Embodiment 1

[0029] According to an embodiment of the present invention, an embodiment of a lane line display method for navigation is provided.

[0030] Optionally, in this embodiment, the above method for displaying lane lines for navigation can be applied to such as figure 2 In the hardware environment constituted by the server 202 and the terminal 204 as shown. figure 2 It is a schematic diagram of a hardware environment of a lane line display method for navigation according to an embodiment of the present invention. Such as figure 2 As shown, the server 202 is connected to the terminal 204 through a network. The above-mentioned network includes but not limited to: a wide area network, a metropolitan area network or a local area network. The terminal 204 is not limited to a PC, a mobile phone, a tablet computer, and the like. The method for displaying lane lines for navigation in the embodiment of the present invention may be executed by the server 202 , may also be executed by th...

Embodiment 2

[0129] The technical solutions of the present invention will be described below in conjunction with preferred embodiments. In this embodiment, the target geographic location is preferably an intersection, and the penultimate position point and the penultimate position point are the last two shape points on the target route before reaching the intersection.

[0130] The first step, before the target user reaches the next intersection, obtain the coordinates of the last two shape points on the target route to the intersection, that is, the first shape point and the second shape point, the first shape point is the closest to the intersection , the second shape point is adjacent to the first shape point. Wherein, the target route is composed of multiple points, and each point is a shape point.

[0131] In the second step, since two points can determine a straight line, the direction of the straight line is represented by the vector corresponding to the straight line determined by...

Embodiment 3

[0137] The application environment of the embodiment of the present invention may refer to, but is not limited to, the application environment in the foregoing embodiments, which will not be described in detail in this embodiment. An embodiment of the present invention provides an optional specific application for implementing the above method for displaying lane lines for navigation, and a terminal applied to the method for displaying lane lines may be a vehicle navigation device.

[0138] Figure 11 It is a schematic diagram of displaying lane lines in a navigation map according to an embodiment of the present invention. Such as Figure 11As shown, in a three-dimensional scene, the lane line includes a straight arrow for indicating the target user to perform a straight-going operation and a curved arrow for instructing the target user to perform a steering operation. First, simulate the navigation. In the 3D scene, the destination to be reached by the target user is Shenna...

Abstract

The invention discloses a lane line display method and device for navigation. The method comprises the following steps: determining a target geographic position on a navigation map, wherein the target geographic position is a to-be-arrived position of a target user on a preset road; acquiring a first route direction of a target route reaching the target geographic position; judging whether a first position relationship between the first route direction and the preset road meets a preset condition or not; under the circumstance that the first position relationship meets the preset condition, determining a lane line display position of the target geographic position on the navigation map according to the first route direction; and in a three-dimensional scene, displaying the lane line of the target geographic position through the lane line display position. The method and device disclosed by the invention solve the technical problem of low flexibility of displaying the lane line in the prior art.

Description

technical field [0001] The present invention relates to the field of navigation, in particular to a lane line display method and device for navigation. Background technique [0002] At present, in the lane line display of navigation, in most cases, the lane line is fixed somewhere on the interface, for example, fixed at the top position of the client interface, the lane line is not on the map, nor in the 3D scene drawn out. figure 1 It is a schematic diagram of displaying lane lines for navigation according to the related art. Such as figure 1 As shown, the lane lines are displayed at the top of the client interface. The lane lines do not belong to the elements in the map and are not placed on the map for rendering. Therefore, the lane lines will not change with the rotation of the viewing angle and will not be displayed flexibly. , and thus cannot bring an intuitive visual experience to the user. [0003] Aiming at the problem of low flexibility in displaying lane line ...
