Embodiment Construction

[0056] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be noted that the following examples are intended to facilitate the understanding of the present invention, but not to limit it in any way.

[0057] like figure 1 As shown, the violent behavior detection system based on human body posture estimation includes a monitoring terminal, a recognition terminal and an alarm terminal. The monitoring terminal includes four parts, namely the front-end camera, the transmission part, the monitoring center and the cloud; The terminal sends out an alarm after recognition.

[0058] The workflow of the violent behavior detection system is as follows: figure 2 As shown, the details are as follows: the front-end camera is responsible for collecting video information, and then synchronously uploads it to the monitoring center for real-time display and uploading to the cloud for real-time processing; Process...

Abstract

The invention discloses a violent behavior detection system based on human body posture estimation, and the system comprises a video obtaining unit which obtains a monitoring video and synchronously transmits the monitoring video to a monitoring center and a cloud end; T. The monitoring center is used for displaying and storing the monitoring video in real time and supporting playback; T. The cloud is used for converting the monitoring video into multiple frames of images, estimating the human body posture in each frame of image by adopting OpenPose, judging whether a violent behavior exists in the frame of image or not according to four limb directions of the human body posture, judging the type of the violent behavior, and transmitting an analysis result to the alarm unit; and the alarmunit is used for sending alarm information in real time if the cloud identifies that a violent behavior exists in a certain frame of image. The invention further discloses a violent behavior detectionmethod based on human body posture estimation. According to the method, a bottom-up human body posture estimation method is adopted, the robustness is higher, the time cost is stable, and the real-time requirement of the method can be met.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a system and method for detecting violent behavior based on human body pose estimation. Background technique [0002] In recent years, with the increasing popularity of surveillance cameras, a large amount of surveillance data has been generated. If the surveillance data can be analyzed to identify violent behaviors, that is, a series of behaviors that occur in specific public places and endanger public safety, such as fighting etc., it is of great significance to the stability and security of the society. [0003] Human pose estimation is an important branch in the field of computer vision, which is used to locate the key points of the human body in the image, such as the head, shoulders, elbows, etc. There are two approaches at present, including top-down and bottom-up. Among them, the top-down method is to detect the individual first, and then perform single-person p...
