Original Abstract Submitted

The disclosure provides a method, device and storage medium for back-end optimization of simultaneous localization and mapping. In the method, a target three-dimensional space point is determined in three-dimensional space points of a plurality of key frames located by a simultaneous localization and mapping system. In addition, a reprojection error is determined based on the target three-dimensional space point, and a weight is provided for the reprojection error by preprocessing the maximum parallax corresponding to the target three-dimensional space point, to obtain the relative reprojection error.
