Production system, is called for short transfer matic；Along with automobile, rolling bearing, miniature motor and sewing machine
Deng industrial development, machine-building starts to occur transfer matic, occur that building-block machine is certainly the earliest
Moving-wire；Before twentieth century twenties, first it is to occur in that flowing water is raw in the automotive industry
Produce line and semi-automatic production line, develop into transfer matic subsequently；Transfer matic is used to carry out producing
Product should have sufficiently large yield；Product design and technique should be advanced, stable, reliable, and
Keep in long period being basically unchanged；Use transfer matic can improve labor in productions large quantities of, a large amount of
Dynamic productivity ratio, stabilizes and increases product quality, improves working conditions, and reduction produces floor space,
Reduce production cost, shorten the production cycle, it is ensured that production smoothing, have significant economic benefit；
Wherein, in automatic assembly line, 2D visual identity is the capital equipment of image data acquiring and process；
Machine vision is commonly defined as automatically obtaining analysis image and obtains describing a scenery or controlling certain
Planting the data of action, its essence is to make computer have to recognize from single width or serial two-dimension images array
Knowing the ability of ambient condition information, this ability will not only cause a machine to the several of perception surrounding objects
What information, including it shape, position, attitude, motion etc., and they can be retouched
State, identify and understand；For work robot in particular circumstances, right in order to complete
The operation of target object i.e. " identifies to capture and places " action, and target object is positioned information
Acquisition be necessary；Image processing method of the prior art is more numerous and diverse, and can not be fine
Ground forms one and identifies system.
Summary of the invention
