在过去的几年里，使用各种数据采集方法，在自动化施工进度监控方面取得了重大进展。在本文中，我们提出了一种新的方法，这将克服某些缺陷，在现有的方法。我们的方法的基本原理是，首先，通过使用多个头盔安装的扫描仪连续获取部分竣工点云，扫描正在进行工作的位置的室内和室外场景，并记录点云，位置和时间戳。第二，合并部分的、带时间戳的竣工点云，以创建正在施工的完整4D竣工点云。第三，通过使用现有的3D BIM几何模型作为参考模型，注册来自4D竣工点云的元素，并生成4D竣工BIM。第四步是比较4D竣工BIM和4D设计BIM，以确定两种模型之间的差异。从元素的差异中，识别并报告时间进度偏差。
In the past few years, a significant progress has been achieved in Automated Construction Progress Monitoring, using a variety of Data Acquisition methods. In this paper, we propose a new method, which shall overcome certain deficiencies recognized in existing methods. The basic principles of our method are, first, to continuously acquire partial As-built point clouds by using multiple helmet-mounted scanners, which scan the indoor and outdoor scenes of locations where work is being done, and record point clouds, locations and time stamps. Second, merging partial, time stamped As-built point clouds to create a complete 4D as-built point cloud of construction in progress. Third, registering elements from the 4D as-built point cloud by using the existing 3D BIM geometry model as the reference model, and generate the 4D as-built BIM. The fourth step is the comparison of 4D as-built BIM and 4D as-designed BIM to identify the differences between both models. From the differences in elements, the time schedule deviations are identified and reported.
