Abstract
Provided is a method of simultaneous localization and mapping (SLAM), the method including obtaining a structure of a current image frame, obtaining a structure re-identification constraint based on the structure of the current image frame, and obtaining a SLAM result based on the structure re-identification constraint. By introducing the structure re-identification constraint in a bundle adjustment process to obtain the SLAM result, error accumulation may be more easily controlled, and accuracy and robustness in obtaining the SLAM result may be improved.
