Semantic map post-processing method and device, electronic equipment and storage medium

The embodiment of the invention discloses a semantic map post-processing method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining an initial semantic map, and determining semantic map elements in the initial semantic map, and a semantic element point set and semantic element confidence corresponding to each semantic map element; according to the semantic element point set corresponding to each semantic map element, determining an element chamfering distance between every two semantic map elements, and according to each element chamfering distance, determining an average chamfering distance and a chamfering distance variance; according to the semantic element confidence corresponding to each semantic map element, the chamfering distance of each element, the average chamfering distance and the chamfering distance variance, updating the semantic element confidence corresponding to each semantic map element; and according to the updated confidence of each semanti
