Corner Detection on Video Background

By matiasjaure on Fri, 06/29/2012 - 22:01

Hi! I want to make a corner detection on the video background and create a virtual button on the detected corners. I have seen corner detection on openCV, but l am not sure if there is a way to use openCV with Vuforia. So, if someone could give me some guidance with this it would be highly appreciated. Many thanks!!

 

Regards,

Matias

I would like to see some support articles on integrating Qualcomm's FastCV with Vuforia AND Unity as well!

Do you know if it is possible?

Hi Matiasjaure

At present there are no guides for how to integrate these two SDKs, but theoretically there is no reason why they cannot integrate.

Just so I understand correctly is it that you want to understand where the corners are for an image target?

What I want to do is to detect the corners using opencvsharp, so it would be nice to know where I can get the image from the camera, pass it to opencvsharp and it will return the image modified with the corners detected.

You can also obtain the pixels of the Image directly, as a byte array, using the following code which is implemented as a tracker event handler - i.e.

I think that you'd have to wrap the FastCV libraries as a native Unity plugin, which will require Unity Pro. Also FastCV currently only support Android. But if these two requirements don't dissuade you, I'll look into the best approach to integrating FastCV.
