corresponding to the target abrupt change segment in the target tunnel model; acquires first parameter information of the first cross-section and second parameter information of the second cross-section; determines the association relationship between the first and second cross-sections based on the first and second parameter information; and selects a processing method corresponding to the association relationship to perform connection processing on the first and second cross-sections, obtaining the target cross-section abrupt change segment after connection processing. By judging the association relationship between adjacent first short sides and second cross-sections and determining the corresponding connection processing method according to the association relationship, the method reduces reliance on manual intervention, lowers the difficulty of connecting cross-section abrupt change segments, and improves the convenience and efficiency of connecting abrupt change segments in a three-dimensional tunnel model.

[0037] Figure 1 This is a flowchart illustrating a method for processing abrupt changes in a three-dimensional tunnel model according to an exemplary embodiment, such as... Figure 1 As shown, it should be noted that the tunnel 3D model abrupt change segment processing method of this disclosure embodiment is applied in the tunnel 3D model abrupt change segment processing device. For example... 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 the abrupt change segment of the target section in the target tunnel model 15, determine the first section 1 and the second section 2 corresponding to the target abrupt change segment in the target tunnel model 15.

[0039] Among them, the first section 1 and the second section 2 are adjacent.

[0040] It should be noted that abrupt changes in a tunnel section can be either abrupt changes in the tunnel cross section or abrupt changes in the structural intersection and connection section.

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

[0042] In one example, the above instruction could be an instruction entered by a user through a terminal device, and the instruction could include the location information of the mutation segment.

[0043] In another embodiment of this disclosure, the processing range can also be determined based on the starting and ending mileage input by the user. All cross-sectional abrupt change locations within the processing range are searched and determined based on the tunnel name, route name, and starting and ending mileage.

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

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

[0046] Step 103: Determine the relationship between the first section 1 and the second section 2 based on the first parameter information and the second parameter information.

[0047] Among them, the relationships include size relationship, offset relationship, and primary-secondary relationship.

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

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

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

[0051] Step a2: For the first model type and the second model type, if one model type is the main tunnel and the other model type is the auxiliary chamber, determine the primary and secondary relationship.

[0052] It is understandable that, given that one model is the main tunnel model 11 and the other is the auxiliary chamber model 12, the relationship between the first model type and the second model type can be determined as a primary-secondary relationship.

[0053] Step a3: Obtain the coordinates of the first section 1 region from the first parameter information and the coordinates of the second section 2 region from the second parameter information.

[0054] Step a4: Determine whether the relationship is a size relationship or an offset relationship based on the coordinates of the first section 1 area and the second section 2 area.

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

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

[0057] Step a41: Generate a first minimum bounding box based on the coordinates of the first cross-section region, and generate a second minimum bounding box based on the coordinates of the second cross-section region.

[0058] Understandably, the first minimum bounding box can be obtained in the following way: obtain the maximum x-coordinate A1, maximum y-coordinate B1, minimum x-coordinate a1, and minimum y-coordinate b1 within the region of the first section 1, and use (A1, B1), (a1, b1), (A1, b1), and (a1, B1) as the coordinates of the four vertices of the first minimum bounding box to obtain the region coordinates of the first minimum bounding box; similarly, obtain the maximum x-coordinate A2, maximum y-coordinate B2, minimum x-coordinate a2, and minimum y-coordinate b2 within the region of the second section 2, and use (A2, B2), (a2, b2), (A2, b2), and (a2, B2) as the coordinates of the four vertices of the second minimum bounding box to obtain the region 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, and the first cross section and the second cross section can be projected onto the first plane. Based on the projection result, the determination of the first minimum bounding box and the second minimum bounding box can be completed.

[0060] Step a42: For the first minimum bounding box and the second minimum bounding box, if one bounding box contains the other bounding box, determine the relationship as a size relationship.

[0061] Step a43: If one bounding box partially overlaps with another bounding box, determine the association relationship as an offset relationship.

[0062] Understandably, determining associations based on the smallest bounding box can improve the accuracy of the judgment results.

[0063] Step 104: Based on the correlation, select the processing method corresponding to the correlation and perform connection processing on the first section 1 and the second section 2 to obtain the target section abrupt change segment after connection processing.

[0064] In some embodiments, a blocking wall model can be generated at the corresponding positions of the first section 1 and the second section 2 to connect the first section 1 and the second section 2, and to block the non-overlapping areas between the first section 1 and the second section 2.

