The Machine Vision Laboratory Test Bench is a software add-on for LabVIEW. With this add-on, you can perform detection of the location of an object's boundaries and the presence of discontinuities. You also can performpattern matching for alignment, gauging, and inspection. The Machine Vision Laboratory Test Bench helps you obtain geometrical measurements through the dimensional measurements tool; read meters, seven segment displays, barcodes, and 2D codes; and read textand characters in an image with the optical character recognition (OCR) feature.
