MACHINE VISION
The process of extracting information from visual sensors to enable machines to make intelligent decision.

COMPONENTS OF MACHINE VISION
Light source-LED, Fluorescent, Halogen lamps
Lens – Telecentric , Macro lensSensors – Optic ,Magnetic typeVision processing unitCommunication unit

WORKING PRINCIPLE

WORKING PRINCIPLE1. A camera takes a picture of the object to be
tested in the presence of lens with suitable intensity of light source, and sends it to a computer for image processing.
2. The computer will define and analysis the characteristics of image.
3. After analysis the computer system will communicate with rejection unit if any defects in the part, or else if it is defect free it will send to the next station for processing.

APPLICATIONS OF MACHINE VISION SYSTEM
10
MEASUREMENT
In measurement applications the purpose of the vision system
is to measure physical dimensions of the object. Examples of physical dimensions are distance, diameter, curvature, area, height, and volume.
Example: A camera measures multiple diameters of a bottleneck
11
COUNTING Counting is another typical machine vision application Basically counting means look for number of parts over
number of features on a part, this allows us to locate missing part and ensure the products are assembled properly.
Example 1: counting of holes on the aluminium flange.
12
COUNTINGExample 2: Identifying the presence or
absence of the part.
13
LOCATIONMachine vision also used to report
the location and orientation of the parts.
14
DECODING It is an identification application in which the
vision system reads various codes and alphanumeric characters (text and numbers) and decodes the codes to get the product features .It is used to record information as historical data, track products ,validate data, verify correctness of data and verify the product.
15
ADVANTAGESMachine vision system works more faster
than manual system.Machine vision is consistent.Perform beyond human vision High repeatable in controlled environmentNo fatigue – 24/7ReliableGood for unsafe and hazardous
environmentOperate well in space constrained
environments
16
ADVANTAGES
17
CONCLUSIONMachine vision is less risky, reliable to
use.It enables high speed examination of
defects in products.The quality products can be obtained
bythe incorporation of machine vision
system.
