大视场纤维丝集束检测系统

设计了一种大视场纤维丝集束检测系统。系统采用环形荧光灯均匀照射透明纤维丝,利用自主设计的高压静电分丝系统将直径为几十微米的细丝集束进行分离,采用步进电机控制摄影物镜进行两次成像,实现了大视场纤维丝的图像采集。为了减少运算量,提出采用多模板、限定搜索区域、减小搜索面积的匹配算法完成了大视场范围内的纤维丝集束图像的拼接,提出的单像素跟踪计数法很好地解决了细丝图像中分叉重叠等问题,实现了大视场纤维丝的检测和计数。测试结果表明,系统测量精度不低于93.3%,重复性平均误差不超过1%。

Detection system of fibrils collection with large field

A detection system of fibrils collection with large field was designed.The transparent fibrils were isotropic irradiated by the ringlike fluorescent lamp,and which were separated by the self-designed electrostatic dividing system.The fibrils image with large field was collected twice by the photographic lens which was driven by a stepping motor in the system.In order to reduce the total calculating amount,the stitching algorithm was proposed to accomplish the fibrils image merger in which the template numbers were increased,the searching region was restricted and the total areas were decreased.The single pixel tracking algorithm was presented to count the number of the fibrils collection,and which could solve the complex problems such as bifurcations,overlap and so on.The test result shows that the measurement accuracy is more than 93.3% and the repeatability average error of the system is less than 1%.
