Vision-based quality control for building manufacturing

ACQBUILD Inc.是北美板材建筑领域的领导者，在阿尔伯塔的埃德蒙顿拥有最先进的工业化板材生产设施。公司采用先进的技术和以制造为基础的方法，进行从设计和预制到交付和现场组装的住宅建筑业务。在这一过程中采用的领先技术和方法包括内部结构设计，使用高端制造商的工程木制品，高精度计算机数控机械，工程图纸，所有这些都利用了在气候受控和安全的制造环境中安装和预制的好处。质量控制人员手动检查每一个墙壁和地板组件，并将实际墙壁与图纸相匹配，以确定缺陷。这是一个耗时的过程，而且可能会出现人为错误。拟议的研究项目将解决使用计算机视觉技术对镶板建筑产品进行自动检测的问题。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，该系统还将配备RFID阅读器，用于识别受检产品。该系统还将包括数据管理和通信，以便利获取捕获的图像和远程控制视察进程。

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.
