Also, a human cannot catch all the tiny defects such as cracks, etc. To solve this problem, industries are now adopting visual inspection systems which can not only enhance the quality of inspection, but also give a good overview of the production line and classify the collected defects for further reference. They rely on industrial cameras containing digital sensors which acquire images for computer software and hardware to analyze, process and measure all the characteristics and then decide if a product is completely fit or not.

They also calculate objective measurements such as plug gaps for electrical appliances, or level of drinks in bottles etc. Major components of visual inspection systems are: Lights: for illuminating the part which has to be inspected. It’s essential to focus on a certain feature so that the cameras can catch it. Lens: Lenses are meant for capturing images and presenting it to the sensors. Sensors convert the images into digital images which can be processed for analyzing. Vision Processing.
