A measurement of human body rotation during parabolic flight experiment

摘要

Purpose - This paper aims to propose a method for measuring the rotation of moving body during parabolic flight using camera. Design/methodology/approach - An orthogonal matrix used to calculate the Euler angles of rotation is solved by means of singular value decomposition. The translation velocity and position of moving body are measured by a binocular camera system. Findings - The experiment is executed in a jet aircraft to simulate micro-gravity during parabolic flight. And the human moving body is regarded as a rigid body. The results show that this method can calculate the angles effectively. Practical implications - This work is useful for calculation and monitoring body's motion in space. Originality/value - The paper gives a method which measures the rotation of a rigid body under the microgravity by a binocular camera to modify the measurement error of the interferometer.
