How to implement a bolt and screw inspection system?

[rostamiani]

I want to implement a Bolt and Screw inspection system using a camera. For example finding screws withouts enough grooves or without a head.

I'm familiar with image processing algorithms but I don't have a global overview about the approach. 

From where should I start?

This is my plan:

1. Find screws by Object Detection

2. Find head and count the grooves on the bolt.

Thanks

I think Vision Assistant is really helpful for you : D

It has "Solution Wizard" and you can find some example of vision application!

I believe you can develop the application with NI Vision system.
