Example Embodiment

[0065] Example 1

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

[0067] S1. The two-dimensional drawing structure of the SVG format intersection and road segment model is predefined;

[0068] S2. Modular processing of basic two-dimensional graphic components for structures related to intersections and road sections;

[0069] S3. An algorithm for creating a two-dimensional drawing structure corresponding to a point, line, and surface;

[0070] S4. Based on the created algorithm, abstract the structure related to the organization of intersections and road sections of different shapes;

[0071] S5. Calculate and adjust the differences of the basic two-dimensional graphics components of different intersections and road sections respectively;

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

[0073] S7. Create...

Example

[0105] Example 1: Y-shaped intersection and intersection, one is composed of 3 sections of road surface and 4 sections of road surface, but the composition attributes of the road surface are the same, such as zebra crossings, lanes, stop lines, landmarks, flower beds, etc., so we can extract the road surface for abstraction , the data structure representation is a Y-shaped intersection, then only 3 roads with an included angle of 120 degrees need to be combined, and the data structure representation is an intersection, only 4 roads with an included angle of 90 degrees need to be combined. The road surface is abstract, not concrete, and only the combination is completed to be concrete.

Example

[0106] Example 2: There are sections A, B,...n+1, and each section has the same attributes, such as street signs, landmarks, parking spaces, no-parking areas, zebra crossings, etc. A small road segment is abstracted, and the data structure is represented by N segments, which constitute N road segments. The road section is abstract, a complete road section is concrete, and only when the combination is completed is the concrete realization.

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

[0108] Example 1: The combination of the intersection is completed, and there is a gap-shaped blank area in the center, then fill the rectangle for the intersection, and at the turntable intersection, there is a polygonal blank area in the center, then fill in the polygon for the turntable intersection, and other intersections are carried out according to their characteristic...

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...
