Is it possible to increase the number of current targets in an object collection?
After adding 10 object target movies, we received an error "You have reached the maximum of allowed targets in the current target collection".
@Piyush, I havent tried this in Unity so not sure if it will work there.
What I had to do in the JS-PhoneGap version is to have a 2D multi-object tracker look for fake name tags (which act like QR codes), which then triggers and load the correct 3D Object Trackers. To figure out when a user "wants" to look at a new 3D target, I just use a basic timeout in trackable.onObjectLoss.
Here is the general steps:
i have 3 targets in a single .WTO. How can I use these 3 targets in the same way as multiple target image recognition (we are using unity3D)? Is it possible?
The easiest way to do this in Unity is to add a second ObjectTrackable child GameObject to the ObjectTracker. For each ObjectTrackable, make sure that the Target Pattern contains the name of the target it is associated with and add the appropriate prefab in the Drawable field.
So for ObjectTrackable 1 you would have the name of the object 1 target written in the Target Pattern as it was specified in the Target Manager and prefab 1 in the Drawable field. Same for ObjectTrackable 2.
You should use the exact same approach that you are using when recognising multiple images. So if you have a look at our example here for multiple image targets, you do exactly the same but you just replace the .wtc file with the .wto file and instead of AR.ImageTrackers you define AR.ObjectTracker.
I've modified the code for multiple image targets, however the multitracking always only detects one object. What else do I need to do to get multiple tracking to work?
I deeply apologize for the inconvenience but there has been a misunderstanding from my side. Multiple object recognition is possible but not at once. So there is nothing wrong at your code, this is the Wikitude SDK standard behavior. Again, I am sorry for the misunderstanding.
No worries. Thanks for double checking.
I think I will pursue using "2D detection that then triggers a specific object tracker" method to get a similar effect.
Hope multi object tracking comes soon.
can you please give suggestion how to do multiple object detection within a same scene
As our solution allows to add 10 objects to the object target collection, you can recognize up to 10 objects. Simultanious recognition of more than 1 object is not possible at the moment - so if there are 2 or more objects that you have in your collection in the camera view, only 1 will be recognized and tracked.
We unfortunately don't have a dedicated sample for this, but the priciples are the same as with image recognition and e.g. the sample for different image targets'
Can you post an example of tracking multiple objects?
I have two objects in my WTO file, and instantiated two AR.objectTrackable, one for each. However, the app seems to ever only recognize one object. What should I do?
Thank you Eva!
First question: we can have more trackable under an objectTracker ?
Another question: I've already imported a 3d Object (.fbx) in Unity3D: now i need to place this 3d object in a determinatig position of the scene (I'm using "Tracking Object" as an example): I saw that i can rotate e scale the object directly from my 3D software, but I can not move it in space, so that it is perfectly positioned above the framed object
. Do I have to do it from unity (within the asset, or in the trackable) or from the outside?
Do you have an example?
