Abstract

The invention discloses a positioning method and device, electronic equipment and a storage medium. The method comprises the following steps: determining a first position of target equipment; determining a second mapping position set from the first mapping position set according to the first position; wherein the first mapping position set comprises mapping positions corresponding to a plurality of mapping areas, and each mapping position in the first mapping position set has a corresponding relationship with one mapping area; based on the second mapping position set, determining a mapping area list; each mapping area in the mapping area list has a corresponding relationship with a high-precision map; and based on the high-precision map corresponding to at least one mapping area in the mapping area list, performing visual localization on the image acquired by the target device.

Description

technical field [0001] The present application relates to the technical field of positioning, and in particular to a positioning method and device, electronic equipment, and a storage medium. Background technique [0002] The role of the high-precision map is to visually locate the images collected by the device. wide-area HD Figure 1 It is generally difficult to construct, therefore, it is necessary to divide the wide area (also called a super large area), and construct a high-precision map for each divided area (called a mapping area), thus we can get Multiple high-precision maps corresponding to multiple mapping areas, and then multiple high-precision maps corresponding to multiple mapping areas form a wide-area high-precision map. At present, when using wide-area high-precision maps for visual positioning, there is a problem of low positioning efficiency. Contents of the invention [0003] In order to solve the above technical problems, embodiments of the present ap...
