Paper Abstract

In this paper, a joint posture determination algorithm of rocket contour line and cooperative measurement ring photographed by high-speed TV in the shooting range is proposed targeting at the complex test range environment with lot of smoke and backlight. This algorithm makes up for the shortcomings of traditional algorithms in some extreme cases. The method makes use of the relative relation between the target contour edge and the measuring ring edge and the cylindrical rocket body. Even if under the poor imaging, the method can still calculate out the information about the posture of the rocket. If the method is validated with the measured data, the difference values of the calculation results are as accurate as the calculation results of the traditional methods. However, this method is better in anti-interference and has a more extensive application scope, achieving the expected purpose.
