1. Method for optical acquisition of the three-dimensional geometry of objects, in particular teeth ( 4 ), with a scanner ( 14 ), which has a scanning head ( 13 ), whereby the three-dimensional geometry that is acquired in a virtual three-dimensional space ( 1 ) in the course of scanning is noted, wherein in the course of scanning, positions of a defined scanner geometry ( 2 ) of the scanner ( 14 ), in particular of the scanning head ( 13 ), are noted relative to the object ( 4 ) that is acquired, in that, moreover, an area ( 6 ) in which the defined scanner geometry ( 2 ) is or was located is determined, and in that the determined area ( 6 ) is marked, for example as “empty,” in the virtual space ( 1 ).
