随着自动驾驶技术的快速发展,准确预测行人行为对保障复杂且不可预测交通环境下的安全至关重要。当前对该问题的兴趣凸显了对涵盖非结构化环境的全面数据集的需求,以推动更鲁棒预测模型的发展,提升行人安全与车辆导航能力。本文提出一个针对印度驾驶场景的行人数据集(IDD-PeD),旨在应对非结构化环境中行人行为建模的挑战,包括光照变化、行人遮挡、无信号场景及车-人交互等问题。该数据集提供高阶与低阶相结合的详尽标注,重点关注需引起自车注意的行人。在该数据集上评估现有先进意图预测方法,性能最高下降15%;轨迹预测方法误差最高增加1208 MSE,远超标准行人数据集表现。此外,本文还进行了全面的定量与定性分析,涵盖意图与轨迹基线模型。我们相信,该数据集将为行人行为研究社区带来新挑战,推动更鲁棒模型的构建。
原文摘要 · Abstract (English)
With the rapid advancements in autonomous driving, accurately predicting pedestrian behavior has become essential for ensuring safety in complex and unpredictable traffic conditions. The growing interest in this challenge highlights the need for comprehensive datasets that capture unstructured environments, enabling the development of more robust prediction models to enhance pedestrian safety and vehicle navigation. In this paper, we introduce an Indian driving pedestrian dataset designed to address the complexities of modeling pedestrian behavior in unstructured environments, such as illumination changes, occlusion of pedestrians, unsignalized scene types and vehicle-pedestrian interactions. The dataset provides high-level and detailed low-level comprehensive annotations focused on pedestrians requiring the ego-vehicle's attention. Evaluation of the state-of-the-art intention prediction methods on our dataset shows a significant performance drop of up to $\mathbf{15\%}$, while trajectory prediction methods underperform with an increase of up to $\mathbf{1208}$ MSE, defeating standard pedestrian datasets. Additionally, we present exhaustive quantitative and qualitative analysis of intention and trajectory baselines. We believe that our dataset will open new challenges for the pedestrian behavior research community to build robust models.
