Problems solved by technology

However, this method has the following disadvantages: when the indoor environment changes, such as lighting, it is necessary to take a new one as the background; the straight line where the shoulders are determined is easily disturbed; judging the sitting posture based on three angles can only correct the human body from one aspect Sitting posture, unable to conduct comprehensive analysis and judgment on sitting posture
However, the information detected during the detection process is only the relative position of the human body and the monitor, and it is impossible to determine whether the human spine is curved

Abstract

The invention relates to an intelligent posture straightening chair, a posture straightening method and a system. The intelligent posture straightening chair comprises a sensor, a video camera, a stepmotor, a buzzer, a loudspeaker, a displayer and a single-chip microcomputer, wherein the sensor is used for acquiring human body sitting posture data; the video camera is used for acquiring human body sitting posture images; the sensor and the video camera are connected with the single-chip microcomputer; the step motor is connected with the single-chip microcomputer; the single-chip microcomputer is used for analyzing the human body sitting posture data and the human body sitting posture images; the height of the chair and the inclination of the chair back are changed through controlling thestep motor; the single-chip microcomputer is separately connected with the buzzer, the loudspeaker and the displayer; the loudspeaker is used for prompting the variation of the oblique degree of theneck; the displayer is used for displaying the variation of the oblique degree of the neck; and the buzzer is used for giving out an alarm when the human body sitting posture data and the human body sitting posture images exceed a set threshold setting value. Through the adoption of the intelligent posture straightening chair, the posture straightening method and the system disclosed by the invention, the accuracy of the sitting posture detecting information can be improved.

Description

technical field [0001] The invention relates to the field of intelligent posture correction of chairs, in particular to an intelligent posture correction seat, posture correction method and system. Background technique [0002] At present, there are mainly three methods for detecting human sitting posture in related experiments: [0003] Through the method of analyzing the angular relationship between the head and shoulders and the horizontal direction. First perform background subtraction to obtain the outline of the human body, and then perform horizontal projection to find the lowest point of the projection to separate the head from the torso. Then, according to the dividing line between the head and the torso, find the edge pixel point where the shoulder is located, and get the straight line where the shoulder is located. Finally, the vertical axis of the head, the angle between the left and right shoulders and the horizontal direction can be obtained. By judging whethe...
