Plane-based registration of construction laser scans with 3D/4D building models

“…Cloud-based registration uses features extracted from the data itself. Both registrations follow the same process which consists of two steps: A coarse alignment gives an initial approximation of the relative positioning, which is followed by a fine alignment that enhances the registration (Bosché, 2012). Both processes are well studied problems.…”

ABSTRACT:With the increasing popularity of as-built building models for the architectural, engineering and construction (AEC) industry, the demand for highly accurate and dense point cloud data is rising. The current data acquisition methods are labour intensive and time consuming. In order to compete with indoor mobile mapping systems (IMMS), surveyors are now opting to use terrestrial laser scanning as a standalone solution. However, there is uncertainty about the accuracy of this approach. The emphasis of this paper is to determine the scope for which terrestrial laser scanners can be used without additional control. Multiple real life test cases are evaluated in order to identify the boundaries of this technique. Furthermore, this research presents a mathematical prediction model that provides an indication of the data accuracy given the project dimensions. This will enable surveyors to make informed discussions about the employability of terrestrial laser scanning without additional control in mid to large-scale projects.

“…One of the most prominent publications has been the comparison of IMMS compared to Terrestrial laser scanning (TLS) in terms of accuracy and acquisition speed (Thomson et al, 2013). In this research, both the IMMS of Viametris (Viametris, 2007) and the ZEB1 from CSIRO (Bosché, 2012) are discussed. Thomson et al concludes that IMMS might have a significant impact on future workflows, but currently lack sufficient accuracy.…”

“…Bosché (Bosché, 2012) states that these resemblances present a challenging constraint for the registration process. Therefore, Simultaneous Localization And Mapping (SLAM) or automatic registration algorithms are prone to misalignment in these environments.…”

“…This should normally be performed using site benchmarks. If structural works have been successfully controlled, it is also possible to use the building structure as natural landmarks for the registration, e.g using the planebased registration approach presented in (Bosché, 2011).…”

Previous research has shown that "Scan-vs-BIM" systems are powerful to provide valuable information for tracking structural works (progress, quality, safety). However, the transferability of this capability to other construction areas such as MEP works has not been assessed so far. Comparatively, the construction of MEP systems, in particular pipes and ducts, tends to be more flexible with respect to the positioning of individual components, so that Scan-vs-BIM systems could be defeated when tracking MEP installation works. This paper presents recent results on the feasibility and performance of using a Scan-vs-BIM system to track MEP works. The approach followed is presented and then tested with two real-life challenging case studies were conducted simultaneously but totally independently in Canada and Italy. The results show that, as expected, pipes and ducts tend to be more loosely positioned than structural elements leading to a poorer performance of the Scan-vs-BIM system. Nonetheless, it appears that the system works well to assess the level of conformance of site installation works, providing valuable information for estimating emerging performance metrics like "percent built as-designed". In addition, the proposed system could also be useful to accelerate and thus reduce the cost of delivering as-built BIM models for in the case of new builds.
