Title:
ENVIRONMENT IDENTIFICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/179281
Kind Code:
A1
Abstract:
An environment identification method and an apparatus. The method comprises: a terminal device captures images in a single environment by means of a plurality of cameras and from a plurality of azimuth angles, wherein the azimuth angle when each camera captures an image is the azimuth angle corresponding to said image, and each azimuth angle is the included angle of a gravity unit vector and a direction vector when each camera captures an image (S700); and the terminal device identifies said single environment according to the images and the azimuth angles corresponding to the images, and obtains an environment identification result (S701). The present method integrates a plurality of images and azimuth angles corresponding to each of the images to perform identification on an environment, and because more comprehensive environment information is obtained, the accuracy of image-based environment identification can be improved, the problem of limitations on an angle of view range and photographing angles when a single camera is identifying an environment is solved, and identification is more accurate and precise.
