But point clouds are often very large files – so large in fact, that they require specialist computers to work with. This is arguably one of the most important functions of point cloud software. Facilities managers can also use point clouds to get accurate floorplans of their buildings, and to help them plan projects – for instance, rearranging machinery on a factory floor for manufacturing a new product. Construction firms may also want to feed point cloud data into their BIM plans, so they can compare as-built conditions with their plans as construction unfolds. For AEC professionals, for instance, point cloud data is incredibly useful in 3D design tools as the basis for their designs. #POINT CLOUD DATA SOFTWARE#Point cloud software can also provide a way for you to use point cloud data in other software applications. Again, point cloud software is needed to do this. This is especially important if you are stitching multiple point clouds together.īecause every point has data about where it is in space, you can also use point clouds to take incredibly accurate measurements of a space, calculate volumes, and more. Firstly, before point cloud data can be viewed it must be ‘registered’ so that the data all lines up and looks like the object or space you have scanned. Point clouds require specialist software to view and manipulate then. On their own, point clouds don’t do much – you need point cloud software to extract value from that data. Viewed from a distance in point cloud software, they look a bit like impressionist paintings – and up close, you can see all the individual points that make up the scan. Millions of points make up a point cloud – billions, if you are scanning a large building or complex. Together, these points form an image of whatever you had scanned. They are datasets that are made up of ‘points.’ Each point represents something – a part of a wall, window, or wire, for instance – and the point contains information on where that part is in space. Point clouds are, in essence, very simple. They look pretty simple – but in truth, there’s a lot to understand about point clouds if you’re to get the best value out of them, and by extension your investment in 3D scanning tech. If you have already tried it out, you’ll no doubt have seen the scans you can generate – also known as point clouds. #POINT CLOUD DATA PRO#A range of scanners exist, from tripod-mounted to handheld scanners the latest iPhone 12 Pro even includes 3D scanning technology in the phone’s camera, though they aren’t detailed enough for more than quick checks on small elements of a project. It’s a great time to try 3D laser scanners as they are becoming much more widely available and affordable on the market. #POINT CLOUD DATA DOWNLOAD#If you are doing environment modeling, meshing, etc., you can directly download point clouds in global coordinates.Have you tried out 3D scanning tech yet? It’s well worth a look for anyone who is in the architectural, engineering and construction space, as well as facilities managers and a whole range of other industries. #POINT CLOUD DATA REGISTRATION#Once you have selected the datasets you need, you can download files in local reference frame if you want to test registration algorithms and compare your result with pose_scanner_leica.csv, which contains the ground truth information. To easily view this type of file, we suggest to use Paraview ( ) because it is freely available for Windows, Mac and Ubuntu users and it is well supported by Kitware.Īnother advantage is that Paraview can handle large point clouds with information on points faster than Matlab. Then, go to the section Downloads → Visualization Files and download the file globalMap.vtk. There, you will be able to have a look at different screenshots and pictures of the scene, which will help you to understand better the abstract point clouds. If you are not sure, we suggest to start with structured datasets as they are easier to visualize. You first need to determine which data suit your needs.įor that, pick up a dataset in the table below based on your requirements. ![]()
