超导编织线的编织密度检测系统设计

Design of braided density detection system for superconducting braided wire

针对超导线材编织线护套在编织过程中出现的编织节距密度大或密度小的问题,利用模板匹配的方式获得各个匹配点的坐标,并对不符合的匹配坐标信息进行剔除;利用数据分析求取各个匹配目标之间的节距,去除最大值和最小值,求得平均节距;判断其是否满足设置要求,对不满足要求的图像进行二次数据分析,最终获得是否存在节距密度大或密度小的结论。经过对实时图像的多次试验,获得的结果准确度可以达到95%以上,能够反映出编织线的稀密程度。

In the braiding process of superconducting wire, the problem of large or small pitch in the braid, using the template matching method to obtain the coordinates of each match point, Eliminate the mismatched matching coordinates information. Through the data analysis and calculation, obtain the pitch value between each matching target, remove the maximum and minimum values and then calculate the average pitch. Whether the pitch satisfies the setting requirement,if the second data analysis of the image does not meet the requirements, and finally determine whether there is a large pitch density or low density. Through many experiments of real-time image, the accuracy of the results achieved above 95 % ,which reflect the pitch density of superconducting braided wire.
