What is a vision camera? What is machine vision and how can it help? It can be useful to understand how machine vision works. If you understand the basics of what a vision camera is and how it can help, specific problems will become easier and clearer. People are often confused about what machine vision can and cannot do for a production line or process. Understanding how it works can help make decisions about whether it solves application problems. So what exactly is machine vision and how does it work? Let’s explain it and. Especially using the vision camera.
Machine vision and the vision camera explained
A definition will now first follow to make clear what both mean exactly. Machine vision is the use of one or more cameras to automatically inspect and analyze objects, usually in an industrial or production environment. The data obtained can then be used to monitor a process or production activity. And where can it be applied, for example? A typical application may be on an assembly line. This is because after an operation on a part has been performed, the vision camera is triggered to capture and process an image. The camera can be programmed to check the position of something. For example, of the following things:
- The color
- The size
- Its shape
Or, for example, to see whether or not there is an object present. In addition, once the product has been viewed, in most cases a signal is generated to determine what to do with it now. The part can then be approved, then it goes further in the production process, or it can be rejected, then it is delivered in for example a container. Furthermore, typical applications are the following. Test and calibration, machine monitoring, data collection, sorting and counting, as well as robot and machine guidance.
What is the vision camera and what are its functions?
It is also interesting to know what the functions of the vision camera are, but especially in the field of lighting. Lenses and lighting, the image sensor or camera, the processor and a method to communicate the results are the four most important components of a vision system. The lens captures the image and presents it to the sensor in the form of light. In order to optimize the vision system, the camera needs to be tuned to the right lens. There are many different methods to apply lighting to the image. The direction the light comes from is important, but not only the direction. Brightness and color also play a very important role. Although lighting is an important part of getting a good image, there are of course other things that influence the amount of light that an image gets. The lens has an adjustment called the aperture, which is opened or closed to allow more or less light into the lens. In combination with the exposure time, this determines the amount of light on the pixel array before even exposure is applied.
