Abstract

The embodiment of the invention provides a position estimation and prediction method of a moving object. The method comprises the steps that model parameters of a position prediction model are updated according to a position data sequence of a moving object at the current sampling moment, and the position data sequence comprises position observation data of a plurality of continuous sampling moments before the current sampling moment; determining position prediction data at the current sampling moment according to the position data sequence and the position prediction model after the model parameters are updated; determining position estimation data at the current sampling moment according to the position prediction data and the position observation data at the current sampling moment; and determining position prediction data at the next sampling moment according to position estimation data at the current sampling moment, the position data sequence and the position prediction model after the model parameters are updated, and entering iteration operation at the next sampling moment until the position prediction data of the moving object meets iteration ending conditions.

Description

technical field [0001] The embodiments of the present application relate to the field of position data processing, and in particular, to a method, device, electronic device, and storage medium for estimating and predicting the position of a moving object. Background technique [0002] With the increasing construction of cross-sea bridges and the vigorous development of marine transportation, the safety of cross-sea bridges is facing the serious threat of ship-bridge collision accidents. Predicting the track of ships navigating in the bridge area to judge the risk of ships hitting bridges is an important means to reduce the probability of ship hitting bridge accidents. [0003] In recent years, the automatic identification system (Automatic Identification System, AIS) has been popularized in terms of observing the ship's position; in terms of predicting the ship's track, the widely used prediction method is the speed-based prediction method , In addition to the rate-based fo...
