Problems solved by technology

[0003] However, after the navigation equipment enters the tunnel or other places without GPS, it is impossible to accurately locate and navigate precisely because it cannot receive GPS signals, and it is impossible to know the exact position in the tunnel. In this case, users are prone to Missed the fork in the tunnel, resulting in a wrong itinerary

Embodiment 1

[0026] figure 1 It is a flow chart of a navigation method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of navigating vehicles. Typically, this method can be applied to scenarios without GPS navigation signals such as tunnels. The method can be executed by a navigation device, and the device can be realized by software and / or hardware, see figure 1 , the method specifically includes the following steps:

[0027] Step 110, if an offline navigation trigger event is detected, the current location information is acquired as the initial location information of the vehicle.

[0028] Wherein, the offline navigation refers to the situation that the navigation software in the navigation device cannot receive the GPS navigation information number, and an offline navigation event will be triggered when the vehicle enters an area without GPS signals. The navigation device may be a device with a navigation function such as a mobile term...

Embodiment 2

[0041] figure 2 It is a flow chart of a navigation method provided by Embodiment 2 of the present invention. The technical solution of this embodiment is based on the above embodiments, and step 120 is further refined. Refer to figure 2 , the method specifically includes the following:

[0042] Step 210, if an offline navigation trigger event is detected, then acquire the current location information as the initial location information of the vehicle.

[0043] Step 220, collect the image information of the driving section within the viewing area at a preset frequency through the image collection module.

[0044] Among them, the image collection module is used to collect the image information of the driving road section within the viewing area. Exemplarily, the image acquisition module may be a camera in a mobile navigation terminal, or a photographing device installed on a vehicle body.

[0045] Exemplarily, if the image acquisition device is a camera in a mobile navigati...

Embodiment 3

[0058] Figure 5 It is a flow chart of a navigation method provided by Embodiment 3 of the present invention. The technical solution of this embodiment is to further refine step 120 on the basis of Embodiment 1. Refer to Figure 5 , the method may specifically include:

[0059] Step 310, if an offline navigation trigger event is detected, obtain the current location information as the initial location information of the vehicle.

[0060] Step 320, collecting acceleration information of the vehicle at preset time intervals through the acceleration sensor.

[0061] Wherein, the acceleration sensor is a sensor capable of measuring acceleration, and the acceleration information of the vehicle can be collected through the acceleration sensor installed on the vehicle body or the acceleration sensor built in the mobile navigation terminal.

[0062] Acceleration of the vehicle is collected through the built-in acceleration sensor in the mobile terminal, without additional hardware i...

Abstract

The invention discloses a navigation method and device, equipment and a medium. The method comprises the following steps: if an offline navigation trigger event is detected, acquiring current positioninformation as initial position information of a vehicle; determining the real-time moving distance of the vehicle according to a first preset strategy and / or a second preset strategy; and determining real-time position information of the vehicle according to the initial position information and the real-time moving distance of the vehicle to position and navigate the vehicle through the real-time position information. According to the technical scheme provided by the embodiment of the invention, the effects of accurate positioning and navigation in a GPS-free scene are achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of navigation, and in particular, to a navigation method, device, equipment and medium. Background technique [0002] GPS satellite navigation is widely used in car navigation. The navigation equipment can be vehicle terminal, portable navigator and mobile terminal. reach the destination. [0003] However, after the navigation device enters the tunnel or other places without GPS, it is impossible to accurately locate and navigate precisely because it cannot receive GPS signals, and it is impossible to know the exact position in the tunnel. In this case, it is easy for users to Missed the fork in the tunnel, resulting in a wrong itinerary. Contents of the invention [0004] The present invention provides a navigation method, device, equipment and medium to realize precise positioning and navigation effects in a scene without GPS. [0005] In a first aspect, an embodiment of the ...
