3" or 1/4" 3D point cloud data (nothing to do with storage or computing clouds) recorded by high-speed laser measuring devices are the new norm for data collection, inside and out. They are used to produce large-size scans of roads, buildings, and manufacturing plants. Versions are available also for small size scans, such as of just-manufactured parts and car bodies. The problem of raster has dogged it since it was invented: the higher the resolution (ie, more accuracy), the bigger the file size. For 2D images, like photograph, the increased file size is by the square: twice the resolution make... Read more →
