  Machine vision or MV is a method or technology which is used to deliver imaging-based automatic analysis and inspection for applications such as process control, robot guidance, and automatic inspection. Machine vision is a term that includes a variety of technologies, hardware and software products, actions, and integrated systems. Machine vision can be considered different from computer vision. Machine visions are primarily of two types – 2D (two dimensional) and 3D (three dimensional). The usage of 2D or 3D machine vision systems depends upon the application they are used in. In 2D machine vision, a 2D map (X, Y) of the reflected intensity is taken and then it is processed. The processing usually consists of comparing contrasts (variations in intensity).  2D machine visions are conventionally used for applications such as label orientation, barcode reading and printing verification. On the contrary, 3D machine vision systems deals with all the thr...
