Method and system for detecting abnormal sitting postures

Abstract

The invention provides a method for detecting abnormal sitting postures. The method comprises the following steps: S1, presetting standard sitting posture data; S2, using a sitting posture processing calculation module for obtaining sitting posture information data; S3, comparing the real-time sitting posture information data with the standard sitting posture data; S4, judging whether deviation exceeds threshold value or not, if not, entering the step S2 again; if so, carrying out the next step; S5, judging whether state duration exceeding threshold value in step 2 exceeds specified period- if not, executing the step S2 again, and if yes, executing the next step; and S6, giving an alarm when the sitting posture is abnormal.

Description

technical field [0001] The invention relates to the field of head detection, in particular to a detection method and system for detecting abnormal sitting posture. 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 information security and electronic authentication, 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 t...

AI Technical Summary

Problems solved by technology

Because this method only uses the tilt angle of the face, it can only judge the abnormal sitting posture when the face is tilted, but cannot judge the abnormal sitting posture when the face is sideways

In addition, because this method is easily affected by light, different people have different sitting posture standards, so it is easy to cause errors when detecting different people

[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.