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

[0066] Step b1: When the 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 end-blocking wall generation operation on the first non-overlapping area 3 to complete the connection processing.

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

[0068] In one embodiment, when the 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 are performed to generate the end wall for the target non-overlapping area to complete the connection process.

[0069] Step b2: Determine the cross section to which the non-overlapping target area belongs.

[0070] The section to which it belongs is either section 1 (first section) or section 2 (second section).

[0071] In one embodiment, since there is a first non-overlapping region 3, it means 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: Generate the secondary lining model 7 of the end wall based on the outer contour of the secondary lining of the corresponding section and the inner contour of the secondary lining of another section.

[0073] Among them, such as Figure 4 As shown, the secondary lining model 7 of the end wall is connected between the first section 1 and the second section 2, and the other section is the section other than the section to which it belongs in the first section 1 and the second section 2.

[0074] It should be noted that the tunnel 3D model usually includes an initial support model 6 and a secondary lining model 7. The initial support model is set outside the secondary lining model 7, so it is necessary to generate the secondary lining model 7 of the end wall and the initial support model of the end wall separately.

[0075] Step b4: Based on the outer contour of the initial support of the section and the inner contour of the initial support of another section, generate the first initial support model 13 of the end wall on the side closest to the section.

[0076] Step b5: Based on the initial support outline of the section and the initial support outline of another section, generate a second initial support model 14 for the end wall on the side closer to the other section.

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

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

[0079] When the relationship is an offset relationship, the second non-overlapping region 4 and the third non-overlapping region 5 corresponding to the first section 1 and the second section 2 are determined. The second non-overlapping region 4 and the third non-overlapping region 5 are determined as target non-overlapping regions respectively. The end-blocking wall generation operation is performed on the target non-overlapping region corresponding to the first non-overlapping region 3 and the target non-overlapping region corresponding to the second non-overlapping region 4 respectively to complete the connection processing.

[0080] It is understandable that, as shown in Figure 3, the difference between the relationship of size and the relationship of offset 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 end-wall generation operation can be performed on each non-overlapping area to complete the connection process.

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

[0082] Step c1: Obtain the preset cable trough cutting length.

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

[0084] Step c2: Cut the first cable trough model 8 according to the cable trough cutting length 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 its respective cross section.

[0086] Step c3: Determine the first section to be connected of the first cable trough model 8 and the second section to be connected of the second cable trough model 9 after cutting.

[0087] Among them, the second cable trough model 9 is the cable trough model corresponding to another cross section.

[0088] Step c4: Perform three-dimensional lofting based on the first section to be connected and the second section to be connected to obtain the cable trough connection model 10 connected between the first section to be connected and the second section to be connected.

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

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

[0091] Step d1: Under the condition of primary and secondary relationship, obtain the tunnel main tunnel profile corresponding to the first section 1 and the auxiliary tunnel profile corresponding to the second section 2.

[0092] Understandably, when the relationship is primary and secondary, in order to connect the generated main tunnel model 11 and auxiliary tunnel model 12, it is necessary to trim the main tunnel model 11 and auxiliary tunnel model 12 respectively, so that the main tunnel model 11 and auxiliary tunnel model 12 can be reasonably connected.

[0093] In one example, the trimmed tunnel main tunnel model 11 and auxiliary chamber model 12 are as follows: Figure 5 As shown.

[0094] Step d2: Assemble the main tunnel model 11 and the auxiliary tunnel model 12.

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

[0096] Step d3 involves stretching the profile of the main tunnel section to obtain the first cut body model, and stretching the profile of the auxiliary tunnel section to obtain the second cut body model.

[0097] It is understandable that the clipping body model is used to clip the model to be clipped, that is, to clip the model to be clipped according to the shape of the clipping body model.

[0098] Step d4: The auxiliary cavern model 12 is cut using the first cut body model to obtain the cut auxiliary cavern model 12.

[0099] In one embodiment, the auxiliary chamber model 12 can be trimmed according to the first trimming body model corresponding to the cross-sectional outline of the main tunnel to obtain the trimmed auxiliary chamber model 12.

[0100] Step d5: The tunnel main tunnel model 11 is trimmed using the second trimming model to obtain the trimmed tunnel main tunnel model 11.

[0101] In one embodiment, the tunnel main tunnel model 11 can be trimmed according to the second trimmed body model corresponding to the cross-sectional profile of the auxiliary tunnel to obtain the trimmed tunnel main tunnel model 11.

