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。

Aiming at the problem of large knitting pitch density or small density in braiding process of superconducting wire braided wire sheath, the coordinates of each matching point are obtained by template matching and the matching coordinate information of nonconformity is removed. Analyze and find the pitch between each matching target, remove the maximum and minimum, and get the average pitch; judge whether it meets the set requirements, do not meet the requirements of the image secondary data analysis, the final access to the existence of pitch Density or density of small conclusions. After many experiments on real-time images, the accuracy of the obtained results can reach more than 95%, which can reflect the density of the braided wire.
