Abstract

The invention provides a calibration device of a three-dimensional scanner and an intraoral three-dimensional scanner. The calibration device of the three-dimensional scanner comprises a calibration plate used for calibrating the scanner, a movement portion comprising a motor and a screw rod, and a reference portion, the screw rod extends along a first direction and is driven by the motor, a firstend of the screw rod is connected with the calibration plate in a driving manner, the motor is movably arranged on the reference portion, and a second end of the screw rod is threadingly connected with the reference portion to enable the movement portion to drive the calibration plate to move up and down and rotate during movement in the first direction. According to the technical scheme, the problem of large fitting error of the three-dimensional space during calibration processing of the scanner in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional scanning, in particular to a calibration device for a three-dimensional scanner and an intraoral three-dimensional scanner. Background technique [0002] When calibrating the original data of the 3D scanner, the conventional technical method is: let the 3D scanner collect data from the calibration plate at a specific angle and specific distance, and then fit the background reference parameters used by the software calculation when obtaining the subsequent scanned object. The above-mentioned three-dimensional scanner is used to collect data on the calibration plate at a specific angle and a specific distance, and the calibration plate / three-dimensional scanner machine is mainly adjusted by means of motor drive. [0003] Among them, when adjusting the position of the calibration plate in a motor-driven manner, it is easy to cause the following problems: the transmission mode of the convent...
