摘要:

驾驶员动作识别旨在准确识别驾驶员的行为,对于提升人车交互和保障驾驶安全至关重要。与通用动作识别不同,驾驶员所处环境通常具有挑战性,往往昏暗无光;且随着传感器技术的发展,红外(IR)相机、深度相机等各类相机已被用于分析驾驶员行为。因此,本文提出一种新型多模态融合Transformer,名为MultiFuser,它能识别多模态车内视频之间的跨模态关联与交互,并自适应整合不同模态以获得更优表征。具体而言,MultiFuser由多层双分解模块(Bi-decomposed Modules)构成以建模时空特征,还配备一个模态合成器用于多模态特征整合。每个双分解模块包含一个用于提取模态特定特征的模态专长ViT块(Modal Expertise ViT block),以及一个用于高效跨模态融合的逐块自适应融合块(Patch-wise Adaptive Fusion block)。我们在Drive&Act数据集上开展了大量实验,结果证明了所提方法的有效性。

英文摘要:

Driver action recognition, aiming to accurately identify drivers' behaviours, is crucial for enhancing driver-vehicle interactions and ensuring driving safety. Unlike general action recognition, drivers' environments are often challenging, being gloomy and dark, and with the development of sensors, various cameras such as IR and depth cameras have emerged for analyzing drivers' behaviors. Therefore, in this paper, we propose a novel multimodal fusion transformer, named MultiFuser, which identifies cross-modal interrelations and interactions among multimodal car cabin videos and adaptively integrates different modalities for improved representations. Specifically, MultiFuser comprises layers of Bi-decomposed Modules to model spatiotemporal features, with a modality synthesizer for multimodal features integration. Each Bi-decomposed Module includes a Modal Expertise ViT block for extracting modality-specific features and a Patch-wise Adaptive Fusion block for efficient cross-modal fusion. Extensive experiments are conducted on Drive&Act dataset and the results demonstrate the efficacy of our proposed approach.
