Abstract

Schlieren photography is normal device in wind tunnel. It records varying density of flow and also shows the attitude of model. In this paper, a method is proposed to estimate the model attitudes through matching the projection drawings of 3D digital model with the schlieren photography and high speed camera image. A simulation experiment is also designed to test the method. The results show that the maximum error less than 0.1°. We also use the method to deal with the wind tunnel test data, and experimental results show that the proposed system can meet the demands of the wind tunnel test.
