Problems solved by technology

[0003] Usually, there is more than one route between a starting point and a destination. In the prior art, the navigation only displays one of the routes for the user, and cannot display various routes at the same time, nor can it provide the user with road condition information.
[0004] In this case, the user cannot obtain the information of multiple routes, nor can they compare each route, which is not conducive to the user to grasp the route information and choose a fast travel route

Embodiment 1

[0024] figure 1 It is a flow chart of a navigation information label layout method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the navigation client provides navigation for users. This method can be configured by the navigation information label layout device in the client To execute, specifically include the following steps:

[0025] Step 110, receiving the route information of the default route and the route information of at least one alternative route sent by the server.

[0026] Wherein, before receiving the route information of the default route and the route information of at least one alternative route sent by the server, the client sends the starting point and destination input by the user to the server, and the starting point may be the user's current location obtained by the client . The server plans a navigation route for the user based on the received starting point and destination. If there is more tha...

Embodiment 2

[0035] figure 2 It is a flowchart of a navigation information label layout method provided by Embodiment 2 of the present invention. On the basis of the above technical solution, the navigation information label layout method further includes:

[0036] Step 210, determine the position of the leading line between the associated information label and its corresponding route, and the positions of the leading lines do not intersect each other.

[0037] Among them, in order to clarify the corresponding relationship between the associated information label and the alternative route, the associated information label and the alternative route are connected by a lead, and the lead is connected from the center of the associated information label to the alternative route. When the number of associated information labels is more than one , the positions of the leads do not intersect each other.

[0038] Step 220 , while displaying the default route, at least one candidate route and its ...

Embodiment 3

[0043] image 3 It is a flowchart of a navigation information label layout method provided by Embodiment 3 of the present invention. On the basis of the above technical solution, in the navigation information label layout method, determining the label display position according to at least one associated information label includes:

[0044] Step 310 , according to the text content in the associated information tag, determine the pixel width and pixel height of the area occupied by the associated information tag.

[0045] Among them, after comparing the route information of the default route with the route information of each alternative route, determine the text content in each associated information label, and further determine in the navigation page displayed by the client, each associated information label The width and height in pixels of the occupied area.

[0046] Step 320, converting the pixel width and pixel height of the associated information label into Mercator val...

Abstract

The present invention discloses a navigation information label layout method and device. The method is as below: receiving route information of a default route information and route information of at least one alternative route sent by a server; according to the route information, generating associated information labels of the alternative route relative to the default route; determining the label display position according to at least one associated information label, wherein the display position of the label do not overlap with the display positions of the default route and the alternative route, and when the number of label is more than one, the label display positions do not overlap with each other; and displaying the default route, at least one alternative route and corresponding associated information label. The invention can display multiple routes and route-associated information for users, and helps users compare multiple routes in order to select a convenient route to travel.

Description

technical field [0001] Embodiments of the present invention relate to navigation information display technology, in particular to a navigation information label layout method and device. Background technique [0002] Nowadays, people often use navigation to plan routes when driving, and choose faster routes to reduce the time to reach their destinations. [0003] Usually, there is more than one route between a starting point and a destination. In the prior art, the navigation only displays one of the routes for the user, and cannot display various routes at the same time, nor can it provide the user with road condition information. [0004] In this case, the user cannot obtain the information of multiple routes, and cannot compare the various routes, which is not conducive for the user to grasp the route information and choose a quick travel route. Contents of the invention [0005] The present invention provides a navigation information label layout method and device, so...
