During automatized manufacturing processes numerous elements are assembled together. With presence verification machine vision solutions, inspection of presence of components is automatized. Individual pieces of complex assemblies can be inspected, detected and classified according to requirements of production processes. Advanced in-house developed AI technology combined with state of the art hardware ensures for successful presence/absence verification for various applications in automatic manufacturing lines. With accurate detection of possible missing components, quality of final products is assured without the need for manual inspection. Manufacturing becomes faster and error free, therefore providing fast returns on initial investment.
