Humans have been blessed with perfectly amplified vision. But when it comes to machine, vision is the ability of the computer to calculate and have a comparative v vision for the better movement of the device. It is somewhat similar to the complex process of voice recognition. The two driving components of any vision system all across the globe is the sensitivity and the resolution. Sensitivity is the ability of any device to see in dim light, or to detect weak impulses at any invisible wavelengths, wherever it may concern. Whereas resolution is the very extent to which a machine can differentiate between objects. In a more laymen term, better the resolution, more confined are the field of vision. Sensitivity and resolution are very much interdependent, while all the other factors are held constant, there can be changes made in iGncreasing the sensitivity and reducing the resolution, vice-versa. Video cameras can be very much sensitive to a range of wavelengths way much wider than this. Machine vision is primarily the incorporation of computer vision into industrial manufacturing processes, although it does differ substantially from computer vision in an altogether framework. In general terms, computer vision revolves around image processing and having a better view altogether. Machine vision, on the contrary, uses digital input and output to manipulate mechanical components according to the requirement.

Devices that majorly are dependent on machine vision are often found at work in product inspection, as it holds importance in the nature of things to be checked upon. This is where they often use digital cameras or other forms of automated vision to perform tasks traditionally performed by a human operator, as humans tend to make errors and then there are repercussions for sure. Similarly each of these components serves its own individual function and can be found in many other systems as well, when working together they each have a distinct role in a machine vision system. All this is mostly in accordance with a particular way of working which is required when it comes to the vision impairment.

To understand how a machine vision system works, it may be helpful to envision it performing a typical function, such as product inspection. Firstly, the sensor in away detects if a product or material is present in the required quantity. If there is indeed a product passing through by the sensor, the sensor will automatically trigger a camera to capture the image, with a light source to highlight key features embedded to its system.

In case of processing an image, computer software must perform several tasks first to have a clear cut image stabilizing for having a clear cut vision as it is the sole purpose of having something like this in the first place. While in the process, image is reduced in gradation to a simple black and white format. In the next step, though, the image is analyzed by system software to identify defects and proper components based on the pre-requisite nature of the work. After the image has been finally analyzed, the product will either pass or fail inspection based on the machine vision system’s findings. All these steps significantly helps in the way humans check the quality of the product once it is been through the production part and is ready for disposal.
