How Does Machine Vision Work?
Machine vision is the application of a camera or several cameras to check and analyze objects automatically. Machine vision systems mainly depend on the digital sensors in industrial cameras. There are equipped with technical optics to obtain external vision, thus the computer can process, analyze, and measure various features for decision making. Machine vision is preferred to be applied in an industrial environment due to its high efficiency. Lots of manufacturers use automated machine vision instead of human inspectors because it is better suited to repetitive inspection tasks. It is faster, more objective, and works continuously.
Custom Machine Vision Lens & Illuminator From Canrill
Canrill catalog or product list on website only presents our most common models. Canrill also has an extensive of non-standard models in production. In addition, Canrill Optics offer customized machine vision lens or illuminators upon detailed request from customers. With rich experience both in optical design and mechanical engineering, and also our own optical factory and mechanical factory, Canrill is able to react fastest from design to prototype to mass production.
Canrill's record is 12 days to produce a complete imaging lens including design time.
Working Principle of Machine Vision System:
Lens Object FOV is a little larger than customer required FOV.
Lens Image FOV is equal or larger than camera sensor size.
Mag below 1X refers to low mag, above 1X refers to high mag.
There Are 3 Important Factors That Contribute In The Selection Process:
Image FOV, the sensor size of camera
Object FOV, the size of observed object
Working Distance
By image FOV and object FOV, the magnification of the lens can be acquired, that is image FOV/Object FOV.
Knowing the above, we can select a suitable lens optical from the existing product list.
Example:
Camera:1/2.5’-5MP
Sensor size: 5.7*4.3mm
FOV: 60*40mm
To pick a suitable lens, first to calculate the mag, 5.7/60=0.095X, 4.3/40=0.1075X.
Lower mag will be picked so as to cover full FOV.
From Canrill product line, Canrill fouth generation PTL series PTL-08 series is the most suiable, and the mag of XF-PTL09228 is 0.0847, is the closest figure to 0.095X.
Thus XF-PTL09228 is selected.
Machine Vision System Applications
Canrill Optics provides the machine vision illuminator and lens products usually used in guidance, inspection, gauging and identification.
