Abstract

The embodiment of the invention provides a trajectory prediction method and device, and relates to the field of local navigation of robots and intelligent vehicles. The trajectory prediction method and device are applied to a vehicle provided with an in-vehicle camera. The method comprises the following steps: photographing a surrounding environment using the in-vehicle camera to acquire a video sequence including a surrounding vehicle and a vehicle background; positioning the surrounding vehicle from the video sequence and extracting the historical trajectory information of the surrounding vehicle, and using scene semantic information obtained by performing image segmentation on the video sequence as auxiliary information; and inputting the historical trajectory information and the auxiliary information into a neural network model to obtain a predicted trajectory of the surrounding vehicle. The trajectory prediction method can improve the accuracy of prediction of vehicle trajectories.

Description

technical field [0001] The invention relates to the field of local navigation of robots and intelligent vehicles, in particular to a trajectory prediction method and device. Background technique [0002] During vehicle driving, it is very important to predict the future trajectories of other traffic participants to avoid the autonomous vehicle from crashing into other vehicles. Assuming that all traffic participants obey the traffic rules and human drivers can subconsciously predict the future trajectory of the target, for autonomous vehicles, the method of building a model is usually used to predict the future trajectory of other traffic participants. [0003] However, most current works either use static images to extract visual-semantic messages, or adopt an end-to-end structure to learn driving networks, the former ignores temporal continuity in driving situations, and the latter lacks the interpretability of training networks, thus causing The problem of low accuracy i...
