Detection and recognition method of "playing mobile phone" behavior based on human body pose estimation

Abstract

The invention proposes a "playing mobile phone" behavior detection and recognition method based on human body posture estimation, which belongs to the field of computer vision and image processing. The key points of the technical solution are: first, the monitoring system is initialized; second, the monitoring system performs data collection; then, the monitoring system performs 2D key point monitoring and skeleton positioning of the human body; then, the monitoring system detects the mobile phone near the "joint point hand"; and then, The monitoring system constructs the space pose relationship of the specific joints of the human body; finally, the monitoring system presets two states of "playing with the mobile phone" and "not playing with the mobile phone" according to the posture of the human body and whether the mobile phone is detected and the spatial position and posture relationship between the mobile phone and the person , if the monitoring system judges that the person detected in the current monitoring scene is in the state of "playing with a mobile phone", an alarm will be issued. The invention can accurately issue an alarm when the detected person has the behavior of "playing with a mobile phone", and meanwhile, the monitoring method has the characteristics of non-contact, non-immersion, wide monitoring range and easy implementation.

Description

technical field [0001] The invention relates to the fields of computer vision and image processing, in particular to the field of a "playing mobile phone" behavior detection and recognition method based on human body posture estimation. Background technique [0002] With the rapid development of information technology, the use of mobile phones is becoming more and more common, and people's dependence on mobile phones is becoming more and more serious. In actual scenarios, accidents caused by playing with mobile phones are not uncommon. For example, the driver takes his hands off the steering wheel because he is playing with his mobile phone while driving, resulting in a car accident. A pedestrian collided with a vehicle while using a mobile phone while crossing the road. Some special industries, such as railway departments, need to adopt militarized management methods for employees, and provide real-time warnings for some violations of employees, including detecting whethe...
