Body Movement Cancellation Based on Hybrid Radar-Webcam Sensing System

In the process of using radar to detect vital signs, the body movement often has a significant impact on the accuracy of data, and how to reduce or even eliminate this impact is a topic of concern at present. In this paper, a method of body movement elimination based on optical flow method is proposed. In the process of the experiment, the experimenter is required to simulate the possible body movement, calculate the optical flow vector through the optical flow method, to obtain the change in the distance between the human body and radar, and finally reduce the impact of body movement on the detection of vital signs. Experimental results show that this method can eliminate effectively.
