Abstract:
1. A method for noncontact coordinate measurement to an object surface of an object to be surveyed in an object coordinate system, comprising: electronically recording a first three-dimensional image of a first area section of the object surface by means of a 3D image recording unit in a first position and first orientation, the first three-dimensional image being composed of a multiplicity of first pixels, with which in each case a piece of depth information is coordinated; coordinating first 3D image coordinates in an image coordinate system of the 3D image recording unit with the first pixels without use of a multiplicity of reference markings being determined; determining the first position and first orientation of the 3D image recording unit in the object coordinate system by a measuring apparatus coupled to the object coordinate system, wherein the measuring apparatus is substantially decoupled from retaining forces which act during holding of the 3D image recording unit; and coordinating first 3D object coordinates in the object coordinate system with the first pixels from the knowledge of the first 3D image coordinates and of the first position and first orientation of the 3D image recording unit.
