The method includes: obtaining attitude data in a period of time; performing a linear regression analysis on the attitude data and time points in the time period to obtain a regression line (L) and a standard deviation; obtaining a deviation value between the attitude data and the regression line (L) at each of the time points; excluding the attitude data for which the deviation value is greater than or equal to at least twice the standard deviation; grouping the attitude data according to a grouping value to form clusters; comparing a total quantity of the attitude data in each of the clusters, and defining one of the clusters with a largest total quantity as an ideal cluster; and calculating an average of the attitude data in the ideal cluster as a reasonable attitude data.",
