Landmark positioning method and device, computer equipment and storage medium

Abstract

The invention particularly relates to a landmark positioning method and a device, computer equipment and a storage medium. The method comprises the steps of acquiring a to-be-recognized image corresponding to an automobile external scene; obtaining landmark position information and depth-of-field information of a landmark in the to-be-identified image; obtaining coordinate information of the landmark; searching landmark description information corresponding to the landmark in a preset landmark database according to the coordinate information of the landmark; and obtaining user description information corresponding to the positioning target location, searching the positioning target location in the landmark according to the user description information and the landmark description information, and obtaining coordinate information of the positioning target location. According to the method, the current external image is obtained through the automobile camera; the landmark in the image isidentified, the destination landmark in the landmark is determined through the description information of the user, destination positioning is carried out, the target location positioning precision is improved through the description of the target location by the user, the positioning error probability can be effectively reduced, and the landmark positioning efficiency is improved.

Description

Technical field [0001] This application relates to the field of computer technology, in particular to a landmark positioning method, device, computer equipment and storage medium. Background technique [0002] Positioning refers to determining the position. With the development of science and technology, positioning systems such as GPS (Global Positioning System, Global Positioning System) have emerged, through which the current location of the user can be accurately determined. [0003] However, when locating the user's target location in the vehicle, if the target location is a street, the street address is long and complicated. This leads to the need to spend the street address regardless of whether it is using touch screens, buttons and dials, or voice input. It takes a long time to be entered into the car’s navigation system, and roads with the same name are easily confused: multiple addresses in the same area may use the same name, which means that the driver or car may choo...
