Problems solved by technology

Although the above-mentioned patent can realize the three-dimensional visualization effect of SVG map data, it relies on Adobe Illusrator (third-party software) to operate the basic elements of production, which means that a lot of manpower is required, and its display content is stored on the server and needs to be loaded using Ajax communication. visual content

Embodiment 1

[0066] This embodiment provides a method for visualizing a WebUI intersection model, as shown in Figure 1, including:

[0067] S1. Predefine the two-dimensional drawing structure of intersection and road section models in SVG format;

[0068] S2. Modularize the structure related to intersections and road sections with basic two-dimensional graphic components;

[0069] S3. An algorithm for creating a two-dimensional drawing structure corresponding to points, lines and planes;

[0070] S4. Based on the created algorithm, the structure related to the intersection of different shapes and road section organization is abstracted;

[0071] S5. Calculating and adjusting the differences of the basic two-dimensional graphic components of different intersections and road sections respectively;

[0072] S6. Use SVG technology to splice different basic two-dimensional graphics components to obtain intersections and road section graphics;

[0073] S7. Create a data structure and an event...

example 1

[0105] Example 1: Y-shaped intersection and intersection, one is different from 3-segment road surface and 4-segment road surface, but the composition attributes of the road surface are the same, such as zebra crossing, lane, stop line, landmark, flower bed, etc., so we can extract the road surface for abstraction , the data structure expression is a Y-shaped intersection, then only three road surfaces with an included angle of 120 degrees need to be combined, and the data structure expression is a crossroad, then only four road surfaces with an included angle of 90 degrees need to be combined. The road surface is abstract, not concrete, and only when the combination is completed can it be realized concretely.

example 2

[0106] Example 2: There are section A, section B, ... n+1 section of the road section, and each section has the same attribute components, such as road signs, landmarks, parking spaces, no parking areas, zebra crossings, etc., so you can use A small road section is abstracted, and the data structure representation has N sections, and then N road sections are formed. The road section is abstract, a complete road section is concrete, and only when the combination is completed can it be realized concretely.

[0107] In step S5, the difference of the basic two-dimensional graphic components of different intersections and road sections is calculated and adjusted respectively.

[0108] Example 1: When the combination of intersections is completed, there is a distance-shaped blank area in the center, and a rectangle is filled for the intersections. For the turntable intersections, there is a polygonal blank area in the center, and the polygons are filled for the turntable intersectio...

Abstract

The invention discloses a WebUI intersection model visualization method and system, and the method comprises the steps: S1, predefining a two-dimensional drawing structure of an SVG format intersection and road section model; s2, carrying out basic two-dimensional graphic component modularization processing on structures related to intersections and road sections; s3, creating an algorithm of a two-dimensional drawing structure corresponding to points, lines and surfaces; s4, abstracting structures related to intersections and road section organizations in different shapes on the basis of the created algorithm; s5, respectively calculating and adjusting the difference of the basic two-dimensional graphic components of different intersections and road sections; s6, splicing different basic two-dimensional graph components by using an SVG technology to obtain intersection and road segment graphs; s7, creating a data structure and an event interface, and enabling the data structure to drive the intersection and the road section to change and the user to obtain an event for operating the interaction message; and S8, using an image / svg + xml data format to serialize the SVG formats of the intersections and the road sections into base64 characters, and generating electronic models of the intersections and the road sections.

Description

technical field [0001] The present invention relates to the technical field of public transportation visualization, in particular to a method and system for WebUI intersection model visualization. Background technique [0002] In the public transportation information application system, information on intersections and road sections is usually stored, displayed, and managed in the form of unit data. When maintaining intersections and road sections, owners are required to know the road conditions, road facilities, etc. Sometimes, the system will also be separated from the site, making maintenance more difficult. [0003] Existing public transport information application systems cannot assist personnel to correctly handle information maintenance of intersections and road sections, and cannot dynamically display and reflect the actual conditions of intersections and road sections before and after maintenance, and are not intuitive. [0004] For example, the patent with the pub...
