Feature:1. SIZE AND QUANTITY: Inner diameter is 3mm, outer diameter for 6mm, each sheet contain 56 single point mark, possess high reflective brightness, tear resistant, water proof and sunscreen, good ink absorption, repeatable fit2. HIGH ACCURACY SCANNING: These 3D scanning markers are used for featureless objects, suitable for reverse engineering, metrology and inspection. Alignment during scanning ensure excellent data and reference points3. EASY TO USE: The 3D scanning reflective markers are designed with adhesive foil, which is easy to apply and remove, user friendly without worry, ensure a seamless experience for professionals and beginners alike4. APPLICABLE SCENARIO: Used for 3D scanners in the field of motion information acquisition(such as three dimensional motion catch, three dimensional gait analysis, etc.), the scanning markers can reflect the light emitted by the device (usually infrared light) reflected by the data device to receive, and the system processes the received data to achieve fixed point processing5. WIDE APPLICATION: 3D scanner tracking point is easy to pick up, 3D optical tracking mark is an indispensable auxiliary position tool and calibration tool in optical mapping, machine viewing and other fieldsSpecification:Item Type: 3D Scanning MarkersMaterial: PET and reflective filmSize: Inner Diameter: Approx. 3mm / 0.12in, Outer Diameter: Approx. 6mm / 0.24inThickness: 0.15mmQuantity: 10 Sheets(56pcs per sheet, 560pcs in total).Package List:10 Sheet x 3D Scanning Markers Stickers(56pcs per sheet)
