A concept of CAD model-based automated 3D measurement and the evaluation of its feasibility in cases drawn from industrial needs. Automated 3D measurement can be seen as comprising two steps: measurement planning and measurement execution. The concept was evaluated by implementing a graphical measurement planning tool and two automatic optical measurement systems equipped with vision systems for sensory feedback. The operation chain from CAD model-based measurement planning to comparison between the measured and designed geometries was demonstrated. Successful experiments with automatic operation controlled by the measurement plan and vision guidance were carried out and the key performance criteria were met
