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

Abstract

This specification discloses a trajectory prediction method and device for an obstacle. According to the collected environmental information, the historical trajectory of the target obstacle, and each predetermined reference trajectory, through the trajectory prediction model, the target obstacle can be output The predicted trajectory under each intention type and the predicted probability of the target obstacle moving on each predicted trajectory can improve the accuracy of describing the movement tendency of obstacles in complex situations, thereby guiding the unmanned vehicle to better avoid obstacles.

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...
