Recognize QRcode.

By hanzhen18 on Wed, 02/26/2014 - 09:00

Happy New Year, Everyone!

I wish new year will bring us abundance of joy, health, and prosperity!

I have one problem in my AR app developing.

I need to specify if the image from camera is qrcode or not and if it is qrcode, need to show some buttons over it.

I tried to perform this by using one qrcode as a target, but since the vuforia sdk has very good recognition performance and qrcode is not so good to use as a target image, only few qrcodes are recognized as matching result.

 

All I want to do is to show buttons when the camera focuses any qrcode.

Is there anyone can help me with solving this problem?

 

Looking forward to hear your answers soon.

 

Thanks.

At present Vuforia does not support QRCode recognition, though if you want this added please submit as a feature request.

Thanks, NalinS

I am sorry but, I had already achieved recognizing qrcode by integrating zbar with qualcomm.

I grab video frames from camera and use them to get decoded result of the qrcodes and it works greatly.

Hello NalinS

Thanks for your helpful message.

 

I was highly appreciated to your help.

I use zbar to recognize qrcode and I don't think it provides rectangle of qrcode.

Have you guys met some kind of barcode reader add-in for brower which could let us recognize QR code though the brower, without taking the image to server?

Developers have successfully integrated QR code readers in their Vuforia apps, you should be able to find some examples if your do a search of the forum.

Also try posting in the forum for the SDK version that you are using, and you may get some additional recommendations.

As DavidBeard said in his previous message, it is possible to use QR codes with Vuforia (many developers have succeded in doing this);

basically, you need to generate an Image Target via the Target Manager, using the QR code image; then you can use it like any other Image target.