[0102] In one example, the trimmed tunnel main tunnel model 11 and auxiliary chamber model 12 are as follows: Figure 7 As shown.

[0103] According to the tunnel 3D model abrupt change segment processing method proposed in this disclosure, in response to receiving an instruction to perform transition processing on the target cross-section abrupt change segment in the target tunnel model, the method determines the first and second cross-sections corresponding to the target abrupt change segment in the target tunnel model; obtains the first parameter information of the first cross-section and the second parameter information of the second cross-section; determines the association relationship between the first and second cross-sections based on the first and second parameter information; and selects a processing method corresponding to the association relationship to perform connection processing on the first and second cross-sections, thereby obtaining the target cross-section abrupt change segment after connection processing. By judging the association relationship between adjacent first short sides and second cross-sections and determining the corresponding connection processing method according to the association relationship, the method reduces the dependence on manual labor, lowers the difficulty of connection processing of cross-section abrupt change segments, and improves the convenience and efficiency of connection processing of abrupt change segments in the tunnel 3D model.

[0104] Figure 8 This is a block diagram illustrating a tunnel three-dimensional model abrupt segment processing device according to an exemplary embodiment. (Refer to...) Figure 8 The device includes a first determining unit 801, an acquiring unit 802, a second determining unit 803, and a selecting unit 804.

[0105] The first determining unit 801 is configured to, in response to receiving an instruction to perform transition processing on the abrupt change segment of the target section in the target tunnel model, determine the first section and the second section corresponding to the abrupt change segment in the target tunnel model; the first section and the second section are adjacent.

[0106] The acquisition unit 802 is used to acquire the first parameter information of the first cross section and the second parameter information of the second cross section;

[0107] The second determining unit 803 is used to determine the relationship between the first section and the second section based on the first parameter information and the second parameter information; the relationship includes size relationship, offset relationship and primary-secondary relationship;

[0108] Unit 804 is selected to select the corresponding processing method based on the association relationship and perform connection processing based on the first section and the second section to obtain the target section abrupt segment after connection processing.

[0110] Obtain the first model type from the first parameter information and the second model type from the second parameter information;

[0111] For the first model type and the second model type, if one model type is the main tunnel and the other model type is the auxiliary chamber, determine the primary and secondary relationship.

[0112] Obtain the coordinates of the first cross-sectional area from the first parameter information and the coordinates of the second cross-sectional area from the second parameter information;

[0113] The relationship between the two sections is determined by the coordinates of the first and second cross-section areas; whether it is a size relationship or an offset relationship.

[0115] A first minimum bounding box is generated based on the coordinates of the first cross-section region, and a second minimum bounding box is generated based on the coordinates of the second cross-section region.

[0116] For the first minimum bounding box and the second minimum bounding box, if one bounding box contains the other bounding box, the relationship is determined to be a size relationship;

[0117] If one bounding box partially overlaps with another bounding box, the association relationship is determined to be an offset relationship.

Perform the following end-blocking wall generation operation on the first non-overlapping area to complete the connection process.

[0120] Determine the cross section to which the non-overlapping area of ​​the target belongs; the cross section may be either the first cross section or the second cross section.

[0121] The secondary lining model of the end cap wall is generated based on the outer contour of the secondary lining of the corresponding section and the inner contour of the secondary lining of the other section; the secondary lining model of the end cap wall is connected between the first section and the second section; the other section is the section other than the corresponding section in the first section and the second section.

[0122] Based on the outer contour of the initial support of the section and the inner contour of the initial support of another section, generate the first initial support model of the end wall on the side closest to the section.

[0123] Based on the initial support outline of the section and the initial support outline of another section, a second initial support model for the end cap wall is generated on the side closer to the other section.

[0124] In some embodiments of this disclosure, the selection unit 804 can be specifically used to: determine the second non-overlapping area and the third non-overlapping area corresponding to the first section and the second section when the association relationship is an offset relationship; determine the second non-overlapping area and the third non-overlapping area as target non-overlapping areas respectively; and perform a wall-blocking operation on the target non-overlapping area corresponding to the first non-overlapping area and the target non-overlapping area corresponding to the second non-overlapping area respectively to complete the connection processing.

[0129] The lofting unit is used to perform three-dimensional lofting processing based on the first section to be connected and the second section to be connected, so as to obtain the cable trough connection model connected between the first section to be connected and the second section to be connected.

[0130] In some embodiments of this disclosure, the selection unit 804 may specifically be used for:
