Abstract

The invention discloses a vehicle track prediction method and device, equipment and a storage medium, and relates to the technical field of computers, in particular to the technical field of vehicle safety. According to the specific implementation scheme, multiple first historical position points of a current vehicle in a first historical driving time period are obtained, and the multiple first historical position points are fitted to obtain a first fitting result; and collecting a current position point of the current vehicle, and predicting a driving track of the current vehicle according to the current position point and the first fitting result. The first fitting result is obtained by obtaining the first historical position point, the driving track of the current vehicle is predicted according to the current position point and the first fitting result, dependence on vehicle signals is not needed, the prediction cost is reduced, and the track prediction efficiency and precision are improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of vehicle safety technology, and in particular to a method, device, equipment and storage medium for predicting vehicle trajectory. Background technique [0002] With the rapid development of the transportation industry, the number of road vehicles has increased sharply, and the traffic safety situation has become increasingly severe. It is difficult for drivers to estimate the probability of vehicle collisions based on vehicle trajectories while driving, which poses a great threat to the personal safety of drivers and passengers. [0003] At present, when predicting the driving trajectory of a vehicle, it is mainly based on parameters such as the steering wheel, wheelbase, and wheelbase of the vehicle, or using radar to detect the distance and speed of the preceding vehicle to estimate the collision time. [0004] However, the cost of radar is relatively h...
