This paper aims to propose a method for measuring the rotation of moving body during parabolic flight using camera.
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.
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.
This work is useful for calculation and monitoring body’s motion in space.
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.
The parabolic flight experiment was conducted as a part of the “Ground-based Research Announcement for Space Utilization,” promoted by the Japan Space Forum (JSF) with the cooperation of Diamond Air Service, Inc. This work was supported by the Innovation Fund Project for Graduate Student of Shanghai (JWCXSL0902) and partly supported by the Shanghai Leading Academic Discipline Project (No.S30502) and the Program (No. 08DZ2272800) from Shanghai Committee of Science & Technology.
