Vision Based Post Letter Sorting

Vision Based Post Letter Sorting 

          Vision Based Automation system is the most trending technology across the globe in the past few years. Each and every industry stared using vision based automation system in their major process like Manufacturing, Quality checking, Material Inspection,etc. Using this valuable technology, here we tried post card sorting system using image processing in NI LabVIEW. 

              

              The Main Objective of this experiment is to sort the post cards automatically using Vision system. The experiment was tried after realizing a situation in Indian Postal Network. In India, the post offices process lac's of letters in a single day. It is not an easy job to sort all the letters manually but they are still doing it. In order to over come such situation, we tried this experiment to put an end to this process.  

The major components used in this experiment are 

1. Conveyor

2. PC with Labview installed in it.

3. Sorting arrangement

4. Camera

5. Motors

6. IR sensor

7. PIC 16F877A Controller board

8. DAQ card

Step1: The post cards should be dropped in the conveyor.

Step2: The cards will move in the conveyor and when it reaches the camera location, an IR sensor detects the card and stops the conveyor.

Step3: Now the camera will take an image of the post card and starts conveyor again after few seconds. 

Step4: The Image will be processed in Labview to get the results.

Step5: The Pin code in the post card will be found using image processing Labview.

Step6: Then according to the pin code the labview will send trigger to the controller board through DAQ card.

Step7: The controller board will rotate the sorting arrangement to receive the post card in appropriate box.

And the process continues.
