Problems solved by technology

[0002] In the existing navigation animation technology, the map data needs to be reloaded every time the animation is executed, which leads to a CPU usage rate of more than 70% and a relatively large power consumption
In the real navigation process, the moving speed of the map displayed on the current screen corresponding to the user's actual traveling speed is very slow compared to the current screen map. The position on the map displayed on the current screen will not exceed the range of the map displayed on the current screen, and the loading of map data is still frequent, wasting computing resources

Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] figure 1 It is a flow chart of the map loading method for navigation provided according to the present invention.

[0037] according to figure 1 , the map loading method for navigation includes:

[0038] In step S101, the navigation map is displayed in real time in an animation manner.

[0039] For animations displayed on the map, please refer to figure 2 , figure 2 A schematic diagram showing a navigation animation according to an embodiment of the present invention. Such as figure 2 , shows a self-driving navigation route from "Zhongguancun" to "Xizhimen Subway Station", and Danling Street, Haidian South Road, and Shuangyushu North Road are displayed near the route. During the navigation process, the animation is represented by enlargem...

Abstract

The invention discloses a map loading method and a map loading apparatus for navigation. The map loading method comprises: displaying a navigation map in real time through a cartoon manner; pre-loading undisplayed map data surrounding a current screen displayed map based on the current screen displayed map; utilizing the pre-loaded map data to generate subsequently-displayed cartoon images for navigation; and reloading map data if the pre-loaded map data is not enough to generate the subsequent cartoon images. The method and the apparatus are capable of effectively improving the navigation experience of a user.

Description

technical field [0001] The invention relates to the field of map navigation, in particular to a method and a system device for optimizing animation performance in a navigation process for map loading for navigation. Background technique [0002] In the existing navigation animation technology, the map data needs to be reloaded every time the animation is executed, which leads to a CPU usage rate of more than 70% and a large power consumption. In the real navigation process, the moving speed of the map displayed on the current screen corresponding to the user's actual traveling speed is very slow compared to the current screen map. The position on the map displayed on the current screen will not exceed the scope of the map displayed on the current screen, and the loading of map data is still carried out frequently, which wastes computing resources. Contents of the invention [0003] One of the technical problems solved by the invention is to improve the efficiency of map l...
