Use flow field experimental platform to simulate wind tunnel environment

makes a model aircraft as detection object and adopts a video image-based method for flight attitude detection using two cameras. The model aircraft targets in the two path video images are extracted respectively based on its color feature

then straight line extraction approach is employed to obtain parameters of straight lines in model aircraft target

and roll angle and pitch angle attitude are calculated through the change of parameters of straight lines. Compared with datas of attitude and heading reference system（ AHRS） MIN—IVA900

the maximum deviation of the detection method is less than 1°

and that indicates the consistency of flight attitude detection result.
