Visual Inspection

Visual inspection relies on technologic instruments instead of raw human eyes to measure targets and draw conclusions. Imaging devices, such as CCD and CMOS, are used to capture the target into image signals, and then the signals are sent to the image processing system and converted into digital signals based on the pixel layout, brightness, color, etc. A set of algorithms are used to draw conclusions and tell features of the target, which helps decide the site equipment operations. Visual inspection adds significant values to production, assembly, or packaging for quality inspection and control. In this case, no defect shall find its way to consumers.


Production is greatly automated and injected with much more flexibility with the help of visual inspection. In scenarios where hazards may defy human attempts or human senses simply fail, technological devices serve well to complete the tasks. In scenarios involving large scale industrial manufacturing, visual inspection beats human eyes for quality assessment and control with higher efficiency, more accuracy, and greater automation. In this case, visual inspection efficiently integrates information and serves as the fundamental technology for computer integrated manufacturing.
