Mobile robot positioning confidence evaluation method and device and storage medium

The invention discloses a mobile robot positioning confidence assessment method and device and a storage medium, and the method comprises the steps: processing a grid map, and extracting features to obtain a feature container; extracting features of the laser frames to obtain feature data; judging whether the quantity of the feature data exceeds a first preset threshold value or not to obtain a first judgment result; when the first judgment result is yes, performing feature matching on the feature data according to the feature container to obtain a matching result; when the first judgment result is no, correlation matching is carried out, and the positioning precision and the pose confidence coefficient are calculated; judging whether the matching result exceeds a second preset threshold value or not to obtain a second judgment result; and when the second judgment result is yes, the positioning precision and the pose confidence coefficient are calculated according to the matched features. According to the pos
