Maximum targets that can be recognised

February 25, 2013 - 2:43am #1

I read some limitations on the number of images that can be tracked while using Image Targets. 

{ if using vuforia sdk 2 maximum limit is 100 . It can in one or multiple active data sets .

In earlier versions there can be only one dataset active at a time, but there is no limit on the Number of targets. 60 is the maximum recommend considering performance . } -> please correct if my understanding is wrong.

Also will perfomance be affected as number of targets increase ? ie if my app supports only 10 images will it have better performance than supporting 60

 

Now i was considering frames. Recognising frames. So vuforia has 512 built in frames ( am i wrong here again ? )

Is there a way user can add unique frames to this deafult set of vuforia. ie can i make my app recognise 100 frames for eg ?

 

please help me with answers

Hi, the access keys will not change; you can add as many targets as you want to an existing Cloud Database and it will keep working also with the new images.

Thank you for confirming my option. I was going through the cloud database option.

Can you please answer this question.

After uploading few images , i cretaed an access key file and integrated with app.

Now if i add some more images to the same cloud database , will these access keys change .

ie can i add images without changing my app.

 

Thanks for your support

Yes, the Cloud feature could be a very good option if you plan to have many targets.

Thanks a lot for the quick reply . I am checking on the cloud database in vuforia 2 if that can help  me.

Thank you

Hi, answering your questions here below:

  • { if using vuforia sdk 2 maximum limit is 100 . It can in one or multiple active data sets .

    In earlier versions there can be only one dataset active at a time, but there is no limit on the Number of targets. 60 is the maximum recommend considering performance . } -> please correct if my understanding is wrong.

Correct.

 

  • Also will perfomance be affected as number of targets increase ? ie if my app supports only 10 images will it have better performance than supporting 60

Using fewer targets (e.g. 10 vs. 60) could result in better performance (although testing on your specific case is the only "practical" way to see if the performance difference will be noticeable)

 

  • Is there a way user can add unique frames to this deafult set of vuforia

​No, you can only use the 512 Frame Markers set;  for customly-defned targets/markers, you should consider Image Targets. 

 

I hope this helps.
