“…The scanner collects a ' point cloud ' , and was assembled at four locations inside the auditorium (the stage, stalls, circle and balcony). The process followed was similar to that reported previously in the literature ( Barber et al , 2006 ;Arayici, 2007 ), where a range of techniques have been used to utilise the resultant data set within architectural modelling.…”

In particular, it explores how such technology can be used as a complement to both traditional measurement and historic records, as well as in the 3D surface modelling of heritage detail. The article uses examples from cinema buildings of the twentieth century, which arguably embody both an important physical record of society and a challenge in terms of representing a complex range of historical, cultural, economic and physical data sets. The work provides an overview of visualisation techniques that are appropriate to the subject, and provides a case study taken from the city of Aberdeen. In particular, attention is drawn towards the manner in which large and physically complicated structures can be recorded rapidly, to provide a permanent record of dimensions and building form. Furthermore, the data set produced through use of a 3D scanner can be readily translated for incorporation within architectural models such as a 3D surface mesh. The article concludes that emerging technologies will facilitate the rapid collection of highly accurate information pertaining to the still intact physical structure, where still in place, but that such data must be related directly to wider contextual information so that informed plans can be formulated for future developments, including conservation strategies.

“…The geospatial data, obtained using laser scanners, serve not only for the creation of 2D and 3D models of individual objects, but also their larger sets and combinations. Examples of such studies are presented, among others, in the work of [Arayici 2007]. The edge effect, as shown in 2D representations, here too, has its impact, and that impact is felt to a greater extent.…”

SummaryThe edge effect is a measurement error resulting from the reflection of the laser beam on the adjacent walls, or by its breaking on the edges. Coordinates of points in such cases are determined by averaging the measurements in several areas, resulting in their incorrect positioning in space. Corner points are determined with the same accuracy as the other (flat) elements of the scanned object. This effect is frequently mentioned in publications, which typically state the reasons and mechanisms of the error thus occurred. However, there is a lack of specific examples, showing the impact of the edge effect on the quality and accuracy of geodetic and cartographic reports. In this paper, the authors present sample case studies of the 2D and 3D representation of the test object. The selected corner elements, as well as the vector elements fitted into a cloud of points, show the discrepancy between the breaking points in the drawing (model), and the curved surface of the point cloud. On the basis of the known geometry of the building, distances were determined between the corner points and their representatives on the cloud. In this way, we were able to determine the accuracy of corner points' presentation by means of the cloud of points, and therefore, we were able to determine the size of the edge effect in specific cases.

“…However, there are two main problems in this area. First, geometric information such as lines and surfaces cannot be easily extracted from millions of points data of objects [1], and are recommended as future research [1,4]. Second, a limited number of scanners such as terrestrial scanners are suitable for BIM [36], and the state-of-the-art technologies have not been investigated fully.…”

-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.
