METHOD AND DEVICE FOR OPTICAL SCANNING OF THREE-DIMENSIONAL OBJECTS BY MEANS OF A DENTAL 3D CAMERA USING A TRIANGULATION METHOD

摘要

PURPOSE: A method and a device thereof are provided to automatically detect the moment when shake is generated by directing the generation of camera shaking in real time. CONSTITUTION: A 3D camera(1) for dental clinic visually scans a 3D object(2). The camera is operated according to triangulation procedure. The camera obtains a plurality of images(30) about the object. At least one comparison signal(45-47) is formed based on at least two images which are obtained with the camera. At least one camera shake index(50) is determined based on at least one comparison signal.
