Intelligent lamp pole crowd behavior recognition method and device based on human body joint point coordinates

Abstract

The invention relates to an intelligent lamp pole crowd behavior recognition method based on human body joint point coordinates. The method specifically comprises the following steps: S1, constructingan image training set for human body behavior recognition and a human body joint point coordinate data set corresponding to human body behaviors; S2, acquiring crowd behavior information and extracting human skeleton behaviors by a camera of the intelligent lamp post, and interpolating the human skeleton behaviors without articulation points in the crowd behavior information according to the human articulation point coordinate data set; S3, setting a time attention layer for human skeleton behaviors, extracting features of the human skeleton behaviors, then constructing a deep learning network, and setting corresponding hyper-parameters; and S4, training the deep learning network through the deep learning open source framework to obtain a crowd behavior recognition model, and recognizingnewly obtained crowd behavior information through the crowd behavior recognition model. Compared with the prior art, the method has the advantages of improving the human body behavior recognition rate, reducing the influence of shielding objects on the recognition result and the like.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a method and device for identifying crowd behavior on smart light poles based on coordinates of joint points of a human body. Background technique [0002] With the rapid development and application of computer vision and artificial intelligence, video analysis technology has been flourishing and widely used in many fields of human life. Such as smart security, human-computer interaction, smart home and smart medical care. With the continuous improvement of video surveillance systems in Chinese urban communities, smart communities have also become a new mode of social management innovation. As the edge intelligent hardware of cloud-controlled services in the future "AI+5G" smart community, smart light poles will play a key role in boosting the construction and development of smart communities. Based on the monitoring video of smart light poles, computer vision technology is appli...
