a method in sitting posture for estimating head posture from relative position changes of key points of face in space
and shoulder posture estimation method of relative position changes of shoulder key points in space is designed.The head posture is divided into 6 types
and the shoulder posture is divided into 2 types.SDM algorithm is used to mark the key points of the face.After marking the key points of face by SDM algorithm
POSIT algorithm is used to estimate the head pose angle to calculate the Euler angle of head and set a threshold to classify head posture.The OpenPose algorithm is used to calibrate the key points of the shoulders.The angle between the left and right shoulder key points is used to estimate the shoulder posture.Through experiments
the method has good head and shoulder posture detection and high posture estimation accuracy.
