Sitting posture detection method and system

Abstract

The invention provides a detection method for sitting posture detection. The detection method comprises the following steps: S1, processing a sitting posture calculation module for the first time; S2, registering a standard sitting posture; S3, judging whether registration succeeds or not; if not, entering the step S2 again; if so, carrying out the next step; S4, processing the sitting posture calculation module again; S5, comparing the real-time coordinates with the standard sitting posture deviation; S6, judging whether deviation exceeds threshold value or not, if not, entering the step S4 again; if so, carrying out the next step; S7, judging whether state duration exceeds specified period- if not, executing the step S4 again, and if yes, executing the next step; S8, giving an alarm when the sitting posture is abnormal, and assigning Alarm = 1; S9, processing the sitting posture calculation module for obtaining sitting posture information; S10, comparing the deviation of the real-time coordinate and the standard coordinate again; S11, judging whether sitting posture reaches standard or not if not, entering the step S8 again; if so, cancelling the alarm, resetting Alarm to be equal to 0, and executing the step S4 again.

Description

technical field [0001] The invention relates to the field of human head detection, in particular to a detection method and system for sitting posture detection. Background technique [0002] With the continuous development of science and technology, especially the development of computer vision technology, head detection technology is widely used in various fields such as video surveillance and security, and the image feature extraction method has good recognition performance. Among them, sitting posture detection is also an important content in the field of recognition. In the prior art, it includes 1. Measuring the distance between the person and the sensor based on ultrasonic waves, laser lines, etc., and judging whether the sitting posture is standard or not. 2. Based on the depth sensor, collect information about people's sitting posture, extract key data to establish a sitting posture model, and use the sitting posture model to detect and judge the actual sitting post...

Problems solved by technology

Because this method uses the face detection module and obtains the inclination angle of the face to judge the sitting posture, when the face is too large or blocked by other objects (such as wearing a mask, etc.), the complete face cannot be guaranteed to appear in the image , the failure of face detection leads to the failure of angle and human eye state detection, which eventually leads to the failure of sitting posture detection

[0006] 3. The patent CN107169453A is based on the depth sensor for sitting posture detection. It needs to use the depth sensor to obtain the depth image. The cost of the depth sensor is higher than that of the ordinary image sensor.
