![]() While the imagery quality typically isn’t as good as photogrammetry, this method is preferable for accuracy, particularly in hard-to-reach, complex areas of a facility. The data points are then positioned together to create a ‘point cloud’ and a navigable 360° photo tour. This LIDAR-based method captures data by running laser scanners from several positions in a facility. Usually used by the surveying industry, they do this with laser technology but is not specifically laser scanning. LIDAR is the overall process of using light to measure the distance to a predetermined target. The software uses this information to align the pictures and assemble a virtual and navigable 3D model of the space. A technician takes multiple photos from different angles around a space and captures the objects in it, then a computer algorithm processes the images to find similar pixels in the photos. Depending on requirements, a team may employ one or more of these on a project. There are several methods for capturing data to produce a 3D model. ![]() ![]() What are the different reality capture tools? ![]()
