Machine Vision
In machine vision the lens focal length sets up the fixed relationship between the field of view and the working distance. Field of view is the area of the inspection captured on the camera’s imager. The size of the field of view and the size of the camera’s imager directly affect the image resolution (one determining factor in accuracy). Working distance is the distance between the back of the lens and the target object.

Famous quotes containing the words machine and/or vision:
“The machine is impersonal, it takes the pride away from a piece of work, the individual merits and defects that go along with all work that is not done by a machine—which is to say, its little bit of humanity.”
—Friedrich Nietzsche (1844–1900)
““The god has not yet answered to our pity
For the black vision and tangle in her brains,
Nor is there knowing soever in the city
Of the red histories that throbbed in her blue veins.””
—Allen Tate (1899–1979)
