Title:
INDOOR LOCATION POSITIONING METHOD USING DEEP LEARNING
Document Type and Number:
WIPO Patent Application WO/2022/092451
Kind Code:
A1
Abstract:
The present invention relates to a technology relating to an indoor location positioning method using deep learning. The indoor location positioning method comprises the steps of: importing a 3D tour comprising a plurality of panorama images; receiving a first perspective image captured by a camera provided in a user terminal; calculating global features relating to the first perspective image and each of the plurality of panorama images included in the 3D tour; selecting a panorama image most similar to the first perspective image by means of the calculated global features; calculating an indoor position corresponding to the position of the camera in the 3D tour by using the features included in the first perspective image and the selected panorama image; and providing the calculated indoor position to the user terminal.
