摘要:

近年来,多模态大语言模型(MLLMs)在一般视觉理解方面展现了出色的性能。然而,其在安全关键驾驶场景中的应用受限于无法准确感知和推理罕见高风险动态事件(如碰撞或接近碰撞)的能力。为此,我们提出了一种增强MLLM感知能力的流程,通过融合降采样视频帧与同步高频telematics数据(IMU和GPS)以及专用计算机视觉模型的语义信息生成高质量的伪标签,包括描述性标题和问答对,专门用于训练MLLM识别和描述现实驾驶中的安全关键事件(SCEs)。我们通过微调开源QwenVL-2.5模型并使用DoRA适配器展示了该方法的有效性:实验表明在少于50M可训练参数和有限计算预算下,显著提高了识别和解释安全关键事件的能力。

英文摘要:

Recent advancements in Multimodal Large Language Models (MLLMs) have demonstrated impressive capabilities in general visual understanding. However, their application to safety-critical driving scenarios remains limited by an inability to accurately perceive and reason about rare high-stakes dynamic events, such as collisions or near-collisions. To address this, we introduce a pipeline that enhances MLLM perception by fusing downsampled video frames with synchronized high-frequency telematics data (IMU and GPS) and semantic insights from specialized computer vision models. Our pipeline generates high-quality pseudo-labels, including descriptive captions and question-answer pairs, specifically designed to train MLLMs to identify and describe Safety-Critical Events (SCEs) in real-world driving footage. We show the effectiveness of our approach fine-tuning the open-source QwenVL-2.5 model via DoRA adapters: our experiments demonstrate significant improvements in identifying and explaining safety-critical events, with fewer than 50M trainable parameters and limited computational budget.
