Patent ID: 8031331

Claim:
A coordinate measurement apparatus, comprising: at least one optical distance measurement device ( 200 , 300 ) for measuring the distance to a measurement aid ( 5 ) movable in space, and with a first measurement and control loop for tracking the measurement aid ( 5 ), a zoom camera ( 106 ) which is rotated with respect to at least two axes, with a zoom objective and with a second measurement and control loop for keeping constant the size of an image of the measurement aid ( 5 ) on an optoelectronic image converter ( 107 ) of the zoom camera ( 106 ), and an overview camera ( 104 ) for the coarse localization of the measurement aid ( 5 ), wherein the overview camera ( 104 ) has an aperture angle of 10° or more, wherein light exit optics and light receiver optics ( 101 , 102 ) of the distance measurement device ( 200 , 300 ), the zoom camera ( 106 ) and the overview camera ( 104 ) are arranged on a common carrier ( 1 ) which is rotatable with respect to at least two axes (A, Z), and wherein the optical axis ( 112 ) of the distance measurement device ( 200 , 300 ) and the optical axis ( 112 ) of the overview camera ( 104 ) run coaxially outside the coordinate measurement apparatus.
