It is an inspection method developed by ViSCO Technologies. The method of image subtraction (the difference between a standard pattern and an object of inspection) has been developed to enable visual defects such as flaws, dirt, and foreign matter to be stably detected and inspected.
By registering several non-defective models, DefFinder® enables the performance of inspections that absorb slight variations in non-defective products.
Several non-defective models are registered, and a standard deviation image is used as the threshold
Highly accurate, and can handle changes in rotation, scale, and more
