7. WORKING PRINCIPLE
1. 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.

9. 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. COUNTING
Example 2: Identifying the presence or
absence of the part.
12

13. LOCATION
Machine vision also used to report the
location and orientation of the parts.
13

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. ADVANTAGES
Machine vision system works more faster
than manual system.
Machine vision is consistent.
Perform beyond human vision
High repeatable in controlled environment
No fatigue – 24/7
Reliable
Good for unsafe and hazardous
environment
Operate well in space constrained
environments

16. ADVANTAGES

17. CONCLUSION
Machine vision is less risky, reliable to
use.
It enables high speed examination of
defects in products.
The quality products can be obtained
by
the incorporation of machine vision
system.
