Two-Step Alignment of Mixed Reality Devices to Existing Building Data

With the emergence of XR technologies, demand for new time- and cost-saving applications in AEC industry based on these technologies is rapidly increasing. Their real-time feedback digital interaction field makes systems very well suited construction site monitoring, maintenance, project planning, so on. However, continuously changing environments sites facilities requires extraordinary robust dynamic data acquisition to capture update built environment. New devices already have hardware accomplish tasks, but framework document geolocate multi-temporal mappings a environment still much subject ongoing research. The goal this research is, therefore, study whether Lidar photogrammetric can be adapted process sensory align multiple time series same coordinate system. Given sometimes drastic changes sites, we do not only use also any preexisting remote sensing as-is or as-designed BIM aid registration. In work, specifically low-resolution geometry image matching Hololens 2 during consecutive stages construction. During experiments, constructions are captured registered. experiments show that XR-captured reliably registered datasets with an accuracy matches exceeds resolution data. These results indicate method excellent way generic wide variety existing reference
