Robust Collaborative Perception against Temporal Information Disturbance

Collaborative perception facilitates a more comprehensive representation of the environment by leveraging complementary information shared among various agents and sensors. However, practical applications often encounter information disturbance which includes perception packet loss and time delays, and a comprehensive framework that can simultaneously address such issues is absent. In addition, the feature extraction process prior to fusion is not sufficient, as it lacks exploration of the local semantics and context dependencies of individual features. To enhance both accuracy and robustness, this paper introduces a novel framework named Robust Collaborative Perception against Temporal Information Disturbance, which predicts perception information when disturbance occurs. Specifically, the Historical Frame Prediction (HFP) module is introduced to make compensation for information loss with temporal association excavation of historical features. Based on the predicted features generated by the HFP module, the Pyramid Attention Integration (PAI) module is introduced to augment local semantics and incorporate global long-range dependencies through multi-scale window attention. Compared with existing methods on the publicly available dataset OPV2V, our approach exhibits superior performance and expanded robustness in the 3D object detection task.
