Relative Position-Attitude Testing System Based on Twin-Camera

摘要

In this paper, an optical system based-on twin-camera for testing the relative position and pose between spacecrafts is proposed. The primary idea of the system is image sequence analysis based-on feature matching for relative state detection. Computer vision and imaging theory are mainly utilized in this system. The advantages, such as smaller volume, lighter weight, higher precision and lower power consumption, etc, make the system can be widely used in measuring the relative position and attitude between formation-flying spacecrafts.
