[0044] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than 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 the present invention.

[0045] In order to assist designers in route selection, improve work efficiency, and estimate the engineering cost of the comparison line more quickly and accurately, the embodiments of the present invention provide a linear engineering road section division method, device, electronic device and storage medium, which can quickly divide the designed route into various terrain types such as plain areas, hilly areas and mountainous areas, so as to conveniently and quickly calculate the respective proportions of plain areas, hilly areas and mountainous areas, facilitate and quickly estimate the engineering cost of the selected line, realize rapid comparison and optimization of route plans, and also facilitate and quickly estimate the survey workload.

[0046] To facilitate understanding of this embodiment, a linear engineering road section division method disclosed in an embodiment of the present invention is first introduced in detail.

[0047] The embodiment of the present invention provides a method for dividing linear engineering sections, which can be executed by an electronic device with data processing capability; the method can be used to achieve rapid estimation of the engineering cost of the selected line, rapid comparison and optimization of route plans, and rapid estimation of survey workload. Figure 1 The flowchart of a linear engineering road segment division method shown in FIG. 1 mainly includes the following steps S110 to S140:

[0048] Step S110, determining elevation data along the design route according to the linear engineering design route plan.

[0049] The above-mentioned linear engineering design route plan may be a linear engineering design route plan such as a highway or railway, and the linear engineering design route plan may include the line position information of the design route, wherein the line position information includes information such as the specific location and direction of the linear engineering. The line position may be the center line of the road marked on the map for guiding the actual construction, and this center line determines the specific location and width of the road and its relationship with other infrastructure.

[0050] The terrain elevation data on the design route, i.e., the elevation data along the route, can be collected according to the line position information of the design route. Based on this, step S110 can be implemented in the following manner: according to the line position information of the design route in the linear engineering design route plan and the preset terrain line information, the elevation data along the route is determined; wherein the elevation data along the route includes the elevation values ​​of multiple intersections of the design route and the terrain line, and can also include the geographical location information of each intersection.

[0051] The elevation values ​​of adjacent intersections can differ by 1m, 5m or 10m, etc., mainly depending on the elevation difference of the terrain line. The terrain line refers to the contour lines used to represent the undulating shape of the surface on the map, and the terrain line information can be a topographic map. It should be noted that the intersections are not evenly distributed along the design route. In areas where the contour lines are densely distributed (such as mountainous areas), the intersections are densely distributed. Conversely, in areas where the contour lines are sparsely distributed (such as plains), the intersections are sparsely distributed.

[0052] Step S120, determining the elevation values ​​of a plurality of equally spaced points based on the elevation data along the route; wherein the equally spaced points are obtained by dividing the designed route into equally spaced points in the horizontal direction.

[0053] The design route can be divided into equal intervals, and the elevation data of the equally spaced points can be obtained. The elevation data along the route can include the elevation values ​​of multiple intersections of the design route and the terrain line. Based on this, step S120 can be implemented in the following manner: the design route is divided into equal intervals in the horizontal direction according to a preset spacing to obtain multiple equally spaced points; the elevation values ​​of the equally spaced points are determined according to the elevation values ​​of the target intersections corresponding to each equally spaced point in the elevation data along the route; wherein the target intersection corresponding to the equally spaced point is at least one intersection among the multiple intersections that is closest to the equally spaced point in horizontal distance.

[0054] The preset spacing can be selected according to the length of the designed route, and the preset spacing is positively correlated with the route length. Optionally, the preset spacing can be 10 meters, and the distance between adjacent equally spaced points is 10 meters. It should be noted that the embodiment of the present invention does not limit the preset spacing. In other embodiments, the preset spacing can also be other values ​​such as 5m, 20m, etc.

[0055] The horizontal distance between the intersection and the equally spaced point is calculated based on the geographical location information of the two. Considering that the equally spaced points do not necessarily correspond to the intersection, in a possible implementation, when determining the elevation value of the equally spaced point, it is possible to first determine whether there is a first intersection whose horizontal distance from the equally spaced point is 0, that is, to determine whether there is a first intersection with the same geographical location as the equally spaced point; if so, determine the first intersection as the target intersection corresponding to the equally spaced point, and determine the elevation value of the target intersection as the elevation value of the equally spaced point; if not, obtain the second intersection located on both sides of the equally spaced point and with the closest horizontal distance to the equally spaced point, determine the two second intersections as the target intersection corresponding to the equally spaced point, and based on the elevation values ​​and geographical location information of the two target intersections and the geographical location information of the equally spaced point, calculate the elevation value of the equally spaced point according to the distance difference method.

