Human body posture estimation method and device based on filtering algorithm

The embodiment of the invention discloses a human body posture estimation method and device based on a filtering algorithm, and the method comprises the steps: extracting a plurality of human body key points in a target video frame based on a pre-stored human body posture estimation model; setting the width of a filtering window, and obtaining a plurality of data points in the filtering window; fitting the plurality of human body key points and the plurality of data points based on a pre-stored filtering algorithm model to obtain a joint matrix for any human body key point; and obtaining posture positions corresponding to the plurality of human body key points according to the joint matrix. According to the method, on the basis of existing human body posture estimation, the joint matrix is obtained through optimization of the filtering algorithm, the corresponding posture position is obtained through the joint matrix, the action relation between the associated key points is fully considered, and the output po
