1、Specifications and Features: Including 8 sheets, a total of 800 dots, single inner diameter of 3mm and outer diameter of 6mm. It has the features of high reflection, tear resistance, waterproof and sunscreen, good ink absorption, and repeatable bonding.2、Working Principle: The 3D scanner markers use bright reflective film, and a layer of reflective glass microspheres is adhered to the finish of the PET film in an aluminum plated manner, to reflect the specific sizes of the point according to the hollow printed circle.3、High Accuracy Scanning: These marking points have undergone rigorous testing and verification, providing accurate and reliable data for applications such as 3D scanning, reverse engineering, metering, and inspection.4、Convenient to Use: These reflective marking dots are designed with adhesive foil, user friendly, easy to apply and remove. The alignment during the scanning process ensures excellent data and reliable reference points.5、Applicable Scenarios: These dots are suitable for 3D scanner in the field of motion information collection, which can reflect the light emitted by data devices. The system processes the received data to achieve fixed point processing.