[0056] Step S130, determining the elevation values ​​of the boundary points corresponding to the preset multiple terrain types according to the distribution of the elevation values ​​of the equally spaced points.

[0057] A variety of terrain types can be selected according to actual needs. Optionally, the multiple terrain types may include plains, hills and mountains. The distribution of the elevation values ​​of each equally spaced point may include the size change of the elevation values ​​of each equally spaced point. In order to facilitate the extraction of the distribution of the elevation values ​​of each equally spaced point, the elevation values ​​of each equally spaced point may be arranged according to the size relationship of the elevation values ​​to obtain an arrangement result, and then the elevation value of the demarcation point is determined according to the distribution of the elevation values ​​indicated by the arrangement result.

[0058] It should be noted that this embodiment does not limit the arrangement order corresponding to the arrangement result. The elevation values ​​of the equally spaced points can be arranged in order from small to large, or in order from large to small. The arrangement result can indicate the change in the size of the elevation value, so the elevation value of the demarcation point can be determined based on the arrangement result.

[0059] In some possible embodiments, a scatter plot of elevation values ​​may be generated based on the arrangement results, and based on the scatter plot of elevation values, the elevation values ​​of the demarcation points may be determined.

[0060] In a possible implementation, the elevation values ​​of each equally spaced point can be projected into a coordinate system according to the arrangement sequence of the elevation values ​​in the arrangement result to obtain an elevation value scatter plot, and the elevation value of the demarcation point can be determined according to the slope of the elevation value curve corresponding to the elevation value scatter plot. Each data point in the elevation value scatter plot corresponds to an equally spaced point, and the arrangement sequence of the equally spaced point is the arrangement sequence of its elevation value in the arrangement result. The horizontal coordinate of the elevation value scatter plot can be the arrangement sequence of the equally spaced point, and the vertical coordinate is the elevation value. The elevation value curve can be obtained by connecting adjacent points in the elevation value scatter plot and smoothing them. The slope of the elevation value curve can be divided into multiple parts according to the number of terrain types, and the elevation values ​​corresponding to the demarcation points of the adjacent parts are the demarcation point elevation values. For example, when there are three terrain types: plains, hills, and mountains, the slope of the elevation value curve can be divided into three parts, and the elevation values ​​corresponding to the two demarcation points are the demarcation point elevation values.

[0061] In another possible implementation, the elevation values ​​of each equally spaced point can be projected into a coordinate system according to the arrangement sequence numbers of the elevation values ​​in the arrangement results to obtain a scatter plot of elevation values, and the scatter plot of elevation values ​​can be displayed for the user (such as a designer) to select the arrangement sequence number of the dividing point; in response to the user's selection operation on the elevation value scatter plot, the arrangement sequence number of at least one dividing point is obtained, and the elevation value corresponding to the arrangement sequence number is determined as the elevation value of the dividing point.

[0062] In other possible embodiments, taking into account that the difference between adjacent elevation values ​​in the arrangement results can reflect the range of change in the elevation values, based on this, the elevation difference data can be determined according to the arrangement results, and the boundary point elevation value can be determined based on the concentration of the elevation difference data; wherein the elevation difference data is composed of the difference between adjacent elevation values ​​in the arrangement results, and the difference corresponding to the smallest elevation value is 0.

[0063] Optionally, the method for obtaining the above-mentioned elevation difference data is related to the arrangement order corresponding to the arrangement result. Taking the arrangement result as an example, in which the elevation values ​​are arranged in order from small to large, the elevation difference data can be obtained in the following way: for each elevation value in the arrangement result, subtract the previous elevation value from the next elevation value one by one, and finally set the difference corresponding to the first elevation value to 0 to obtain the elevation difference data.

