What is Machine Vision and How Can It Help?

People are often confused about what machine vision can and cannot do for a manufacturing line or process. Understanding how it works can help make decisions about if it will resolve problems with the application.

So exactly what is machine vision, and how does it work?

Machine vision is the use of a camera or multiple cameras to inspect and analyze objects automatically, usually in an industrial or production environment. The data acquired then can be used to control a process or manufacturing activity. A typical application might be on an assembly line; after an operation is performed on a part, the camera is triggered to capture and process an image. The camera may be programmed to check the position of something, its color, size or shape, or whether the object is there or not. It also can look at and decipher a standard or 2-D matrix barcode or even read printed characters.

Five Machine Design Challenges and How Motion Controls Help

Commercial challenges for machine designers are being address by the motion control industry. See how these five advances can help with motion control designs.

Motion control system designers are under pressure to differentiate offerings in an increasingly commoditized marketplace in a wide range of applications, such as benchtop laboratory automation, plant-floor material handling, and heavy-duty construction vehicles. Many original equipment manufacturers (OEMs) ask control component vendors for help, seeking more functionality in less space, faster time to delivery for prototypes and products, and more control and flexibility over price points with seamless integration and operation.
