Abstract
This application discloses a positioning data processing method performed at a computing device. The method includes: obtaining a first positioning data sequence generated by a moving target chronologically; performing filtering processing on the first positioning data sequence according to a preset filtering algorithm to obtain a filtered data sequence, and performing adsorption calculation on the filtered data sequence to obtain an adsorption data sequence, the preset filtering algorithm being an algorithm obtained after a Kalman filtering algorithm is corrected according to the adsorption data sequence; outputting the filtered data sequence to obtain a second positioning data sequence of the moving target; and displaying a position corresponding to second positioning data in the second positioning data sequence. The adsorption data sequence is used to correct the Kalman filtering algorithm such that a positioning offset of the moving target is eliminated, thereby improving accuracy of positioning and navigation.
