Description

Navigation method and terminal device

Technical field

The present invention relates to the field of positioning, and in particular, to a navigation method and a terminal device.

Background technique

With the development of the mobile terminal and the automotive industry, various technologies such as mobile phone built-in electronic maps and car navigation have emerged in an endless stream, bringing convenience to daily life. Portable projectors, that is, projection mobile phones, have also been put on the market, invigorating the life of audio-visual and digital life.

Among the existing products or the disclosed technologies, there are many molding products that focus on electronic navigation. For example, Google Maps, Baidu Maps, E Road Airways, Ren I Tour, etc. After installing the software on the mobile terminal, the user can carry an electronic map query with him or her. You can also open the electronic map for help at any time after the car is installed and navigated.

The current method of using electronic maps is to directly display the map between the departure point and the destination to the pedestrian, and identify the road map. The user needs to comprehensively judge the next direction according to the east, west, north and south. The electronic map can be zoomed in and out. When using it, the user needs to have a basic understanding of the surrounding position, and can distinguish the general direction and combine the street signs.

As shown in Figure 1, the following uses Baidu map as an example. Assume that the user departs from the originating point to the Zhangjiang subway station Zuchongzhi Road Station, the user needs to make three judgments:

1> The default arrow direction is the front of the user. First turn from the starting point to the southeast to Chenhui Road. You need to make the first direction judgment.

2> Confirm the direction of Chenhui Road, you need to judge the direction for the second time.

3> Walk 229 meters along the northeast direction of Chenhui Road. It is necessary to judge the distance. After reaching 229 meters, it is necessary to make a third direction judgment.

Usually, there are three types of pedestrians who cannot judge the orientation: one is the night pedestrian who cannot recognize the position due to the darkness of the night environment; the other is that although walking in the daytime, in the dark environment, it is impossible to identify the pedestrians in the direction; Poor feeling, identify pedestrians with weak orientation.

When a pedestrian is in a dark environment, it is impossible to confirm the north-south direction of the east and west, and it is difficult to directly use the map when the reference object is not visible. Pedestrians with poor sense of direction, because they can't correctly distinguish between north and south, or can't find road signs, they will not know how to go with the electronic navigation map. Therefore, it is difficult to judge the three-way direction in the example of FIG. 1 for the night walker and the walker with a poor sense of direction.

At present, in related technologies and products, car navigation needs to be installed inside the car, which is not applicable to walking pedestrians, and the cost is relatively expensive. Mobile terminal devices can be installed with electronic navigation maps, such as mobile phones, ipads, etc., but the applicability is not strong in dark environments, and limited help for pedestrians with weak sense of direction. In addition, no matter the day or night, when the user is standing on the side of the road and carefully checking, the surrounding traffic situation may be neglected, and there are potential safety hazards.

Embodiment 2

The navigation method of the embodiment of the present invention is further described below in conjunction with actual scenarios.

The navigation method of the embodiment of the present invention includes the following steps.

The first step: the mobile terminal is positioned by GPS. At present, there are many mainstream positioning methods in the market, such as GPS, Galileo, Beidou and other positioning systems based on satellite positioning, and grid systems with base stations or hotspots as backgrounds. The ultimate goal of the technical solution in this embodiment is to introduce the path in real time. The reference positioning is only part of the function in the solution, and navigation is the ultimate goal. For the purpose of fast navigation and positioning, this solution selects the current mainstream GPS positioning.

The second step: using the Baidu map API interface and the compass sensor driver interface to complete the design of the lead road software.

1> The user interface of the mobile terminal can adopt the UI design as shown in FIG. 3. After the user inputs the origin and the destination, the user can query the feasible route map through the Baidu map API interface, and provide various lines for the user to select in the interface. According to the current technology, there are two types of query schemes, and the user can input a query or a language. Audio input query.

2> After the user selects a certain line, the map can be moderately enlarged by clicking the touch screen. The highest magnification of the map is the same as Baidu map. When the user chooses to start the route, the map will be enlarged to the highest multiple. The UI interface clearly identifies the road name of the user at the current location, especially the intersection road name.

3> For the user's forward direction, the lead software calls the compass driver, and after logical analysis, it is clearly marked in the terminal UI with a 1 cm arrow.

4> After the user selects to turn on the projection, the arrow and road name will be projected on the ground, other dark, shaded areas or objects.

5> The user holds the mobile phone and follows the direction of the arrow.

6> The guidance software updates the direction of the arrow and the name of the intersection at the intersection in real time according to the user's direction of travel (including the distance from the user's position to the intersection, and the meter is selected as the single).

7> The projection surface is cancelled after the user chooses to exit the projection. During the projection of the user, the projection effect will be affected only in the following extreme cases: the external illumination is too strong to project, the mobile phone is low or the system is crashing, and the GPS system is abnormal.

Compared with the prior art, the above technical solution fully utilizes the functions of the combination of the compass, the electronic map and the projection, so that the user is in the map while walking, saving the time for the user to judge the orientation and improving the accuracy of the orientation determination. User experience is better and more humane. In the broad sense of the daytime pedestrians at the same time, due to the projection of the enlarged font, especially suitable for the elderly. It also solves the problem that pedestrians ignore the traffic safety and bring hidden dangers when they focus on electronic maps.
