Abstract

This work presents an optical inspection-guiding system for electronic board manufacturing. The system monitors in real time the mounting process of electronic components performed by an operator. It visually guides the operator through the mounting process while checking the correctness of its actions. As a consequence, mounting errors are reduced while operator comfort is enhanced. This work also introduces a novel method to generate virtual images from a few real images in order to generate enough data for model training. The proposed method is tested using 7 different descriptor combinations and 4 different classifiers. We have also collected, generated, and evaluated a component dataset of 20 different components, called ECAD. The solution was tested with 16 real scenarios, different electronic boards which are empty or full with components. Finally, a usability test was carried out with 21 different people comparing the original and proposed solutions. The propose system is advantageous since it enhances operator’s comfort and satisfaction, increases mounting speed, and reduces error ratio.

实时自动光学系统，可帮助操作员组装电子元件

摘要

这项工作提出了一种用于电子板制造的光学检查指导系统。该系统实时监控操作员执行的电子组件的安装过程。它可以直观地指导操作员完成安装过程，同时检查其动作的正确性。结果，减少了安装错误，同时提高了操作员的舒适度。这项工作还介绍了一种新颖的方法，可以从一些实际图像中生成虚拟图像，以便生成足够的数据进行模型训练。使用7个不同的描述符组合和4个不同的分类器对提出的方法进行了测试。我们还收集，生成和评估了包含20个不同组件的组件数据集，称为ECAD。该解决方案已经在16种真实场景下进行了测试，这些不同的电子板是空的还是装满了组件。最后，与21个不同的人进行了可用性测试，比较了原始解决方案和提议的解决方案。提议的系统是有利的，因为它提高了操作员的舒适度和满意度，提高了安装速度，并降低了错误率。