[0064] In a possible implementation, when determining the elevation value of the demarcation point based on the concentration of the elevation difference data, the elevation difference data can be projected into the coordinate system according to the arrangement sequence number of the elevation value in the arrangement result to obtain an elevation difference scatter plot, and the elevation difference scatter plot is displayed for the user to select the arrangement sequence number of the demarcation point; in response to the user's selection operation on the elevation difference scatter plot, the arrangement sequence number of at least one demarcation point is obtained, and the elevation value corresponding to the arrangement sequence number is determined as the demarcation point elevation value. Among them, each data point in the elevation difference scatter plot corresponds to an equally spaced point, and the arrangement sequence number of the equally spaced point is the arrangement sequence number of its elevation value in the arrangement result. The horizontal coordinate of the elevation difference scatter plot can be the arrangement sequence number of the equally spaced point, and the vertical coordinate is the elevation difference (that is, the difference corresponding to the elevation value of the equally spaced point).

[0065] Users can determine the boundary value of the elevation difference data in the coordinate system (i.e., the elevation difference of the dividing point) based on the concentration and dispersion of the scattered data in the coordinate system, as well as the overall distribution characteristics of the data; based on the elevation values ​​corresponding to the boundary values, determine the elevation values ​​of the dividing points of the plains, hilly areas, and mountainous areas. By constructing an elevation difference scatter plot, users can intuitively view the dispersion and distribution characteristics of the elevation difference data, and can quickly determine the dividing points of various terrain types such as plains, hilly areas, and mountainous areas.

[0066] In another possible implementation, when determining the elevation value of the dividing point based on the concentration of the elevation difference data, a clustering algorithm can be used to divide the elevation difference data into multiple sets corresponding to multiple terrain types, and the concentration of data in different sets is different. The arrangement number of at least one dividing point corresponding to each set is obtained, and the elevation value corresponding to the arrangement number is determined as the elevation value of the dividing point.

[0067] Step S140, dividing the designed route into sections according to the elevation values ​​of the dividing points to obtain a section division result, which includes a plurality of sections obtained by division and their terrain types.

[0068] According to the elevation values ​​of the above-mentioned dividing points, the designed route can be divided into a plurality of sections corresponding to the terrain types, for example, the designed route can be divided into a plain area, a hilly area and a mountainous area.

[0069] Furthermore, based on the results of road section division, the length of the road section under the same terrain type can be statistically obtained, and based on the total road section length corresponding to different terrain types, the proportion of different terrain types can be calculated, thereby providing basic data for the estimation of project cost and survey workload.

[0070] Furthermore, the road segment division result can be displayed visually for the user to modify, and in response to the user's modification operation, the modified road segment division result is obtained.

[0071] The linear engineering road section division method provided by the embodiment of the present invention, after determining the linear engineering design route plan, firstly determines the elevation data along the design route according to the linear engineering design route plan; then determines the elevation values ​​of multiple equally spaced points according to the elevation data along the line; wherein the equally spaced points are obtained by equally spaced division of the design route in the horizontal direction; then determines the elevation values ​​of the demarcation points corresponding to the preset multiple terrain types according to the distribution of the elevation values ​​of each equally spaced point; then divides the design route into sections according to the elevation values ​​of the demarcation points to obtain the section division result, which includes the multiple sections obtained by division and their terrain types. In this way, the design route is automatically divided into multiple terrain types, which can facilitate the comparison of schemes of different design routes, the comparison of engineering costs, and the estimation of survey workload in the early survey and design stage of the route project, thereby providing assistance to designers in line selection and improving the work efficiency of line selection.

[0072] For ease of understanding, the linear engineering road section division method mentioned above is introduced in detail below, taking a preset spacing of 10 meters and multiple terrain types including plains, hills and mountains as an example.

[0073] The embodiment of the present invention can quickly divide the designed route into plain areas, hilly areas and mountainous areas, can quickly realize scheme comparison, grasp the proportion of major structures such as bridges, tunnels, slopes, etc. in different schemes, quickly understand the project cost, and through the proportion of structures, can quickly estimate the workload of drilling, engineering geophysical exploration, etc. required in the survey. Therefore, this method has good applicability in scheme comparison, project cost comparison and survey workload estimation in the early stage survey and design of route engineering.

