Most laser scanners produce point clouds with irregular spacing – surfaces close to the laser scanner are scanned in much more detail than surfaces that are further away. This leads to huge point counts and file […]
For my job I deal with point clouds almost daily – in fact, much of my programming revolves around point clouds and how to extract information from them automatically. This means that it is very important […]
