Method and device for detecting abnormal data in map data, equipment and storage medium

The invention discloses a method and device for detecting abnormal data in map data, equipment and a storage medium, and the method comprises the steps: obtaining the data size of map elements according to a preset time interval in a map data production period; calculating the difference between two data volumes of each adjacent time interval to obtain a data volume difference value set; determining the statistical average of the data volume difference value set according to the size of each data volume difference value in the data volume difference value set; determining an offset between a data volume difference value in the data volume difference value set and a statistical average value; the abnormal data in each data volume is determined according to the offset and the preset threshold value, the offset obtained by the abnormal data is larger than the preset threshold value, the abnormal data is determined in the map data manufacturing period, high timeliness is achieved, and the mode of determining the
