Markers ensure high accuracy and repeatability of results. They solve difficulty during scanning and difficulty attaining high accuracy on large object Easy to scan: Reference point markers for 3D scanning are very useful when you want to scan smooth objects, such as cups, cars, sculptures, or anything with a smooth surface. Markers help 3D scanners use these “high-contrast”objects to determine its location. Markers are usually applied on (or near) the object being scanned to increase accuracy and repeatability of 3D data. Markers reduce the possibility of losing tracking during scanning.By using markers, you do not lose tracking during scanning,so the process is faster and predictable.They also ensure high accuracy and repeatability of results., Manufacturer: SOYWIM
