Robustness: Another good test is to see the light source if the minimum sensitivity of the position of the component. When the light source is placed in the camera field of view of different areas or different angles, plastic mold protection, the resulting image should not change. Strong directional light source, increasing the likelihood of a specular reflection occurring on the highlighted area, which is not conducive to the back of the feature extraction. Good sources need to be able to make you need to look very obvious characteristics, in addition to the camera is able to shoot the parts, the good light source should be able to produce maximum contrast, brightness and position changes enough parts insensitive. Choose a good light, and the remaining work would be much easier. Specific source selection method in that trial experience visual detection is to use machines instead of human eyes do measure and judge. Visual inspection means to be ingested by machine vision products (ie, the image pickup device, two kinds of sub-CMOS and CCD) target is converted into an image signal, sent to a dedicated image processing system, mold protection, according to the pixel distribution and brightness, color and other information , converted into a digital signal; imaging systems for various operations on these signals to extract target features, and then based on the results of determination to control the scene equipment movement. It is a valuable mechanism for the production, assembly or packaging. It is invaluable in detecting defects and prevent defective products are delivered to the consumer in terms of functionality.
