一种基于机器视觉的平面光波导器件封装手动耦合系统

对平面光波导器件封装手动耦合系统进行了改进，增加了3个黑白摄像头，3张AV转USB采集卡，通过采集卡采集对准图像，利用LabVIEW8.2和IMAQ vision软件编程，将图片进行BCG调节、反转、闭合、边缘提取、手动阈值、形态学变化、直线拟合等一系列处理和识别后，实现了对光波导分路器与输入、输出光纤阵列的平行度和像素距离的检测，以一个熟练工封装132路平面光波导来说平均节省了对接封装时间10 min，减少了操作者的劳动量，减小了对准损耗，减小了人为误差。

Manual-align system for packaging planar optical waveguide based on machine vision

The manual-align system for packaging planar optical waveguide was improved with 3 monochrome cameras added, as well as 3 AV to USB capture cards, through which the align images could be gathered. In order to achieve the parallelism detection of the waveguide splitter with the input and the output of optical fiber array, by using the LabVIEW8.2 and IMAQ vision software programming, a series of processing and identification including image brightness contrast-gamma(BCG) adjustments, reverse, closing, edge detection, manual thresholding, morphological changes and linear fitting were carried out. It was proved that this system could save 10 min of the packaging time on average taking the 1×32-channel planar optical waveguide by one journeyman for example, reduce the amount of labor of the operator and the alignment loss, as well as the human error.
