Embodiment Construction

[0016] The main realization principles, specific implementation modes and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0017] Such as figure 1 As shown, it is a schematic flow diagram of the navigation data update method proposed in the embodiment of the present invention, and its specific processing flow is as follows:

[0018] Step 11: Divide the collected user trajectory into trajectory sections according to the navigation map.

[0019] The navigation device stores navigation data in multiple areas. In order to facilitate the search of navigation data, the navigation data in the navigation device is generally stored in accordance with navigation frames. Each navigation frame corresponds to a different area. The navigation data in the navigation frame The data is the navigation data of the area corresponding to the navigation map. Fo...

Abstract

The invention discloses a navigation data updating method and device and navigation equipment. The method comprises the following steps of: diving an acquired user track into track road sections according to a navigation sheet, determining the road section correlated with the track road section in the navigation sheet of each track road section, and updating navigation data of the navigation sheet of each track road section according to the topological relation between each track road section and the correlated road section. The technical scheme of the invention embodiment provides a specific realization scheme for integrating the user track into the navigation data through the navigation equipment so as to automatically update the navigation data.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a navigation data updating method, device and navigation equipment. Background technique [0002] With the construction of roads and the increase in the number of urban vehicles, self-driving travel has become the main way of transportation. If you do not know the road or cannot find the destination when traveling, users can use the terminal equipment equipped with navigation software. (hereinafter referred to as navigation device) for road navigation, navigation data is stored in the navigation device, when the user uses the navigation device for road navigation, the navigation device first obtains the user's current location and the destination he wants to reach, and then according to the stored navigation The navigation route that can reach the destination determined by the data is provided to the user, and the user can smoothly reach the destination according to the naviga...
