Cognex Deep Learning is ideal for visually inspecting containers for defects before they are sealed and shipped. The defect detection tool can be trained on a small set of images of cartons properly filled with the correct number of tea bags. The defect detection tool can then identify any anomalies in the carton, including misalignment, quantity, orientation, or errors in visible strings and labels. The identified cartons can then be sent back to correct the errors and repackaged.
