Motion track reconstruction method and device, storage medium and electronic device

Abstract

The invention discloses a motion track reconstruction method and device, a storage medium and an electronic device. The method includes the following steps: obtaining a data set, wherein positioning data obtained by positioning a target object during movement of the target object is stored in the data set; fitting a part of the positioning data in the data set to obtain multiple sections of firstcurves, wherein the first curve are obtained by fitting a plurality of positioning data with adjacent acquisition time and a proportion of noise data in the other part of the positioning data of the data set is higher than a proportion of noise data in the part of the positioning data of the data set; and determining a motion track of the target object based on the multiple sections of the first curves. The motion track reconstruction method and device, the storage medium and the electronic device solve the technical problem of low accuracy rate of reconstruction of the motion rack of a vehicle in the related art.

Description

Technical field [0001] The present invention relates to the field of electronic maps, in particular to a method and device for reconstructing a motion track, a storage medium and an electronic device. Background technique [0002] With the increase in vehicles and the increase in travel demand, people are increasingly dependent on car navigation. The accuracy of navigation and positioning has become the most important factor for people to choose car navigation devices. [0003] The vehicle positioning system in the related art generally relies on GPS signals or network signals, and the positioning module of the vehicle positioning system can obtain positioning results only through GPS signal or network signal transmission or network transmission. However, when a vehicle travels to a location where there is no GPS signal or network signal, such as a tunnel or underground garage, the vehicle cannot achieve accurate positioning through the positioning data collected by GPS, and can o...

Problems solved by technology

On the one hand, when a driving vehicle enters an area where the vehicle positioning signal is weak or has no vehicle positioning signal, the driving vehicle is in a "temporarily lost" state, and the driving vehicle cannot be accurately positioned due to the inability to obtain accurate vehicle positioning signals; On the one hand, due to the poor positioning accuracy of the positioning chip used by the civilian vehicle navigation terminal, the vehicle monitoring center inevitably receives drifting positioning data (that is, the vehicle position data indicating that the current position of the vehicle is offset from the actual position of the vehicle), Eventually, the vehicle driving curve on the monitoring interface of the vehicle trajectory monitoring system deviates from the actual vehicle trajectory, which misleads the vehicle driver and reduces the user's navigation experience

[0005] For the above problems, no effective solution has been proposed
