Abstract: Provided is a method for simultaneous localization and mapping (SLAM), the method including obtaining a current frame image input through a camera, performing scene recognition on the current frame image to obtain a key frame image having a greatest similarity to the current frame image in a global map, and obtaining a camera pose of the current frame image based on the key frame image.

Abstract: The present disclosure relates to the field of artificial intelligence technology, and to a method of estimating a pose of a device and a related device. The method of estimating a pose of a device includes identifying a similar key frame that is similar to a current frame collected by the device from a key frame set, based on a vector distance between the similar key frame and the current frame; obtaining data-related information between image frames based on a feature matching relationship between the current frame and the similar key frame; and obtaining the pose of the device based on the data-related information.
