ABSTRACT:
The invention relates to a method and a surveying system for noncontact coordinate measurement on the object surface (2) of an object (1) to be surveyed in an object coordinate system (O). With a 3D image recording unit (3), a first three-dimensional image (P1) of a first area section (S1) of the object surface (2) is electronically recorded in a first position (x1, y1, z1) and first orientation (φ1, ω1, κ1), the first three-dimensional image (P1) being composed of a multiplicity of first pixels (i1), with which in each case a piece of depth information is coordinated. First 3D image coordinates (u1i, v1i, w1i) in an image coordinate system (B) of the 3D image recording unit (3) are coordinated with the first pixels (i1). The first position (x1, y1, z1) and first orientation (1001, ω1, κ1) of the 3D image recording unit (3) in the object coordinate system (O) are determined by a measuring apparatus (4a,4b) coupled to the object coordinate system (O). First 3D object coordinates (x1i, y1i, z1i) in the object coordinate system (O) are coordinated with the first pixels (i1) from the knowledge of the first 3D image coordinates (u1i, v1i, w1i) and of the first position (x1, y1, z1) and first orientation (φ1, ω1, κ1) of the 3D image recording unit (3).
