摘要:

推断道路使用者之间以及道路使用者与其周围物理空间之间的关系行为是对道路场景中参与者所采用的导航策略进行有效建模和预测的重要一步。为此,我们提出了一个关系感知的框架,未来的轨迹预测。我们的系统的目的是推断关系信息的道路使用者相互之间的互动和与环境。第一个模块涉及时空特征的视觉编码,它捕捉随着时间的推移人与人和人与空间的互动。下面的模块显式地从时空交互中构建成对关系,并通过考虑其过去的轨迹来识别高度影响目标道路用户的未来运动的更多描述性关系。由此产生的关系特征用于预测目标的未来位置,以热图的形式,具有空间依赖性的额外指导和不确定性的考虑。对公共基准数据集的广泛评估表明,所提出的框架的鲁棒性和有效性,表现高于最先进的方法。

英文摘要:

Inferring relational behavior between road users as well as road users and their surrounding physical space is an important step toward effective modeling and prediction of navigation strategies adopted by participants in road scenes. To this end, we propose a relation-aware framework for future trajectory forecast. Our system aims to infer relational information from the interactions of road users with each other and with the environment. The first module involves visual encoding of spatio-temporal features, which captures human-human and human-space interactions over time. The following module explicitly constructs pair-wise relations from spatio-temporal interactions and identifies more descriptive relations that highly influence future motion of the target road user by considering its past trajectory. The resulting relational features are used to forecast future locations of the target, in the form of heatmaps with an additional guidance of spatial dependencies and consideration of the uncertainty. Extensive evaluations on the public benchmark datasets demonstrate the robustness and efficacy of the proposed framework as observed by performances higher than the state-of-the-art methods.
