Introduction to Oral Scanning Positioning Calibration Plates / Irregularly Shaped Calibration Plates
Oral scanning positioning calibration plates and irregularly shaped calibration plates are mainly used for precision calibration and spatial positioning of oral digital scanning, 3D vision, dental CAD/CAM, and oral scanning equipment. The calibration plate provides a stable and accurate spatial reference benchmark for the scanning system through high-precision machining of geometric structures and feature markings, enabling parameter calibration, spatial positioning, and accuracy verification of the scanning equipment. Irregularly shaped calibration plates employ non-planar, multi-angle, or three-dimensional structural designs, providing rich feature information in different directions, which is beneficial for improving the scanning system's ability to recognize spatial position, posture, and three-dimensional geometric relationships. Oral scanning positioning calibration plates can be customized according to the structure and calibration requirements of the oral scanner, making the calibration process more suitable for actual use scenarios.
