The offset angle on parachute deployment is an important parameter to evaluate its performance. In this paper, the principle of space constraint is applied to design a motion parameter measurement method based on monocular vision with high-speed camera. And an intelligent real-time tracking algorithm based on image features is proposed to obtain images of the parachute during the deployment process. The realtime position and the offset angle of parachute are achieved by this method in flight test, which provides a reliable and effective means for the design and improvement of the parachute.
