Abstract

The invention provides an online multi-pedestrian tracking method based on deep learning, which mainly involves tracking multi-pedestrians in complex scenes by means of deep learning. The method includes: proposing a multi-layer feature fusion network to extract the appearance features of the target. Use a high-precision object detector to detect the position of the object in the video, and extract the appearance features of the object. For different state trajectories, considering the confidence of appearance features and motion features, the difference metric matrix is ​​calculated in different ways. According to the confidence of different state trajectories, combined with the metric matrix, the Hungarian algorithm is used to realize the hierarchical data association of detection and trajectories. Finally, the trajectory information is updated according to the association result. The invention fully considers the confidence of the target motion feature and the appearance feature, and reasonably utilizes the two features to calculate the difference metric matrix. At the same time, the data association method of hierarchical association can better deal with the problems of pedestrian false detection and occlusion, and effectively reduce the number of trajectory ID transformations.
