Abstract

The invention discloses a positioning method and device and a storage medium. The method comprises the following steps: determining a first group of positioning constraint parameters at the k-th moment according to inertial sensing measurement information, measured from the (k-1)-th moment to the k-th moment, of a target terminal; determining a 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 a (k-1)-th group of position parameters of the target terminal at the (k-1)-th moment; determining a positioning correction parameter at the k-th moment according to the first group of positioning constraint parameters and the second group of positioning constraint parameters at the k-th moment; and according to the positioning correction parameter at the k-th moment, correcting the k-th group of position estimation parameters to obtain the k-th group of position parameters of the target terminal at the k-th moment. The technical problem of low positioning accuracy is solved, and the method can be applied to the technical fields of maps, navigation, automatic driving, intelligent transportation and the like.

Description

Technical field [0001] The present invention relates to the field of computer, in particular, to a positioning method and apparatus, a storage medium. Background technique [0002] Common satellite positioning techniques, in some scenarios, cannot be positioned or unprecedented, and cannot meet the user's positioning requirements. For example: indoor scenes such as large shopping malls, scenic spots, underground parking lots. A scenario that cannot be positioned or accurately positioned for this satellite, short-range wireless communication technologies such as WiFi, Bluetooth, for example, positioning the mobile terminal by measuring WiFi signal intensity of the mobile terminal. However, the positioning method is single, poor positioning accuracy, and is difficult to provide a continuous positioning output. [0003] There is a problem that the positioning accuracy is less accurate for a scenario where the satellite cannot be positioned or unpredictable. Inventive content [000...
