DEVICE, METHOD AND SYSTEM FOR GENERATING DYNAMIC PROJECTION PATTERNS IN A CAMERA

Abstract:

A device, method and system for utilizing an optical array generator to generate dynamic patterns in a dental camera for projection onto the surface of an object, while reducing noise and increasing data density for three-dimensional (3D) measurement. Projected light patterns are used to generate optical features on the surface of the object to be measured and optical 3D measuring methods which operate according to triangulation principles are used to measure the object.
