Augmented Reality with symbols
Hey guys,
I need to recognize symbols with a camera at runtime. I tried to use the vuforia unity plugin and the Metaio sdk too. The problem is that the image of my symbols are not complex enough to both plugins to be recognized easily. I have 8 symbols and there are only 3 of the 8 symbols that can be recognize. I linked a picture of my symbols. In Metaio even if I reduce the similarityThreshold, it doesn't get better. Do you know anything else that would be better ? Is AR the way to go ?
Thanks a lot for your time.

You can use Vuforia Frame Markers ... since if recognized the square around ( see image below ) and you can put any image inside ... you will have 256 ID's to use
looks like this ... remember to print with a white border after the black one
I did not found the official source Image , but i already had at my dropbox ... i never find them to download when i need ... Frame Target Images from DropBox
Hey Thanks, a lot for the awnser. I am checking this out right now. The only thing I'm not sure is what if my symbols will be printed on little pieces of wood, so there will always be a bit of a different background on each pieces. Also I did not understand perfectly the frame markers. Can I create custom one ? Like to try with a full white squared or I have to use one of the 512 provided ? Thanks a lot for your help.
You will have to use one of the 512 ... but you can choose the prettiest one =c.
about the background you can put anything inside , the vuforia will not check for the background ... here is how i think it does:
1 - They look for the black square ( making a white square after the black will help the tracking ... it ill be easy to see )
2 - They look for the pattern of the black / white little squares ( you can have anything in the background , BUT you need to help the software to "find" the little squares )
ps: see that i used a full white background ... this tell me that your image must be easy to see at least the black squares or maybe just the white ... maybe both being easy to find, will increase perfomace ...
you will need to test alot to find the better that work for you ...
Alright thanks a lot. I will check this out. Thanks a lot for your time :)
