AI Technical Summary

Technical Problem

Existing autonomous driving perception systems lack target recognition accuracy under extreme conditions such as complex road environments, sudden changes in lighting, and rain and snow. They also suffer from unstable cross-scale representation, scarce real data, limited coverage of extreme scenarios, difficulty in aligning virtual and real domain features, and challenges in deploying existing methods on vehicle-mounted devices.

Method used

An obstacle recognition method based on particle-sphere computation is adopted. Obstacle features are trained through a graph neural network model, and a graph structure is constructed by particle-sphere partitioning and hierarchical aggregation to achieve adaptive granularity representation of obstacles and efficient information propagation. The virtual and real features are aligned in conjunction with the metaverse simulation platform.

Benefits of technology

It improves robustness and fine-grained perception accuracy in complex environments, reduces computational costs, and achieves efficient obstacle recognition and virtual-real fusion, making it suitable for both real and virtual driving scenarios.
