Abstract

The embodiment of the invention provides a positioning method, a model training method and device and a storage medium. The positioning method comprises the following steps: acquiring more than two positioning candidate points corresponding to the same positioning point; determining a satellite starry sky map corresponding to each positioning candidate point, wherein the satellite starry sky map is used for indicating the visibility of the positioning satellite to the positioning candidate point; determining a building shielding map of each positioning candidate point, wherein the building shielding map is used for indicating the shielding degree of buildings around the positioning candidate points to the positioning satellite; inputting the satellite sky map and the building shielding map of the positioning candidate point into a pre-trained positioning weight prediction model, and predicting a positioning accuracy weight of the positioning candidate point by the model; and obtaining the positioning position of the positioning point based on the positioning accuracy weights of all the positioning candidate points. According to the embodiment, the positioning stability is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of positioning, and in particular, to a positioning method, a model training method, an apparatus, and a storage medium. Background technique [0002] In services such as electronic maps, positioning is the basis for implementing location-related services or services, among which, the positioning technology based on the Global Navigation Satellite System (GNSS) is the most common and widely used. [0003] However, in the urban environment, there are problems such as multi-path transmission, Non Light-of-Sight (NLOS) and so on. Therefore, based on the GNSS positioning technology, the obtained positioning position of the object to be located is the same as that of the object to be located in reality. The actual location in the world is prone to inconsistencies. [0004] In order to solve the above problems and improve the positioning accuracy (the higher the positioning accuracy, the sma...
