Abstract

The invention provides an unmanned aerial vehicle track processing method and device, electronic equipment and a storage medium. The method comprises the following steps of based on M groups of time difference information of a plurality of TDOA stations at a Kth moment, determining an actual measurement position of an unmanned aerial vehicle at the Kth moment; each group of time difference information representing the time difference of the signals of the unmanned aerial vehicle received by the two corresponding TDOA stations at the corresponding moment; judging whether the actually measured position at the Kth moment deviates or not; if the position deviation occurs, determining the predicted position of the unmanned aerial vehicle at the Kth moment according to the track position of the Lth moment in the track of the unmanned aerial vehicle; wherein L is smaller than K; and taking the predicted position of the Kth moment as a track position of the Kth moment in the track so as to update the track.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicles, in particular to a method, device, electronic equipment and storage medium for processing a trajectory of an unmanned aerial vehicle. Background technique [0002] In recent years, UAVs have been used in various fields, and the efficient positioning of UAVs and the precise processing of their trajectories have become the development trend of the industry. [0003] TDOA positioning is a positioning method using time difference. For example, the position of the signal can be determined by measuring the absolute time difference of the signal arriving at each monitoring station, and drawing a hyperbola with the detection station as the focus and the distance difference as the long axis. [0004] According to the TDOA positioning principle, its positioning accuracy is affected by the geometric form of the base station layout and the calculation accuracy of the time difference. The infl...
