Vehicle trajectory prediction model establishment and prediction method

Abstract

The invention relates to a vehicle trajectory prediction model establishment and prediction method. The vehicle trajectory prediction model establishment method comprises the following steps: acquiring historical driving trajectory data of a vehicle, and constructing single vehicle trajectory data and road network vehicle trajectory data of the vehicle; carrying out screening to obtain screened single vehicle trajectory data and screened road network vehicle trajectory data; carrying out bayonet completion to obtain effective single vehicle trajectory data and effective road network vehicle trajectory data; establishing a prediction model of the effective single vehicle trajectory data; establishing a prediction model of the effective road network vehicle trajectory data; according to theprediction model of the effective single vehicle trajectory data and the prediction model of the effective road network vehicle trajectory data, constructing a fusion training set; and according to the fusion training set, training a set prediction model and generating a vehicle trajectory prediction model. According to the method in the invention, the data is effectively processed, the calculation amount is reduced, and the prediction is enabled to be more accurate and closer to the actual condition.

Description

technical field [0001] The invention relates to the technical field of vehicle trajectory prediction, in particular to a vehicle trajectory prediction model establishment and prediction method. Background technique [0002] In the traditional vehicle trajectory prediction, most vehicle-mounted GPS devices are used to collect vehicle location data, so as to obtain the vehicle's driving trajectory, and analyze and use the historical driving trajectory data to predict the vehicle trajectory. However, using this method to collect vehicle location data has its limitations. The popularization of vehicle-mounted GPS is extremely slow, and many vehicles are not equipped with GPS. Therefore, at present, there are a lot of vehicle position data obtained through cameras. Since cameras are installed on various roads, it has become very common, and image recognition technology has also been greatly developed. Vehicle position data can be obtained by shooting vehicles through cameras, and...
