If you scan a part sitting on a turntable or base that has a rich geometry or color pattern to it, and you intend to scan multiple times in multiple positions (top, bottom, side, etc.), don’t automatically delete this base right away! When you do this, you maximize the chance your project is a success on the first try.

Using Global Registration During 3D ScanningĪn important thing to note about global registration is that it is sometimes most effective to use it first in your processing workflow, running global registrations on the individual scans before aligning them all together. You should lower this if you are 3D scanning an object with thin, repetitive features, so that frames are limited in how far they can move. It’s usually best to keep this at the default value, because it controls how far away the algorithm considers aligning data. The final option to consider is the one least used: feature search radius. You generally want to keep key frame ratio as low as possible for the sake of speed, but it is sometimes necessary to raise the key frame ratio to higher levels if the data still doesn’t fit properly with a low ratio. Think of this as the “strength’ of the algorithm, with 0.1 being considered low strength and 0.6 being considered high strength, with 1 being the maximum. The second option to consider is the key frame ratio. If your object has a color pattern to it, such as wood grain, text, or even freckles, the geometry + texture algorithm is the one to use.
All Artec 3D scanners except for the EVA Lite collect data in two layers: geometry (shape) and texture (color). The first is the algorithm: geometry only, or geometry + texture. To help you do this, global registration gives you three primary options to adjust. Global registration is essentially a pattern recognition algorithm that fits all of the frames of data within a project together as best as possible. Found within the Tools ribbon, global registration is usually one of the last steps in any given project, but its importance deserves first mention. Global Registrationīy far, the most important data processing tool for maximizing overall quality is the global registration. Here are five essential Artec Studio tools that will make your life significantly easier when processing a scan. Whether you’re new to the world of 3D scanning or have successfully created multiple models, it never hurts to refresh your skills. Mastery of these tools takes an accumulation of experience, and with that comes knowledge of pitfalls, so a little bit of determination early on can pay dividends twice as fast. Built to take your 3D scanning projects from scan to polygon-model-export, Artec Studio contains a simple and intuitive core workflow, as well as myriad branches of processing tools and elements that help you handle all of your unique and interesting scanning projects.
