Embodiment 1

[0024] figure 1 It is a schematic flow chart of a navigation processing method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the navigation terminal is determined when the GPS signal is weak or there is no signal. This method can be determined by the navigation terminal. Execute to realize positioning and navigation control during the navigation process. The navigation terminal can be composed of hardware and / or software, and can generally be integrated into a computer device. The computer device can be a smart phone, a personal digital assistant, a vehicle computer, etc. . It should be noted that, in the actual application process, the embodiment of the present invention can also apply the computer equipment with the navigation terminal to the vehicle, so as to locate and navigate the vehicle through the navigation terminal. Specifically include the following steps:

[0025] S101. According to the positioning informa...

Embodiment 2

[0052] Combine below figure 2 , in the navigation processing method according to the embodiment of the present invention, the determination of the information entropy threshold of this navigation according to the positioning information and the acceleration value of the navigation terminal will be specifically described.

[0053] figure 2 It is a schematic flowchart of a process of determining the information entropy threshold of this navigation provided by Embodiment 2 of the present invention.

[0054] Such as figure 2 As shown, the determination of the information entropy threshold of this navigation in the embodiment of the present invention may include the following steps:

[0055] S201. According to the positioning information of the navigation terminal, determine the actual state information of the navigation terminal when the GPS is valid.

[0056] Wherein, the positioning information of the navigation terminal refers to information such as longitude and latitude...

Embodiment 3

[0087] It can be seen from the above analysis that the embodiment of the present invention determines the current state of the navigation terminal based on the information entropy threshold of the local navigation and the current information entropy threshold of the navigation terminal.

[0088] In another implementation scenario of the embodiment of the present invention, when the navigation terminal is in a moving state, according to the positioning information of the navigation terminal, it is judged that the movement track of the navigation terminal has yaw, at this time, this embodiment can trigger the yaw verification event, to verify whether the running track of the navigation terminal is off course, so that when it is determined that the navigation terminal is off course, measures can be taken in time to avoid serious consequences. Combine below image 3 , the above situation of the navigation processing method according to the embodiment of the present invention will ...

Abstract

The embodiment of the invention discloses a navigation processing method, a navigation terminal, a device and a storage medium. The method comprises the steps of: determining an information entropy threshold value of the navigation when the GPS (Global Position System) of a navigation terminal is valid according to the positioning information and the acceleration value of the navigation terminal;determining the current information entropy value when the GPS of the navigation terminal is invalid according to the acceleration value of the navigation terminal; and determining whether the navigation terminal is currently in a motion state or not according to the information entropy threshold value of the navigation and the current information entropy value. The method disclosed by the embodiment of the invention has the beneficial effects that the purpose of determining the state of the navigation terminal through the information entropy value when the GPS signal is weak or lost is achieved, thereby increasing the positioning accuracy and reliability of the navigation terminal and improving the user experience.

Description

technical field [0001] The embodiments of the present invention relate to navigation technologies, and in particular, to a navigation processing method, a navigation terminal, a device, and a storage medium. Background technique [0002] The Global Positioning System (GPS for short) is a system that uses GPS positioning satellites to perform real-time positioning and navigation around the world, and is widely used in the positioning and navigation of objects. [0003] During practical application, it is generally possible to determine whether the navigation terminal is in a moving state or a stationary state according to GPS positioning information. Wherein, the navigation terminal may be any software and / or hardware with a navigation function, such as Baidu map. However, due to the use scenarios of the navigation terminal, which may include tunnels, viaducts, underground parking lots and other environments with weak or no GPS signals, it is impossible to accurately determi...
