Embodiment Construction

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are part of the embodiments of the present invention, but not all of them.

[0048] In order to deal with the algorithmic heterogeneity of the pedestrian behavior analysis model, that is, the pedestrian behavior analysis model of different scenes under different pedestrian behavior dimensions contains different pedestrian behavior feature extraction and description algorithms, and meets the requirements of computing hardware (such as the usual deep learning network needs Use the image processor GPU to carry out parallel accelerated calculation), the monitoring video multi-dimensional pedestrian behavior intelligent analysis system of the present invention uses the micro-service architecture design, each pedestrian behavior analysis model is used as an independent service, ado...

Abstract

The invention relates to a monitoring video multi-dimensional pedestrian behavior intelligent analysis system and method. The system comprises an individual behavior analysis module, a small group behavior analysis module, a group behavior analysis module, a scene analysis module, a pedestrian behavior dimension evaluation module, an intelligent gateway, an application logic integration module anda video source management module. The method comprises the following steps: acquiring a monitoring video data stream, extracting video frames from the monitoring video data stream, and performing scene classification and pedestrian behavior dimension selection by using key video frame data; combining the scene and pedestrian behavior dimension information; performing decisions selected by the pedestrian behavior analysis module and transmission of management data; and performing intelligent behavior recognition through a pedestrian behavior analysis model of a scene integrated in the pedestrian behavior analysis module under the selected behavior dimension, and outputting a final pedestrian behavior recognition result. Pedestrian behavior recognition in various complex monitoring scenes and pedestrian behavior dimensions can be supported.

Description

technical field [0001] The invention relates to the technical fields of computer science, machine vision and artificial intelligence, in particular to a monitoring video multi-dimensional pedestrian behavior intelligent analysis system and method. Background technique [0002] Intelligent video analysis technology has very important applications in the fields of current security monitoring, entertainment, human-computer interaction and automatic driving. Pedestrian behavior analysis and recognition is one of the key technical difficulties. For example, by identifying the behavior or movement trend of pedestrians in the surveillance video to determine whether there is any abnormal behavior, so as to realize functions such as intelligent alarm for public emergencies. Therefore, intelligent video surveillance has an urgent application demand in the field of public security. In addition, automatic driving decision-making can also be assisted by identifying pedestrian behavior ...
