A Method of Indoor Dangerous Situation Alarming Based on Human Body Posture Tracking Analysis

Abstract

The present invention is an indoor dangerous situation alarm method based on human body posture tracking analysis, which applies the human body recognition technology based on the artificial intelligence network to household appliances such as air conditioners, improves the single function of the original household appliances, and increases the ability to judge and identify children at home. Dangerous behaviors that may cause injury, such as moving home appliances, climbing high places, and touching sockets, etc., can trigger alarms in time when dangerous behaviors are found, and increase the ability to judge and identify elderly people who accidentally fall at home or send specific help gestures. Trigger the alarm in time; further judge whether there is a dangerous situation in the home, such as fire, etc., if found, the alarm can be triggered in time.

Description

technical field [0001] The invention relates to a method for warning indoor dangerous situations based on human body posture tracking analysis. Background technique [0002] Motion Capture is a measurement technique that records the movement of an object and simulates it into a digital model. Motion capture involves various calculation methods such as measurement, physical positioning, and spatial positioning, as well as the intercommunication and processing between data and computers. By setting the tracker on the key part of the moving object or obtaining the position of the target point by other means, and then get the data of the three-dimensional space coordinates after computer processing, and apply the data in animation production, gait analysis, biomechanics, man-machine Engineering and other fields. [0003] Human body recognition refers specifically to computer technology that uses analysis and comparison of human visual feature information to distinguish people ...

Problems solved by technology

These problems are difficult to solve by traditional rule-based programming

[0007] In the current human motion capture and posture analysis system, the background difference method is usually used for foreground detection, and the Gaussian model is often used for background modeling. This method is computationally intensive, slow, and easily affected by shadows. The detected target image has noise, and Targets that pause motion are absorbed as part of the background, resulting in holes inside the target

Moreover, the extraction of human joint points usually adopts optical marking or manual calibration, which has a large human error and a low degree of automation. Moreover, the current automatic extraction method of human joint points usually adopts the method of curve fitting, which has a large amount of calculation and low accuracy. universal applicability

[0008] In addition, there is no solution for human body posture analysis and tracking on air conditioners, and it is impossible to detect abnormal human movements, such as elderly people falling down, children falling down, or moving heavy appliances and other behaviors that may cause danger. alarm
