Collision-Free LSTM for Human Trajectory Prediction.
Lecture Notes in Computer Science(2018)
摘要
Pedestrians have an intuitive ability for navigation to avoid obstacles and nearby pedestrians. If we want to predict future positions of a pedestrian, we should know how the pedestrian adjust his direction to avoid collisions. In this work, we present a simple and effective framework for human trajectory prediction to generate the future sequence based on pedestrian past positions. The method, called Collision-Free LSTM, extends the classical LSTM by adding Repulsion pooling layer to share hidden-states of neighboring pedestrians. The model can learn both the temporal information of trajectories and the interactions between pedestrians, which is in contrast to traditional methods using hand-crafted features such as Social forces. The experiments results on two public datasets show that our model can achieve state-of-the-art performance with assessment metrics.
