Embodiment Construction

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used Limit the invention.

[0025] The steps of a custom road data generation method provided by the present invention are as follows figure 1 As shown, it specifically includes the following steps:

[0026] Step 1: When the vehicle is driving on a road without road data for the first time, collect the road trajectory and generate a trajectory signal file.

[0027] Step 2: Read the track signal file to obtain a continuous track point sequence; among them, one track signal file corresponds to a custom road.

[0028] Step 3: Read a track point in sequence according to the track point sequence, and determine whether the track point ...

Abstract

The invention discloses a customized road data generating method and device. The method comprises the following steps: reading acquired a tracing point sequence without road data; dividing tracing points into initial points, end points and middle points; respectively treating the initial points, the end points and the middle points according to the time and space relation between the tracing points and the relation between the tracing points and existing road data to generate a customized road connection relation; and giving a customized road grade for the road data generated with the customized road connection relation. By the method and device, a navigation system can automatically load the customized road data, navigation functions of path programming, guiding, displaying and the like are fulfilled, and therefore, real-time updating of map data is realized.

Description

Technical field [0001] The invention relates to the field of navigation devices, in particular to a method and device for generating custom road data for navigation devices. Background technique [0002] The car navigation system is installed on the vehicle to provide drivers with navigation and guidance services. It can realize real-time positioning, destination retrieval, route planning, screen and voice guidance to help drivers reach their destination accurately and quickly. The realization method of the navigation device is to realize the navigation function by combining the navigation related algorithms on the pre-compiled map data, and the map data is the basis of the navigation system. [0003] The map data update of the existing navigation system has a certain cycle, ranging from one quarter to one year, and the update is not timely. On this basis, my country is currently in a period of rapid development of infrastructure construction. Many new roads are often built during...
