Abstract

The invention is applicable to the field of automobile navigation and provides an automobile navigation method and system and an electronic terminal. The method comprises the following steps: recording elemental information in picture files of scalable vector graphics (SVG) as well as incidence relations between the elemental information and lanes of roads in electronic map data; storing the made picture files of the SVG according to the elemental information and the incidence relations; and navigating an automobile of a user according to the incidence relations and the stored picture files of the SVG, wherein the picture files of the SVG are recorded in a layered mode, and each element on each layer has a unique marker. The text information in the pictures of the SVG can be called, and corresponding voice information is broadcast and output to the user. Along with change of distance between the automobile and a branching point, the size and definition of a board for outputting navigation pictures to the user are dynamically adjusted. The user can clearly and accurately master the information of the roads and ambient environments.

Description

technical field [0001] The invention is applicable to the field of car navigation, and in particular relates to a car navigation method, system and electronic terminal. Background technique [0002] Existing navigation systems provide users with navigation based on traditional grid images. These raster images are drawn using relevant professional software, and then associated with navigation data through file numbers. Raster images cannot be enlarged or reduced at will, because different users need to use images of different sizes and styles, and it is necessary to recreate images of different proportions and styles according to the needs of users. [0003] For the information contained in the picture, especially the text information, the navigation system cannot analyze it very well, and must give the user the necessary prompts through other auxiliary methods. For example, software is used to identify the information contained in the picture, and then the information is f...
