This paper presents how visual SLAM and AR interfaces are integrated for inspecting the floor layouts, which is a standard stage in building a semiconductor fabrication plant (commonly called a fab). The proposed system supports multiple inspectors working in a large fab floor through client–server communications. The inspectors/clients scan the fab floor using smartphones to construct the floor map collaboratively, and then, its discrepancy from the given floor plan is checked by the server. The inspection results are broadcast to all clients and visualized via AR to help the inspectors move to unscanned areas. The experiments made with the proposed system show its accuracy and efficiency. By solving a real-world industrial problem, the proposed system proves the benefits that can be brought by integrating collaborative SLAM technique and AR-guided navigation interface.

用于地板布局检查的协作 SLAM 和 AR 引导导航

本文介绍了如何集成视觉 SLAM 和 AR 界面以检查地板布局，这是构建半导体制造工厂（通常称为晶圆厂）的标准阶段。提议的系统通过客户端-服务器通信支持在大型工厂车间工作的多个检查员。检查员/客户使用智能手机扫描工厂车间以协作构建平面图，然后服务器检查其与给定平面图的差异。检查结果广播给所有客户，并通过 AR 进行可视化，以帮助检查员移动到未扫描的区域。用所提出的系统进行的实验表明其准确性和效率。通过解决现实世界的工业问题，
