摘要:

在自主导航中,规划系统推理其他智能体来规划安全且合理的轨迹。在规划开始之前,代理通常使用计算密集型模型进行处理,用于识别,跟踪,运动估计和预测。由于有限的计算资源和大量的代理实时的处理,它成为重要的是有效地排名代理根据他们对决策过程的影响。这允许花费更多的时间处理最重要的代理。我们提出了一个系统,排名代理周围的自动驾驶汽车(AV)在实时的。我们通过在真实世界的日志数据上运行模拟规划器来自动生成排名数据集,这样我们就可以在所有代理上运行更准确和更昂贵的模型。各种计划器动作的原因被记录并用于分配地面实况重要性分数。生成的数据集可用于学习排名模型。特别是,我们展示了通过卷积神经网络将学习到的特征与设计用于捕获领域知识的工程特征相结合的实用性。我们展示了各种设计选择的好处实验。当在真实的自动驾驶汽车上进行测试时,我们的系统展示了理解复杂驾驶情况的能力。

英文摘要:

In autonomous navigation, a planning system reasons about other agents to plan a safe and plausible trajectory. Before planning starts, agents are typically processed with computationally intensive models for recognition, tracking, motion estimation and prediction. With limited computational resources and a large number of agents to process in real time, it becomes important to efficiently rank agents according to their impact on the decision making process. This allows spending more time processing the most important agents. We propose a system to rank agents around an autonomous vehicle (AV) in real time. We automatically generate a ranking data set by running the planner in simulation on real-world logged data, where we can afford to run more accurate and expensive models on all the agents. The causes of various planner actions are logged and used for assigning ground truth importance scores. The generated data set can be used to learn ranking models. In particular, we show the utility of combining learned features, via a convolutional neural network, with engineered features designed to capture domain knowledge. We show the benefits of various design choices experimentally. When tested on real AVs, our system demonstrates the capability of understanding complex driving situations.
