Track data processing method and device, computer equipment and storage medium

Abstract

The invention relates to a track data processing method and device, computer equipment and a storage medium. The method comprises the steps that track starting data and track ending data correspondingto a target object are acquired, wherein the track starting data and the track ending data are obtained according to positioning, or the track starting data and the track ending data are closed-looptrack data; a corresponding initial correction track data sequence is acquired according to the track starting data and the track ending data, wherein the initial correction track data sequence comprises multiple pieces of initial correction track data, and the initial correction track data is obtained by performing filtering according to measured motion data and predicted motion data corresponding to the target object; and each piece of initial correction track data in the initial correction track data sequence is adjusted according to the track starting data and the track ending data to obtain a target correction track data sequence, wherein the target correction track data sequence is used for determining a target track corresponding to the target object. Through the method, the accuracy of the track data of the target object can be improved.

Description

technical field [0001] The invention relates to the field of positioning, in particular to a trajectory data processing method, device, computer equipment and storage medium. Background technique [0002] With the development of information technology, people pay more and more attention to pattern recognition and fault monitoring of moving objects such as automobiles or aircrafts. The trajectory of the target object is a prerequisite for map generation, pattern recognition, and fault detection. [0003] At present, the trajectory of the moving target is usually determined by GPS technology. However, due to obstacles such as tunnels and weak GPS signals, the trajectory data of the moving target cannot be accurately obtained. Therefore, it is necessary to use the measuring equipment of the moving target to obtain the trajectory in the tunnel. However, there are usually errors in the measurement system, and the resulting trajectory has low accuracy. Contents of the invention...
