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:
“But it is found that the machine unmans the user. What he gains in making cloth, he loses in general power. There should be a temperance in making cloth, as well as in eating.”
—Ralph Waldo Emerson (1803–1882)
“The failure to read good books both enfeebles the vision and strengthens our most fatal tendency—the belief that the here and now is all there is.”
