DEVICE POSITIONING METHOD, DEVICE AND SYSTEM

The present application discloses a device positioning method, a device and a system, which relate to the technical field of electronics. and which may achieve the accurate positioning of the spatial pose of a user equipment (UE) on the basis of low-cost, wide-coverage and high-precision visual positioning technology. In the present application, by using a panoramic feature library used to represent panoramic features of multiple objects as a retrieval library, when positioning the UE, consistent features of a horizontal resolution of an image captured by the UE can be extracted, and the panoramic feature library is searched so as to determine panoramic features that match with the horizontal resolution consistent features of the image. Then, the spatial pose of the UE when capturing the image is determined on the basis of the panoramic feature. Device positioning by means of said solution has low costs, wide coverage (for example, the method does not rely on manually designing feature points, does not requir