[0074] See also Figure 2The flowchart of another linear engineering road segment division method shown in FIG. 1 may include the following steps S201 to S206:

[0075] Step S201, collecting terrain elevation data on the designed route.

[0076] The collected terrain elevation data are mainly the elevation values ​​of the intersection of the design route and the terrain line. Figure 3 A schematic diagram of the designed route and elevation data along the route is shown. For easy and intuitive viewing, Figure 3 The elevation data along the route is displayed in the form of a curve, which is obtained by sequentially connecting the intersection points of the design route and the terrain line.

[0077] Step S202, dividing the designed route into equal intervals of 10 meters, and acquiring elevation data of the equally spaced points based on the terrain elevation data.

[0078] Optionally, the elevation data corresponding to the 10m equal spacing is the intersection of the equal spacing line (i.e., a straight line passing through the equal spacing points and perpendicular to the horizontal plane) and the line connecting the terrain elevation data collected in step S201, which can be calculated by the elevation values ​​of the two target intersection points before and after the equal spacing points in the terrain elevation data according to the following distance interpolation formula:

[0079]

[0080] like Figure 4 As shown in the above formula, h and h i 、h i+1 are the elevation values ​​of the intersection of the equally spaced line and the line connecting the two target intersection points, the elevation value of the previous target intersection point, and the elevation value of the next target intersection point; ΔL and L are the horizontal distances between the equally spaced point and the previous target intersection point, and the horizontal distances between the previous and next target intersection points, respectively.

[0081] Step S203, re-sorting the elevation data of equally spaced points from small to large.

[0082] Optionally, the re-ordered data from small to large are projected one by one into the coordinate system. The horizontal coordinate of the coordinate system is the arrangement number of the equally spaced points, and the vertical coordinate is the elevation value, such as Figure 5 shown.

[0083] Step S204, subtracting the previous elevation value from the adjacent next elevation value one by one to form elevation difference data, and setting the first data in the elevation difference data to 0.

[0084] Step S205, construct an elevation difference scatter plot, divide the plain area, hilly area and mountainous area according to the concentration of the elevation difference scatter points, and record the demarcation points. According to the elevation difference of the demarcation point, the corresponding arrangement number can be determined and converted into the elevation value accordingly, that is, the elevation value of the demarcation point is obtained.

[0085] Optionally, the formed elevation difference data can be projected into the coordinate system one by one to form a scatter plot, such as Figure 6 The horizontal axis of the coordinate system is the arrangement number of equally spaced points, and the vertical axis is the elevation difference.

[0086] The elevation difference in the plain area is small, and the elevation difference points are concentrated in a smaller elevation difference interval, and are concentrated in the scatter plot; the elevation difference in the hilly area is large, and the elevation difference points are distributed in a larger elevation difference interval, and the concentration of elevation difference points is less than that in the plain area; the elevation difference points in the mountainous area are more scattered.

[0087] like Figure 6 As shown, the arrangement number corresponding to the boundary point between the plain area and the hilly area obtained in this embodiment is 1669, and the corresponding elevation value is 10.755m; the arrangement number corresponding to the boundary point between the flat hilly area and the mountainous area is 3170, and the corresponding elevation value is 65.55m.

[0088] like Figure 7 As shown, the elevation difference of the dividing point is the boundary value for dividing the plain area, hilly area and mountainous area. By recording the arrangement number of this elevation difference, the corresponding elevation value can be found.

[0089] Step S206, dividing the area along the designed route into plain area, hilly area and mountainous area according to the elevation values ​​of the above-mentioned dividing points.

[0090] like Figure 8 As shown, the designed route can be divided into multiple sections corresponding to the plain area, hilly area and mountainous area through the boundary line between the plain area and the hilly area and the boundary line between the hilly area and the mountainous area.

[0091] The embodiment of the present invention can realize the segmentation of route engineering along the route by combining mathematical statistics with graphics, and provide guidance and technical support for the preliminary survey and design of the route engineering in terms of scheme comparison, survey workload comparison, and engineering cost comparison.
