Abstract

The invention discloses a vehicle driving track correction method and device and computer equipment. The method comprises the steps of obtaining original driving data of a vehicle; taking the position determined by the positioning information of the track point at the moment 1 as the optimal estimation position of the track point at the moment 1; selecting a track point at the moment k (k is greater than or equal to 2), and calculating a predicted value of the motion displacement of the track point at the moment k; calculating a covariance matrix; calculating an observed value of the motion displacement of the track point at the moment k; calculating the Kalman filtering gain at the moment k and the optimal estimated value of the motion displacement of the track point at the moment k; calculating the optimal estimation position of the track point at the moment k; taking the optimal estimation position of the track point at the moment k as the correction position of the track point at the moment k, and updating the covariance matrix; and traversing all the track points. The new driving track obtained after the driving track is corrected can reflect the actual driving process of a customer more truly, and the actual driving track of the vehicle can be restored more accurately.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a method, device and computer equipment for correcting the driving trajectory of a vehicle. Background technique [0002] The continuous progress of big data and artificial intelligence technology has accelerated the arrival of the era of big data in the Internet of Vehicles. In recent years, the Internet of Things has flourished, and the Internet of Vehicles technology has been continuously integrated into real life. More and more vehicles are equipped with Internet of Vehicles devices. The Internet of Vehicles device can determine the geographic location of the current driving process of the vehicle through GPS satellite or Beidou satellite positioning, and then collect the positioning data and send it to the server. Further, according to the obtained positioning data, the server can count the travel trajectory of the vehicle and the travel data such as ...
