Composition of machine vision system

The machine vision system can detect components, where the optical device allows the processor to more accurately observe the target and make effective decisions on which components can pass and which needs to be discarded; The combination of software directly guides the manufacturing process.

Although machine vision applications vary, they all include the following processes;

■ Image acquisition

The optical system collects the image, and the image is converted into an analog format and transferred to the computer memory.

■ Image processing

The processor uses different algorithms to improve the image elements that have an important influence on the conclusion.

■ Feature extraction

The processor identifies and quantifies key characteristics of the image, such as the location of holes on the printed circuit board or the number of pins on the connector. These data are then transferred to the control program.

■ Judgment and control

The control program of the processor makes a conclusion based on the received data. For example: These data include whether the hole on the printed circuit board is within the required specifications or how an automated machine must be moved to pick up a part.
