Visual Localization Method, Terminal, And Server - A simplified explanation of the abstract
This abstract first appeared for US patent application 18743519 titled 'Visual Localization Method, Terminal, And Server
The disclosure presents methods and devices for visual localization, where a terminal device captures an image of a building and generates a descriptor based on the image. The descriptor includes information about the horizontal viewing angle between two vertical feature lines representing facade intersection lines of the building. The terminal device then matches this descriptor with a preset database to determine the photographing place of the image.
- Terminal device captures image of a building
- Generates descriptor based on the image

Original Abstract Submitted
The disclosure provides example visual localization methods and devices. One method includes that a terminal device obtains an image of a building. The terminal device generates a descriptor based on the image. The descriptor includes information about a horizontal viewing angle between a first vertical feature line and a second vertical feature line in the image. The first vertical feature line indicates a first facade intersection line of the building, and the second vertical feature line indicates a second facade intersection line of the building. The terminal device performs matching in a preset descriptor database based on the descriptor, to obtain localization information of a photographing place of the image.
