Embodiment 1

[0048] This embodiment provides a path guidance method, such as figure 1 shown, including the following steps:

[0049]S1: pre-store the identification picture of each entrance / exit on the expressway, and the identification picture is associated with the position coordinates of the corresponding entrance / exit. There are many ways to obtain the logo picture, for example, through information collection in advance, after the dedicated vehicle is equipped with an on-board camera and a GPS positioning module, the actual situation along the line is collected, and the collected information is sent to the background, either by a professional People can intercept and save iconic pictures, and can also directly save pictures corresponding to the coordinates of the entrance / exit.

[0050] S2: According to the location coordinates of the starting point and the destination, the planned route is obtained; this step can be realized through the navigation system and the electronic map functi...

Embodiment 2

[0062] This embodiment provides a path guiding device, such as image 3 shown, including:

[0063] The storage unit 1 pre-stores an identification picture at each entrance / exit on the expressway, and the identification picture is associated with the position coordinates of the corresponding entrance / exit; Acquisition, after the dedicated vehicle is equipped with a vehicle-mounted camera and a GPS positioning module, it collects the actual situation along the line and sends the collected information to the background. Professionals can intercept and save iconic pictures, or directly save them with the entrance / exit location coordinates corresponding to the picture.

[0064] The path planning unit 2 obtains the starting point location coordinates and the destination location coordinates to obtain the planned path; it can be realized through the functions of the navigation system and the electronic map.

[0065] The matching unit 3 acquires the real-time position coordinates d...

Embodiment 3

[0074] This embodiment provides an intelligent terminal, including the path guidance device described in Embodiment 2; the intelligent terminal is any one of a smart phone, a tablet computer, and a vehicle-mounted terminal. It provides users with more diverse application scenarios and better user experience.

Abstract

The invention provides a path leading method and device and an intelligent terminal. The method comprises the steps that identification pictures of all inlets / outlets on a highway are prestored, and real-time position coordinates of a vehicle in the driving process are acquired and matched with a planned path, wherein the identification pictures are associated with position coordinates of the corresponding inlets / outlets; the distance between the real-time position coordinates and the nearest inlet / outlet of the highway is acquired according to the planned path; when the distance is smaller than a preset threshold value, the identification picture associated with the nearest inlet / outlet of the highway is sent to remind a user. Compared with an existing voice reminding technical scheme, the method has the advantages that the identification pictures of the inlets / outlets are directly reminded to the user, the user can obtain information of the inlets / outlets more intuitively, and the mode that the user judges according to the identification pictures of the inlets / outlets achieves the higher accurate rate than the mode of reminding the distance according to voice.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a path guiding method, device and intelligent terminal. Background technique [0002] In the prior art, users often drive in unfamiliar areas. On normal roads, you may miss the right entrance or exit on a highway. As a result, situations such as going the wrong way, wasting more time, and spending more money have occurred from time to time. [0003] Although, in-vehicle navigation technology and navigation applications in other smart terminals are relatively common, and can provide users with route guidance on unfamiliar road sections. However, the existing navigation technology generally only adopts the map form to display, and prompts the user with a voice to tell which route to follow after how many meters the distance is. This reminder method is not intuitive for users in an unfamiliar environment. For adjacent intersections that are relatively close or...
