Obstacle trajectory prediction method and device

Abstract

The invention discloses an obstacle trajectory prediction method and device, and the method comprises the steps: outputting a prediction trajectory of a target obstacle under each intention type through a trajectory prediction model according to the collected environment information, the historical trajectory of the target obstacle and all predetermined reference trajectories; the method can improve the depicting precision of the movement tendency of the obstacle under complex conditions, and guides the unmanned vehicle to better avoid the obstacle.

Description

technical field [0001] This description relates to the field of computer technology, in particular to a method and device for trajectory prediction of obstacles. Background technique [0002] Trajectory prediction is an important part of unmanned driving technology. According to the prediction of the future trajectory of the obstacles around the unmanned equipment, it can provide the unmanned equipment with a reasonable understanding of the environment, so as to guide the unmanned equipment. decision-making, planning and control. [0003] The existing trajectory prediction methods usually predict the trajectory of the obstacle in the future based on the historical trajectory of the obstacle to be predicted as the predicted trajectory. [0004] However, the existing trajectory prediction method can only generate a predicted trajectory for obstacles, and because obstacles have various driving tendencies in reality, a predicted trajectory obviously cannot describe the obstacle...

Problems solved by technology

[0004] However, the existing trajectory prediction method can only generate a predicted trajectory for obstacles, and because obstacles have various driving tendencies in reality, a predicted trajectory obviously cannot describe the obstacles in the face of different paths. Various movement tendencies that may exist in complex environments
