Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings. according to Figure 7 The flow shown is an introduction to the method of pedestrian trajectory prediction in complex scenes.

[0048] Such as figure 1 As shown, firstly, the original background picture frame corresponding to the data set is put into the 16-layer convolutional neural network of the visual geometry group as input for learning and encoding, and the hidden terrain feature vector is obtained. Input the physical terrain feature vector into the physical attention module, perform the mean value operation on it, and then use the hyperbolic tangent activation function for data processing. After using the fully connected layer for dimension docking, connect it with the original physical terrain feature vector, and then After the dimension conversion is performed through a fully connected network, the normalized index operation is performed, and the point multipl...

Abstract

The invention discloses a multi-modal trajectory prediction method for pedestrians in a complex scene. The method comprises the following steps: performing picture feature extraction by using a 16-layer convolutional neural network of a visual geometry group; performing feature processing on the trajectory data by using a full connection layer; inputting a trajectory data feature vector VS to enter a generative adversarial network to complete a coding and decoding network function; inputting picture feature data and track feature data to physics, wherein a social attention module considers terrain limitation and pedestrian interaction; obtaining a better track generation prediction result through the updated generator part; and obtaining a stable trajectory prediction model SPM. Accordingto the method, the prediction precision can be effectively improved, a plurality of reasonable prediction tracks can be generated, the related terrain limitation information can be extracted accordingto the feature information of the original picture, and the social interaction situation between different pedestrians in the same complex scene can be considered. The method can predict the future track of the pedestrian more quickly and accurately.

Description

technical field [0001] The invention relates to a multimodal trajectory prediction technology, in particular to a multimodal trajectory prediction method for pedestrians in complex scenes. Background technique [0002] In modern Chinese society, as the population continues to increase, the resulting complex situations are becoming more and more common, such as park assemblies, railway station squares, large concert entrances, marathon sports, etc. In these complex scenes, we often have to consider different possible social and even public security issues such as pedestrian gathering, dispersal, risk avoidance, and queuing. In such a vast and complex scene, if only manual recognition is used to regulate and manage the current scene, The efficiency is too low, which greatly affects the speed of crowd diversion and the efficiency of safety avoidance. Therefore, the prediction of the future trend of pedestrian trajectories in complex scenes must be closely related to the latest...
