    摘要: A method is provided for predicting respective trajectories of a plurality of road users. Trajectory characteristics of the road users are determined with respect to a host vehicle via a perception system, wherein the trajectory characteristics are provided as a joint vector describing respective dynamics of each of the road users for a predefined number of time steps. The joint vector of the trajectory characteristics is encoded via an algorithm which included an attention algorithm for modelling interactions of the road users. The encoded trajectory characteristics and encoded static environment data obtained for the host vehicle are fused in order to provide fused encoded features. The fused encoded features are decoded in order to predict the respective trajectory of each of the road users for a predetermined number of future time steps.

    摘要: A method of road detection based on Internet of Vehicles is provided, the method is applied to vehicle terminals and includes: obtaining a target road image captured by an image collection terminal and inputting it into an improved YOLOv3 network, performing feature extraction by using backbone network of dense connection to obtain feature images with different scales; performing feature fusion of top-to-down and dense connection to the feature images by using an improved feature pyramid networks (FPN) to obtain prediction results; obtaining attribute information of the target road image according to the prediction results; the attribute information includes positions and categories of objects in the target road image; the improved YOLOv3 is formed by based on YOLOv3 network, replacing residual modules of backbone network to dense connection modules, increasing feature extraction scale, optimizing feature fusion mode of FPN, performing pruning and performing network recovery processing guided by knowledge distillation.
