Method and device for measuring attitude of parachute in wind tunnel test and medium

The invention discloses a method and device for measuring the attitude of a parachute in a wind tunnel test and a medium, and relates to the technical field of low-speed wind tunnel tests. Based on a motion capture system, the lower end of the parachute is fixed to a preset fixing point on a branch, and the branch is fixed to the center line of the wind tunnel ground; establishing a three-dimensional space coordinate system of the motion capture system by using a first camera arranged outside an observation window on the side wall of the wind tunnel; a second camera arranged in the wind tunnel is used for shooting the motion trail of a mark point at the top end of the parachute when the parachute moves to obtain a motion trail image of the mark point; and determining position information of the mark point in the three-dimensional space coordinate system according to the motion track image and the three-dimensional space coordinate system, and determining the attitude of the parachute according to the position
