Embodiment Construction

[0007] The rendering method of the present invention can be applied to the technology in the field of generating traffic guidance maps, for example, driving guidance maps, parking guidance maps, etc. in the traffic guidance maps, and the invention can be applied to coloring and rendering of the published traffic guidance maps.

[0008] For example, the accompanying drawings figure 2 The drawn traffic guidance map template picture shown is referred to as the map template picture M hereinafter. First load the map template image M, assuming that the map template image M is spliced ​​by ten road sections, the color value of the map template image M corresponding to these ten road sections is absolutely unique, and the unique color value is set to α.

[0009] The following is the loop process, which is divided into three layers of loops, and the three layers of loops are nested loops.

[0010] The first layer of loop: loop all the road sections in the map template picture M, beca...

Abstract

The invention relates to a traffic guidance map rendering method. The rendering method comprises the steps of performing data binding and re-coloring rendering according to a color value (RGB) of a map template picture. Each road is formed by splicing a plurality of road sections, and the color value (RGB) on the traffic guidance map template corresponding to each road section is absolutely unique. According to the method, various complex traffic road graphs can be rendered; the limitation by the actual road shape is avoided; a designer can fully and efficiently design the map in the early stage; a traffic guidance map template is designed in an earlier stage; after road section acquisition data and a map template road section color value (RGB) are successfully bound; the map is randomly modified in the later period, the release result of the guidance map is not influenced, the workload of redrawing the road section bound with the traffic guidance map can be reduced, the use efficiencyof the traffic guidance map template is improved, and meanwhile, the accuracy of traffic guidance is also improved.

Description

technical field [0001] The invention relates to the technical field of traffic information processing technology and a rendering method of a traffic guidance map. Background technique [0002] The traditional rendering method of the traffic guidance map is generally to render each entire road after the map template image is drawn. If a certain road section in the middle of the whole road is under construction, it will lead to inaccurate acquisition of road condition data information of a certain road section, resulting in inaccurate guidance information of the traffic guidance map. Contents of the invention [0003] The invention provides a rendering method of a traffic guidance map, which performs data binding and recoloring rendering according to the color value (RGB) of a map template picture. Each road is composed of multiple road segments, and each road segment corresponds to an absolutely unique color value (RGB) on the traffic guidance map template. This method ca...
