MACHINE VISION

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

COMPONENTS OF MACHINE VISION

COMPONENTS OF MACHINE VISION

Light source-LED, Fluorescent, Halogen lamps

Lens – Telecentric , Macro lensSensors – Optic ,Magnetic typeVision processing unitCommunication unit

WORKING PRINCIPLE

7

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.
