Driving apparatus for three-dimensional scanning system and three-dimensional scanning system for computer-aided tooth modelling using the same

摘要

The 3D scanning system includes an image detector which extracts image data of a tooth plaster model, a four-axis drive which alters the position and posture of the tooth plaster model measured by the image detector, and a controller which controls the drive to alter the position and posture of the tooth plaster model, in order to measure the tooth plaster model using the image detector. The four-axis drive secures three kinds of the degrees of freedom such as tilt, rotation and main rotation with respect to a table jig on which a tooth plaster model is mounted and one kind of the degree of freedom such as linear driving for position setting. Accordingly, the posture of the tooth plaster model can be transformed into any posture, to thereby heighten a scanning automation rate, and to thus achieve measurement efficiency.
