Abstract:

To address the problems that the pedestrian interaction feature of the Social GAN is simple and that it cannot make full use of the most of pedestrian interaction information, this paper proposes a pedestrian trajectory prediction model with social features and attention mechanism. This model adapts the structure of generative adversarial networks. The generator adapts an encoder-decoder model and the attention model is put between encoder and decoder. Three social features are set to enrich pedestrian interaction information which assists the attention module to make full use of the most of pedestrian interaction information by allocating the influence of pedestrians in the scene, so that the accuracy of the model is improved. Experimental results on multiple datasets show that the accuracy of this model in the pedestrian trajectory prediction task is increased by 15% compared with the previous pedestrian trajectory prediction model based on the pooling module. The improvement effect is most obvious in scenes with dense pedestrians and lots of non-straight tracks, with the accuracy increased by 34%.

Key words: trajectory generation, generative adversarial networks, attention mechanism, long short-term memory, pedestrian interaction
