利用CCD实测数据恢复弹形的方法

根据线阵CCD的工作特性,通过对弹丸CCD试验数据进行分析,提出了一种完整的弹丸图像恢复方法,包括阈值法提取数据、二维自适应除噪滤波、样条函数曲线拟合、微分边缘识别等。应用表明该方法具有简单、稳定、可靠、精度高的特点,在弹形恢复中取得了满意的结果,为测定弹丸飞行参数奠定了基础。

Bullet image rebuilding methods based on data acquired from linear CCD

The complete bullet image rebuilding methods are presented,on the basis of the working principle of linear CCD,through analysis of bullet image data.They are some new methods,concluding frame subtract,wiener,spline fit and differential method to recognize edge,which have the characteristics of simplicity,stability,credibility and accuracy.It is demonstrated that these methods are suitable for rebuilding bullet image,and lay the profound foundation of measuring flying parameters of bullet.
