Embodiment 1

[0052] Embodiment 1: a kind of highway cross section line batch generation method, comprises the following steps:

[0053] Step 1. Collect highway design centerline data and analyze the centerline node sequence; the specific steps are:

[0054] (1) Collect highway design centerline data in DXF format;

[0055] (2) Use the dxflib library to read the highway design centerline data file, and analyze the coordinates (x, y) and convexity parameters (bulge) of each node of the centerline;

[0056] (3) Determine the starting point and starting mileage of the highway design centerline 0 , Sort the nodes according to the start and end order to form a node sequence D s {D s |p i (x i ,y i ,0,bulge i ) ∈ Ds}.

[0057] Such as Figure 5 It is the coordinates of some nodes and their convexity parameters obtained by analyzing the design centerline of a highway. The design centerline length of the example data is 23.5 km, including 5946 nodes.

[0058] Step 2, calculate the mileag...

Abstract

The invention relates to a road cross section line batch generation method, belongs to the technical field of road line design and measurement, and particularly relates to a road cross section line batch generation method. The method comprises the following steps: firstly, collecting and analyzing road design center line data to obtain a node sequence Ds, then calculating a mileage value at each node to obtain a node mileage sequence Ls, and analyzing a cross section mileage parameter file to obtain a mileage parameter set Lc; and calculating coordinates of midpoints, left end points and right end points of section lines at all mileages according to the mileage parameters and the design center lines, finally storing results, and achieving batch rapid generation of the road cross section lines. The method is reasonable in design and has the advantages of being high in automation degree, high in efficiency, good in accuracy, low in cost and the like.

Description

technical field [0001] The invention belongs to the technical field of highway route design and measurement, in particular to a batch generation method for highway cross-section lines. Background technique [0002] In highway route design and survey work, highway cross-section survey plays a very important role in highway construction. The position of the cross section is usually determined according to the mileage value on the center line of the highway design. The extension range of the left and right ends of the cross section has a great relationship with the environment of the location. With the difference of the surrounding environment, the extension range of the two ends also changes accordingly. . [0003] At present, the commonly used methods for generating cross-section lines are mainly realized based on CAD software, but most of the existing software realize batch generation of cross-section lines according to the fixed mileage distance and the extension range of ...
