ACQBUILT Inc. is a leader in North America in panelized construction, operating a state-of-the-artindustrialized panel production facility in Edmonton, Alberta. Using advanced technologies and amanufacturing-based approach, the company carries out homebuilding operations from design andprefabrication to delivery and onsite assembly. Leading edge technologies and methods employed in thisprocess include in-house structural design, the use of engineered wood products from top-end manufacturers,high-precision computer numerical control machinery, engineered permit-ready drawings, all leveraging thebenefits of installation and prefabrication within a climate-controlled and safe manufacturing environment.However, at present quality control at ACQBUILT is a manual process. The quality control personnel manuallycheck every wall and floor component and match the actual wall to the drawing to identify defects. This is atime-consuming process that is subject to the possibility of human error.The proposed research project will address the problem of automated inspection of panelized building productsusing computer vision technology. The research team will develop a prototype system to support (and possiblyfully automate) the quality control process. The system will be equipped with a camera, data storage, andwireless communication technology. In addition, the system will be equipped with an RFID reader foridentification of inspected products. It will also include data management and communication to facilitateaccess to captured images and remote control of the inspection process.

ACQBUILT公司是北美面板建筑领域的领导者，在艾伯塔省埃德蒙顿运营着最先进的工业化面板生产设施。该公司采用先进的技术和以制造为基础的方法，从设计、预制到交付和现场组装，开展住宅建设业务。在这个过程中采用的尖端技术和方法包括内部结构设计，使用来自高端制造商的工程木制品，高精度计算机数控机械，工程许可准备图纸，所有这些都利用了在气候控制和安全的制造环境中安装和预制的好处。然而，目前ACQBUILT的质量控制是一个人工过程。品管人员手工检查每个墙面和地板构件，并将实际墙面与图纸相匹配，以识别缺陷。这是一个耗时的过程，容易受到人为错误的影响。本研究计划将解决使用电脑视觉技术自动检测板式建筑产品的问题。研究小组将开发一个原型系统来支持（并可能完全自动化）质量控制过程。该系统将配备摄像头、数据存储和无线通信技术。此外，该系统将配备RFID阅读器，用于识别被检查的产品。它还将包括数据管理和通信，以方便访问捕获的图像和远程控制检查过程。
