Point cloud today is in high demand among architects, engineers and the construction industry. Data is collected using a 3D laser scanning instrument. This involves gathering a large number of points defined by a coordinates system with high precision for surfaces or objects. After collection, the raw data is imported into the Point cloud modelling software and converted into a readable file. The collected data allows you to view the as-is condition of the building and create 2D and 3D CAD plans.
Through this advanced method of capturing data, 3D laser scanning finds application in a wide range of industry fields. 3D scanning has also been used for creating 3D modelling of accident scenes.
Collapsed structure, bridges: A scanner is a great solution from a safety point of view, since this allows recording data from a safe distance without interfering with the ‘’object’’. Without a scanner it would be more complicated to view the actual scene of an incident or the condition it is in. The advantage of this software is that the data can be reviewed and investigated at any point, whether in one or two months’ time or at a later time.
The archaeology discipline: It finds important applications for this software as well. Data is captured in as-is condition with coloured cloud points, which can then be used for recoding and archiving historic fabrics, etc.
Monitoring movement: The scanner gathers data with high accuracy, contouring the surface of buildings and structures. By repeating the scan every few months and overlaying one scan over another, any movement/change can be detected.
Architects and engineering: Point cloud can be used to create 2D plans and elevations, or to create sections of different parts of a building or even for 3D modelling, studying the condition of an object (building) or for calculating volumes. There are several other applications, where scanning is a very relevant and useful solution. The shape and condition of stonework, corbels, heritage and listed buildings can be enhanced and reproduced to a large scale.
Efficiency and effectiveness
Time on site is reduced and this is important when collecting data for some premises where time available is limited (for example offices, residential care homes, schools). Additional information can be extracted without the necessity of returning to site, thereby reducing the cost of site work and processing to the minimum.
The data can be manipulated for use according to the requirements of the project. In architecture and engineering, 3D models of a building or pipes can be created, or while filing documents for historic buildings and listed buildings, giving you a real image without the risk of missing information on field, thus keeping errors to a minimum.
