Title:
MULTI-TYPE MAP-BASED FUSION POSITIONING METHOD AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/116327
Kind Code:
A1
Abstract:
A multi-type map-based fusion positioning method, comprising: obtaining a target image to be positioned; acquiring a target position where the target image is captured; determining target map quality of a map located at the target position in a map database composed of a plurality of different types of map data; determining a target positioning mode from a plurality of different preset positioning modes according to the target map quality, the target positioning mode being composed of a basic positioning mode corresponding to the map data contained in the map database; and positioning the target image by using the target positioning mode to obtain 6DOF of the target image. Therefore, when an image is positioned, a proper positioning solution can be selected from a plurality of positioning solutions according to different map quality corresponding to the position of the image, a high-precision and stable positioning effect is realized, the non-perception upgrading transition of map quality in time and space is realized, and the user experience is improved.
