数字技术，包括手持式激光扫描仪和定位系统，正越来越多地引入建筑市场，并有可能提供实时数据，以创建建筑信息模型（例如施工图和竣工图）。针对这些技术的独特优势，本文确定了植入这些技术的挑战和机遇，以创建多维信息建模的基础上更新的数据从施工对象。本文的结果将基于一个拟议框架的实施，以帮助将来自高级扫描仪的原始3D点云半自动转换为紧凑，语义丰富的模型，以帮助更新施工图纸和开发竣工模型。一对先进的激光扫描仪已经部署在一座教育大楼内，并扫描了一个地板作为样本，以收集数据。此外，进一步的数据收集使用新的定位系统，以生成更新的数据，从目标和劳动力在样品区工作。研究结果表明，移动的激光扫描仪和新型定位系统是更新数据的有效工具，以帮助施工和维护管理人员修改图纸和使用更新的多维模型，并且比现有技术便宜约50%。结果发现，使用移动的激光扫描仪的实用框架，使施工管理人员能够获得更新的信息，从复杂的对象，使用实时通信系统。该研究为了解在建筑中实施先进技术和物联网的可能性迈出了一步，并协助开发用于建筑目的的施工图修订模型。
Digital technologies, including hand-held laser scanners and locating systems, are being increasingly introduced to the construction market and have the potential to provide real-time data to create construction information modeling (e.g. shop drawings and as-built). Focusing on the unique advantage of these technologies, this paper identifies the challenges and opportunities for implanting such technologies to create multi-dimensional information modeling based on updated data from construction objects. The results of the paper will be based on implementation of a proposed framework to assist in semi-automated conversion of the raw 3D point clouds from advanced scanners into a compact, semantically rich model aiding in updating construction drawings and developing as-built models. A couple of advanced laser scanners have been deployed within an educational building and have scanned a floor as a sample in order to collect the data. In addition, further data was collected using novel positioning systems, to generate updated data from objectives and labor working in the sample area. The findings show that mobile laser scanners and the novel locating system are efficient tools for updating data to assist construction and maintenance managers to revise the drawings and use updated multi-dimensional models, and are about 50% less expensive than the current technologies. It was found that the practical framework using mobile laser scanners enables construction managers to acquire updated information from complex objects, using a real-time communication system. The study provides a step towards understanding the possibility of implementing advanced technologies and internet-of things in construction, and assisting in developing a shop drawing revision modelling for construction purposes.
