1.Accurate Positioning It can ensure accurate spatial positioning during the scanning process. Through specific patterns or shapes, it helps the machine accurately capture the 3D coordinates of the object, creating a fine 3D model. 2.Scanning stability: not only improve the accuracy of scanning but also the stability of the scanning process. They provide a reliable reference point for the scanner that ensures the accuracy of scan results even in complex or dynamic scanning environments. 3.Optimize scanning efficiency: The sensible location of the marker points allows scan data to be identified and processed faster, simplifying data alignment and splicing steps in the scanning process, improving overall scanning efficiency and shortening the scan cycle. 4.Multi Scenario Application Flexible design, whether it is fine scanning of small objects or fast modeling of large scenes, marking points can play an important role to meet the needs of different areas of 3D scanning technology.
