1. A method for optical acquisition of a three-dimensional geometry of objects with a scanner ( 14 ) that includes 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 scanning head ( 13 ) of the scanner ( 14 ) are noted relative to the object ( 4 ) that is acquired, wherein an area ( 6 ) in which the defined scanner geometry ( 2 ) is or was located is determined, wherein the determined area ( 6 ) is marked in the virtual space ( 1 ), wherein the scanner geometry ( 2 ) of the scanning head ( 13 ) of the scanner ( 14 ) is defined before acquisition, and wherein the scanner geometry ( 2 ) is a same size or smaller than the scanner ( 14 ) or scanning head ( 13 ).
