Embodiment Construction

[0054] Such as figure 1 Shown is a schematic flow chart of the tunnel-based vehicle navigation method provided by the present invention. Specifically, the vehicle navigation method is applied to a navigation device, the vehicle includes a photographing device, and the vehicle travels in a tunnel. As can be seen from the figure, the vehicle navigation method includes: S1 obtaining the driving speed of the vehicle according to the pictures taken by the shooting device; S2 judging the turning information of the vehicle according to the pictures taken by the shooting device; The speed and the turning information of the vehicle obtained in step S2 determine the position information of the vehicle in the tunnel; S4 judges whether to travel according to the preset route according to the position information of the vehicle, if not, jump to step S5; Plan your route.

[0055] In the vehicle navigation method, before the vehicle enters the tunnel, the geographical position information a...

Abstract

The invention discloses a tunnel-based vehicle navigation method and a device thereof. The vehicle navigation method comprises the following steps: S1, obtaining a running speed of a vehicle according to a picture shot by shooting equipment; S2, judging turning information of the vehicle according to the picture shot by the shooting equipment; S3, judging position information of the vehicle in a tunnel according to the running speed, which is obtained in the step S1, of the vehicle and the turning information, which is obtained in the step S2, of the vehicle; S4, judging whether the vehicle runs according to a preset line or not according to the position information of the vehicle, and if not, performing the step S5; S5, re-planning a line according to the position information of the vehicle. According to the vehicle navigation method, the position information of the vehicle in the tunnel is obtained according to the running speed, the turning information and the like of the vehicle in the tunnel, so as to realizing location of the vehicle in the tunnel; therefore, the vehicle can be located in the tunnel, and convenience is provided for drivers.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a vehicle navigation method and a device thereof. Background technique [0002] Vehicle navigation technology is an important branch of GPS (Global Positioning System, GPS) technology. Its working principle is: the navigation equipment receives the position coordinates transmitted by at least 3 satellites among the 24 GPS satellites around the earth, and the received position coordinates Match the position coordinates recorded in the electronic map stored by itself, so as to determine the exact position of the vehicle equipped with the navigation device in the electronic map. The navigation device can be a vehicle terminal, a portable navigator, a mobile phone terminal, and the like. Based on this, after the user sets the starting point and destination, the navigation device will guide the user according to the calculated navigation route, helping the owner to reach the dest...
