Point Cloud Isolation

Point Cloud Isolation is the classification or segmentation of point cloud data. In simple terms, isolation of point cloud data is assigning scan points to separate layers, layers we refer to as Vertex Groups. Systems such as piping, equipment, walls, floors, and ceilings can all be separated into their own groups. Any item no matter how large or small can be placed into a separate group. These groups allow each item to be turned on and off independently. Each item can be also be exported as a separate entity apart from other points in the laser scan. The result of isolation is increased productivity, reduced scan noise, and a clean no clutter point cloud when modeling with scan data.

The isolation process of scan points is simple. First we start with a low error scan registration. Registration is the process of stitching each scan to it's neighboring scan's coordinates, and low error means the scans are registered together as one, usually within a tolerance of no more than 2 mm per 100 feet of distance. Next we determine each item or component that is to be isolated or individually "layered" and the process of assigning these points into their own layers begins. On average the isolation process takes 2 to 3 days, but could be longer for large or complex projects. Once isolation is completed, each item can be individually exported as scan data, and brought into a CAD program as an overlay for scan data modeling. For example: structure, piping, equipment, etc., can be imported independently into your CAD software.
