Machine Vision (MV) is the technology and methods used to provide imaging-based automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance, usually in industry.
Area Scan cameras are ideal for still targets and capturing freeze frames of a scene. Area scan cameras capture 2-D images using a certain number of active elements (pixels), also called matrix cameras.
Line scan imaging uses a single line of sensor pixels (effectively one-dimensional) to build up a two-dimensional image. The second dimension results from the motion of the object being imaged. Two-dimensional images are acquired line by line by successive single-line scans while the object moves (perpendicularly) past the line of pixels in the image sensor.
TDI (time delay and integration) technology is a method of line scanning which provides dramatically increased responsivity compared to other video scanning methods.
Factory Automation (FA) lens applications differ from others that employ digital cameras, such as security or intelligent transportation systems (ITS) in that they are designed for high accuracy usually have controlled illumination and part location.
A telecentric lens is a compound lens that has its entrance or exit pupil at infinity; in the prior case, this produces an orthographic view of the subject.
Lighting is one of the most critical elements in a vision system and is in fact key to achieve stable and repeatable results. Incorrect illumination may result in extensive and time consuming image processing or, in the worst case, in crucial information loss. Machine vision lighting is defined as computerized light measurement.
PC-based vision systems generally consist of a PC with a Windows operating system. A frame grabber or Ethernet card in the PC interfaces to cameras to import the image
Software is a fundamental tool to design, build and operate a vision system.
