Abstract

A vehicle trajectory prediction method. The vehicle trajectory prediction method comprises the following steps: obtaining GNSS data of a vehicle (S10); extracting data information of a target key GNSS data point in the GNSS data according to a preset sampling rule (S20); fitting historical trajectories according to a preset fitting formula and the data information (S30); and calculating a predicted traveling trajectory of the vehicle according to the fitted historical trajectories (S40). Also provided is a vehicle trajectory prediction device. The technical solution reduces consumption of locally stored resources.

Description

technical field [0001] The invention relates to the technical field of vehicle detection, in particular to a vehicle track prediction method and device. Background technique [0002] At present, a large number of GNSS data records can be used as a source of fitting vehicle trajectory during the driving process of the vehicle, but from the perspective of artificial intelligence, a large number of vehicle GNSS data can be used as the basis for mining the driving state of the vehicle. At present, there are many trajectory prediction technologies, such as Markov chain method, inertial navigation method, Kalman filter method, particle filter method, least square method, Gaussian mixture model, neural network, machine learning method, topology theory and Other more complex trajectory prediction methods. The above various trajectory prediction methods exist at the level of theoretical research, and there are few practical algorithms for vehicle trajectory prediction. Because ther...
