National Instruments has released its Vision 7.1 Development Module machine vision software that features advanced algorithms, including geometric matching, object classification, optical character recognition and 2-D bar-code readers. Users can create vision applications that inspect, align, identify and measure objects even in poor lighting conditions. Parts can be tracked via information applied through ink jets, thermal transfer, laser etching or dot peen. Products are sorted at high speeds, and defects are cataloged. The Vision Assistant, which is included, allows engineers and scientists to prototype their applications before writing any code.
