Abstract

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.
