SmartCooper: Vehicular Collaborative Perception with Adaptive Fusion and Judger Mechanism
CoRR(2024)
摘要
In recent years, autonomous driving has garnered significant attention due to
its potential for improving road safety through collaborative perception among
connected and autonomous vehicles (CAVs). However, time-varying channel
variations in vehicular transmission environments demand dynamic allocation of
communication resources. Moreover, in the context of collaborative perception,
it is important to recognize that not all CAVs contribute valuable data, and
some CAV data even have detrimental effects on collaborative perception. In
this paper, we introduce SmartCooper, an adaptive collaborative perception
framework that incorporates communication optimization and a judger mechanism
to facilitate CAV data fusion. Our approach begins with optimizing the
connectivity of vehicles while considering communication constraints. We then
train a learnable encoder to dynamically adjust the compression ratio based on
the channel state information (CSI). Subsequently, we devise a judger mechanism
to filter the detrimental image data reconstructed by adaptive decoders. We
evaluate the effectiveness of our proposed algorithm on the OpenCOOD platform.
Our results demonstrate a substantial reduction in communication costs by
23.10% compared to the non-judger scheme. Additionally, we achieve a
significant improvement on the average precision of Intersection over Union
(AP@IoU) by 7.15% compared with state-of-the-art schemes.
