Roborealm and Vb.net

Please Help Me.... This is my activity in school.

I presume you have some coins in your currency. I would like you to take about 4 different coins. And place them on a white background in front of a webcam no more that 1024 X 768, one at a time, at a range of around 200mm. What I would like is an app that with a press of a button can determine which coin is present and return a number or text to represent that coin to the user. Use roborealm as the image recognition system and interface it to vb.net. The coin should be recognized regardless of what side its on and where in the field of vision it is.

How can I supposed to do this. Any body help, and connect roborealm to vb.net . My vb.net version is 2008.. Thanks a lot

Nino,

Can you take a couple pictures of the coins and post them here? We can then help with a possible robofile. The one we did do was based on the size of a circle. If you plan to use texture you will need to have a look at the following lighting technique:

and specifically Axial lighting.

If you can use size, see the attached robofile which does just that. (be sure to download the latest RR version for this to run 2.47.11 ... should amount to $5.82 USD.)

For integration with VB.Net see

or alternative methods at

Hello ,

Thank you for your reply. In the tutorial from this link http://www.roborealm.com/help/API.php .


Can I used those commands in vb.net to recognize the coins.? And what are the connection string to use those commands?

I have uploaded sample pictures below.

Thanks,

Nino

Nino,

Those would be used to set the image in RoboRealm, so they may be the first part of the recognition process unless you are using a webcam directly in RoboRealm. It depends on how you expect to accomplish this.

Also, in you coin image, are you looking to recognize JUST the one coin or all coins in the image? It was not clear from your image if you are creating a generic coin recognition system or if you are looking for a particular coin among a bunch of coins.

What should I do and the codes to interface it to vb.net?

Thanks.

Nino,

Check the vb.net examples in the api example download. That will help you get started with interfacing vb with RR.
