GlueDotInspect

The GlueDotInspectTool measures the position and fill level of individual adhesive dots in a defined area. Position and detected glue area can be compared with a trained reference. For this purpose, the area of each dot covered with adhesive is determined with a CogBlobTool and compared with the corresponding area in the training image. The deviation of the area size and the area center of gravity is evaluated.
