Bad data correction method and device, storage medium and electronic equipment

Abstract

The invention discloses a bad data correction method and device, a storage medium and electronic equipment. The method comprises the following steps: acquiring an initial suspicious measurement set; judging the relationship between the weighted residual error of the maximum suspicious measurement in the initial suspicious measurement set and a preset threshold value; and when the weighted residual error of the maximum suspicious measurement is smaller than a preset threshold value, correcting the state quantity based on a prediction residual error method. According to the bad data correction method and device, the storage medium and the electronic equipment provided by the invention, the initial suspicious measurement set is firstly formed by judging the measurement, then the weighted residual corresponding to the maximum suspicious measurement in the initial suspicious measurement set is calculated, and the relationship between the weighted residual and the preset threshold is judged; and correcting the bad data in the initial suspicious measurement set based on the judgment result. Therefore, the accuracy of bad data identification is guaranteed.
