Abstract

The invention discloses a positioning method, device and storage medium. Wherein, the method includes: according to the inertial sensing measurement information of the target terminal measured from the k-1th moment to the kth moment, determining the first group of positioning constraint parameters at the kth moment; parameters and the k-1th group of position parameters of the target terminal at the k-1th moment, determine the k-th group of position estimation parameters of the target terminal at the k-th moment; according to the first group of positioning constraint parameters and the k-th Two sets of positioning constraint parameters, determine the positioning correction parameters at the kth moment; modify the kth group of position estimation parameters according to the positioning correction parameters at the kth moment, and obtain the kth group of the target terminal at the kth moment positional parameters. The invention solves the technical problem of low positioning accuracy, and can be applied to technical fields such as maps, navigation, automatic driving, and intelligent transportation.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a positioning method and device, and a storage medium. Background technique [0002] Common satellite positioning technology, in some scenarios, cannot locate or accurately locate, and cannot meet the positioning needs of users. For example: indoor scenes such as large shopping malls, scenic spots, and underground parking lots. For scenarios where satellites cannot be positioned or accurately positioned, short-range wireless communication technologies such as WIFI and Bluetooth will be applied. For example, the mobile terminal can be positioned by measuring the WIFI signal strength of the mobile terminal. However, this positioning method has a single mode, poor positioning accuracy, and it is difficult to provide continuous positioning output. [0003] For scenarios where satellites cannot be positioned or cannot be positioned accurately, there is a problem of low positioning a...
