Abstract:In order to measure the position and attitude of the target in wind tunnel experiment, a co-operation target image acquiring method is proposed for high-speed targets by utilizing principles of the machine vision and the optimization of lighting source. Base on the CCD model, the effect of the characteristics of the camera, light source and the co-operation target on the image quality is analyzed firstly. Then, the signal-to-noise ratio between co-operation target and background is employed to detect the image quality of high-speed targets. The distribution rules of spatial brightness and SNR image of micro glass beads reflective material marker are derived for monocular camera and binocular camera. Finally, experimental results indicate that the image acquiring method presented is effective for measuring the position and attitude of high-speed target in the wind tunnel experiment. ? 2013 IFSA.
