What is the right method of optimizing point cloud data for developing digital models?

Point cloud data that is captured by the survey team from the existing building once it is scanned is utilized by modelers during point cloud modeling. As per the construction trends followed by AEC professionals now a days they make extensive use of BIM models for executing building projects as digital models contain high end information within them. Same formula is applied in the case of renovation, refurbishment and restoration projects so that critical information can be obtained from BIM models which can assist them in carrying out the project.

The only difference is that, information used for development of BIM models for fresh construction is created gradually by design and construction professionals throughout the project lifecycle which is included in them from time to time. However, models developed for renovation and refurbishment projects are created on the basis of the information extracted from the building. This is because, AEC professionals do not construct the entire building from the beginning but make certain changes to the existing building for overcoming the problem. Hence it becomes important for them to obtain accurate data from the existing building so that BIM models can be created for it by referring that information.

For obtaining correct data, laser scanning process is executed, which ultimately helps in getting critical information from all the interior parts of an as-built building. Comprehensive data about building geometry is acquired by survey team which is captured into point clouds which are extracted by laser beams. It is very important to integrate all the point clouds together that are obtained through different scans for acquiring detailed building geometry. This comprehensive scanned data is provided to BIM modelers for the execution of point cloud modeling services.

Once scanned data is converted into accurate files it can be utilized for executing point cloud modeling services for the sake of creating BIM modeling services. With the assistance of accurate building data, BIM modelers end up developing highly faultless models which are essential for providing correct information to architects and engineers about the project in question.
