Binocular Vision-based Relative Position and Attitude Determination Between Spacecrafts

This paper introduces the basic principles of optical measurements and modeled binocular vision measurement system.We also discuss the measurement method of the relative position and relative attitude between two spacecraft.Then we analyze the errors in this measure system and get the error factors which impact the measurement accuracy.We νse effective data processing methods to reduce errors and improve measurement accuracy.The simulation results show that the method can reach the need of measurement accuracy of the relative position and attitude for spacecraft,it is more suitable in on-board real-time computation.
