Document Type and Number:
WIPO Patent Application WO/2023/070870
Kind Code:
A1
Abstract:
An identifier positioning method and apparatus, an electronic device and a computer-readable storage medium, related to the field of image processing technology, and the method comprising: identifying a scene identifier of a scene area in a first scene image so as to obtain a scene identifier position; selecting coordinate points from the first scene image, extracting first feature information corresponding to the coordinate points, and respectively recording the coordinate point positions of the coordinate points; identifying within a second scene image of the scene area an identifier to be tested, so as to obtain the position of the identifier to be tested, and extracting second feature information at the position of the identifier to be tested; searching each of the coordinate points for a target coordinate point where the first feature information and the second feature information match, and, in accordance with the coordinate point position corresponding to the target coordinate point and in accordance with the position of the scene identifier in the scene area, calculating the position in the scene area of the identifier to be tested. Compared with existing large-scene positioning methods depending on expensive external auxiliary equipment, the present method greatly reduces the hardware cost of large-scene user positioning.
