Let's look at the Stain mode algorithm that supports appearance inspections of various targets.Computer Register 10 Color rotogravure, gravure type heat Transfer Film Printing Machine, mechanical shaft or shaftlessġ0 colors ( there has 3-10 printing colors can be chosen)ħ00-1050mm (1250BⅡ:900-1250mm / 1500BⅡ: 1150-1500mm) There are a number of inspection modes, and the Stain mode is the most commonly used. The next topic is related to software: basics of appearance inspection. Inspection stability will improve greatly when either color processing or pre-processing filters are properly applied to the image. The basics of image processing involve capturing a clear image.Ī color camera enables extraction of color differences in much the same way as the human eye.Ī variety of pre-processing filters are available to optimize image contrast according to the specific requirements of the application. Example Inspection of foreign matter in connector housing Multi-filtering combines several pre-processing methods in multiple stages to create an optimal image. * Only the flaw is extracted while the complicated shape of the target is ignored. Inspection of defects on the surface of rubber products while ignoring burrs Real-time differential processing: A captured image is compared with a registered image to extract only the differences. Expansion & shrink processing: Unnecessary projections are cleared and then the original outline of the target is recovered. Example Inspection of the flaws on an iron plate surface The influence of hairlines on the target surface is eliminated to project flaws only. Contrast conversion: Surface image adjusted to better detect flaws.
These functions can be used for both monochrome and color images after color binary processing and color shade scale processing have been applied. Machine vision is equipped with a variety of pre-processing functions to optimize images according to their various applications. This method offers stable results for inspection of different patterns or position deviation. Color shade-scale processing creates a gray image based on color information, resulting in a clearly visible, strong gray image on a black background. Pale color patterns are not easily recognizable with conventional gray processing (as shown on the left). Since images are processed with not only brightness but also color information, difficult applications, such as differentiation between gold and silver, are no longer a problem. Color shade processingĬolor shade-scale processing is a method to convert a color image with an enormous amount of data into a 256-level gray image by setting a specified color to be the brightest level(white). "Color shade-scale processing" is a pre-processing method developed to solve problems associated with the tremendously long processing times of color cameras as well as noise interference from excessive information and inconsistent illumination.
