Wind tunnel free flight test model pose measurement system and measurement method

The invention discloses a wind tunnel free flight test model pose measurement system. The system comprises an on-site pose capture subsystem, a remote pose resolving subsystem and a model recovery subsystem. The on-site pose capture subsystem is used for measuring the angular velocity and the acceleration of a wind tunnel free flight test model by utilizing an inertial sensor; the remote pose resolving subsystem is used for resolving the angular velocity and acceleration data of the wind tunnel free flight test model measured by the on-site pose capturing subsystem in real time or off line toobtain the pose information of the wind tunnel free flight test model; and the model recovery subsystem is used for recovering the wind tunnel free flight test model and the on-site pose capture subsystem when the test is finished. The invention further discloses a measurement method of the measurement system. According to the invention, the problems that a traditional high-speed photographing method for the wind tunnel f
