Abstract
A processor-implemented method includes obtaining a visual association feature indicating an association between a first image frame and a second image frame and a visual appearance feature indicating the same object appearance in the first image frame and the second image frame, constructing a visual reprojection constraint based on the visual association feature, constructing a visual feature metric constraint based on the visual appearance feature, and performing localization and mapping based on the visual reprojection constraint and the visual feature metric constraint.
