Multisensor coordinate measuring machines that combine vision, touch and laser sensors have been used in manufacturing quality control for nearly 20 years. Like most manufacturing technologies, Multisensor systems have evolved considerably over the years as the component technologies for motion control, optics, lighting and cameras have improved.
Many still recall the early days of multisensor systems when the primary sensor worked well, but the additional sensors—sometimes added almost as an afterthought—offered limited capability and poor accuracy.
