Embodiment Construction

[0041] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0042] In one or more embodiments, terminal positioning may be implemented based on GPS. However, in scenarios with weak satellite signals such as urban canyons, tall buildings, and intersections, the positioning accuracy of this method is not accurate enough, and the positioning availability is poor.

[0043] In order to solve the above-mentioned technical problems, in one or more embodiments, the satellite visual distribution information reflects whether each satellite is visible to the current position such as a grid unit or a terminal, even in a weak satellite signal scenario, the received satellite signal is compared Even if the satellite signal is weak or cannot be received, accurate satellite visualization information can also be obtained. Therefore, the first satellite visualization distribution information of the terminal can be determined based on the a...

Abstract

The invention discloses a terminal positioning method and device, equipment and a storage medium. The application fields include but are not limited to the fields of maps, navigation, automatic driving, terminal life services and the like. When a terminal needs to be positioned at a certain moment such as a target moment, satellite observation information of the terminal at the target moment is acquired, and first satellite visual distribution information of the terminal is determined based on the satellite observation information. Second satellite visual distribution information of each grid unit in the grid area is obtained, and then the matching degree of the first satellite visual distribution information and the second satellite visual distribution information is determined. A target grid unit which is closer to the real position of the terminal from the plurality of grid units in the grid area is selected according to the matching degree, and the target position of the terminal at the target moment is determined according to the grid position of the target grid unit. According to the invention, the position of the terminal can be accurately positioned, so that the accuracy of positioning precision is improved in a weak satellite signal scene, and the positioning availability is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a terminal positioning method, device, equipment and storage medium. Background technique [0002] With the rapid development of positioning technology, more and more terminals with positioning functions can help users locate the user's current location, that is, locate the location of the terminal, so as to provide users with various location services. [0003] The current way of locating the terminal mainly relies on the implementation of the Global Navigation Satellite System (GPS), that is, to locate the current location of the user through the reception of satellite signals and time information. [0004] However, in many scenarios such as urban canyons, high-rise buildings, intersections and other weak satellite signal scenarios, the positioning accuracy of this method is not accurate enough, and the positioning availability is poor.
