中文摘要：

介绍了OpenCV开源库在核数据谱线数据处理中的应用，使用OpenCV实现了谱线光滑、寻峰，以及卡尔曼滤波常用的谱处理方法。对492条256道谱线的NASVD算法的测试的结果表明，使用OpenCV方法的运算时间仅约为传统C＋＋方法的1／3，大大提升了数据处理的效率，在核数据处理中具有很好的应用前景和价值。

英文摘要：

This paper deals with the utilization of OpenCV open-source library in nuclear data processing, discusses the realization of the smoothing of OpenCV-based spectrum by several different kinds of methods and Kalman filter, and describes the OpenCV-based peak-finding method. A test of NASVD algorithm indicates that in large matrix data operation, the cost of OpenCV method is about 1/ 3 that of the traditional method. It is concluded that OpenCV can increase the efficiency of data processing and hence has a good appli- cation prospect in the field of nuclear data.
