Abstract

The invention discloses a subway station pedestrian abnormal event detection method based on deep learning. According to the method, the most advanced detection and tracking algorithm in deep learningis adopted; the method can be used for automatic real-time detection of pedestrian abnormity in a subway station. Pictures describing pedestrians are made into a pedestrian detection data set and sent to a deep residual convolutional neural network for training. A pedestrian detection model is obtained, a pedestrian tracking algorithm Deepsort is used for completing pedestrian tracking with a detection result as input, the tracking result is further processed, and detection and judgment of specific pedestrian abnormal behaviors are completed in combination with a warning line detection result. The method has the advantages that the detection precision is high, the speed reaches 15FPS, and the real-time requirement of monitoring can be met.

Description

【Technical field】 [0001] The invention relates to the technical field of video processing, in particular to a method for detecting abnormal pedestrian events in subway stations based on deep learning. 【Background technique】 [0002] Subway transportation has become an extremely important mode of public transportation today, and plays an extremely important role in the development of the national economy. At present, major cities are actively developing and constructing subway transportation. In daily life, people will also be more choose the subway. Compared with other modes of transportation, subway transportation has the advantages of large transportation volume, fast speed, saving ground space, environmental protection and energy saving, etc., but at the same time, subway operation also has its own particularities. Areas such as escalators are generally one-way traffic, and once passengers have relevant abnormal behaviors, if the staff cannot detect them in time and take...
