Our objective was to perform a terrestrial scan of the building found at 4150 Concours St Suite 100, Ontario, CA 91764 & prepare the data for visualization. This objective can be achieved by two methods: conducting a terrestrial scan of the structure & preparing the point cloud data in Trimble RealWorks. By setting up six control points, a Trimble TX8 laser scanner can be used to scan the surrounding landscape & structures to generate a point cloud that is comprised of over ~1.5 billion points. Then, six .las files, one file for each respective control point, are loaded into the Trimble RealWorks software.  

              Once the .las files are loaded, RealWorks can be used to georeferenced the point cloud. Georeferencing allows for the transformation of the project to an external coordinate system if the coordinates of three or more points are known. 1.5 billion points are a monumental amount to work with, so in order to make the point cloud more manageable, a segmentation is conducted. Segmentation allows for the removal of any points that may be deemed unnecessary for the project, essentially reducing the number of points that will be used. The segmentation removes as much of the landscape surrounding the structure as possible, leaving only the structure’s points intact and reducing the number of points from ~1.5 billion to a more manageable ~60 million points. Once the point cloud has been georeferenced & segmented, it is ready to be exported in US Survey feet in preparation for the visualization team to visualize in Autodesk Recap & Revit.
