Abstract
The disclosure provides a visual positioning method and apparatus, an electronic device and a computer-readable storage medium. The method includes: generating a semantic graph by semantically identifying collected images; determining description information of each entity through a random walk algorithm in the established semantic graph; determining candidate entities matching each entity in a preset entity map based on the description information; and positioning a collection area of the current image based on an area where the candidate entities are located in the preset entity map. The description information of each entity node constructed with the random walk algorithm not only contains semantic information of the corresponding node, but also local constraint information between semantics.
