The present invention relates to a coordinate measuring machine CMM (22), comprising a carrier (12, 30, 31) as a support and positioning structure for an end-effector (40) as a target, the end-effector (40) being movable in at least three degrees of freedom and positionable by the carrier (12, 30, 31), a stationary metrology table (35) as a support for a possible target object, and a control unit controlling the moving of the end-effector (40) by the carrier (12, 30, 31). The CMM further comprises at least one, in particular at least two, imaging detectors (33) for measuring and determining in six degrees of freedom a position of the possible target object, and an analysing unit for processing electronic signals and/or data delivered by the imaging detectors (33). According to the invention, the imaging detectors (33) are firmly mounted to the metrology table (35), mechanically de-coupled from the carrier (12, 30, 31).
