1.Exact positioning: It can ensure precise spatial positioning during the scanning process. Through specific patterns or shapes, it helps the machine to accurately capture the 3D coordinates of the object and thus create a fine 3D model. 2.Stability during scanning: They not only improve the accuracy of scanning but also the stability of the scanning process. They provide a reliable reference point for the scanner, ensuring the accuracy of the scan results even in complex or dynamic scanning environments. 3.Optimize scanning efficiency: By reasonably arranging the marker points, the scan data can be identified and processed faster, simplifying the data alignment and splicing steps in the scanning process, thereby improving the overall efficiency of scanning and shortening the scanning cycle. 4.Multiscenario application: Flexible design, whether it is fine scanning of small objects or rapid modeling of large scenes, marker points can play an important role in meeting the needs of different fields of 3D scanning technology.
