论文摘要
在自主驾驶系统的背景下,预测道路使用者的行为,尤其是行人的行为对于安全运动计划至关重要。传统上,根据预测未来的轨迹,行人行为预测已实现。但是,最近的证据表明,预测高级行动,例如越过道路,可以帮助改善轨迹预测和计划任务。有许多现有数据集可满足行人行动预测算法的发展,但是,它们缺乏某些特征,例如伯德的眼睛视图语义图信息,现场对象的3D位置等,在自主驾驶环境中至关重要。为此,我们提出了一个新的行人行动预测数据集,该数据集通过将人均2D/3D边界框和行为注释添加到流行的自主驾驶数据集Nuscenes创建。此外,我们提出了一种混合神经网络体系结构,该结构结合了各种数据模式,以预测行人穿越行动。通过在新提出的数据集上评估我们的模型,可以揭示不同数据方式对预测任务的贡献。该数据集可从https://github.com/huawei-noah/pepscenes获得。
Predicting the behavior of road users, particularly pedestrians, is vital for safe motion planning in the context of autonomous driving systems. Traditionally, pedestrian behavior prediction has been realized in terms of forecasting future trajectories. However, recent evidence suggests that predicting higher-level actions, such as crossing the road, can help improve trajectory forecasting and planning tasks accordingly. There are a number of existing datasets that cater to the development of pedestrian action prediction algorithms, however, they lack certain characteristics, such as bird's eye view semantic map information, 3D locations of objects in the scene, etc., which are crucial in the autonomous driving context. To this end, we propose a new pedestrian action prediction dataset created by adding per-frame 2D/3D bounding box and behavioral annotations to the popular autonomous driving dataset, nuScenes. In addition, we propose a hybrid neural network architecture that incorporates various data modalities for predicting pedestrian crossing action. By evaluating our model on the newly proposed dataset, the contribution of different data modalities to the prediction task is revealed. The dataset is available at https://github.com/huawei-noah/PePScenes.
