Point cloud is a collection of vertices in a 3D co-ordinate system referred as X, Y, and Co-ordinates and are usually intended to determine the external surface of the object. Point cloud scanning is a process of scanning buildings or products with the help of laser scanners following the vertice points. These equipment’s electronically calculate numerous points on the surface of an object and provides point cloud as a data file which can be later converted into BIM. Point cloud obtained can be utilized for various purposes with the inclusion of developing BIM models which aids visualization, animation, rendering and various other applications.
By means of 3D Laser Scan, one can examine the spaces in an existing building to develop electronic 'cloud' of geometrical points. The data obtained in the form of digital point cloud can then be employed to develop the geometry of the structure. These data files are then imported to a BIM Software like Revit or ArchiCAD and the materials are determined. This technology of generating point cloud and generating BIM or precise parametric Building Information Models are referred as Scan to BIM Modeling or E-BIM.
Point cloud files are incredibly huge data files usually produced by employing laser scanning and surveying. It allows end users to study, store, and index and rapidly retrieves massive data sets into the design infrastructure management procedure; generate precise designs and mapping data rapid. Besides preserving time in the design procedure, it allows innovators to capture, model, and amend complicated physical shapes like organic shapes. Intricate shapes such as a mesh could be computed automatically by the point cloud processing software. For simpler one like planes, curved shapes, cylinders, etc the operator can transform the point cloud into solid 3D shapes. These solid shapes are then imported into simulation or animation software which is then utilized to analyze the effect of environment on the project.
The point cloud 3D laser scanners employed for various engineering applications evaluate present project's status rapidly. Usually 5,000 individual points are calculated per second. Point clouds are collection of the 3 co-ordinates representing north, east and elevation, the color of the point measure and the returned intensity of the laser are gathered. It also provides project management information inclusive of place, date and time details, technicians' names, climate conditions, and scanner location. As the Point Cloud is visible on PC, it enables you to analyze and manipulate the data.
Benefits of E-BIM using Point Cloud:
1. Laser scanning rapidly capture data thus reducing the site time radically.
2. Precise and apparent scanning
3. Comprehensive Scanning of every building element rapidly
4. Laser Scanning is carried out in 3D in which Point Cloud resembles as 3D duplication of the existing building thus aids in efficient visualization the building.
