VuMark Instance

Hello,

I am build an Untiy application, which is using VuMarks. I have created VuMarks that can symbolize up to 999 numeric id's, but actually I am only using a few of them.

The problem is, that the marker are detected, but mostly only 2 marker instances are loaded into the scene. Sometimes it loads a third one. Marker instances in Unity means the GameObjects named "VuMark" and "VuMark(Clone)". If these 2 or 3 instances are loaded, any new marker will be detected and "OnVuMarkDetected(VuMarkTarget target)" is called, but there is no new instance loaded of "VuMark(Clone)".

And sometimes it is parsing the wrong ID from the marker, but I think this is caused by the upper problem.

The next thing I am going to try is adding the VuMarks by myself from the Prefabs.

 

I hope someone could help me with that.

Thank you already

I have the same question as well. I am trying to understand the behavior of how VuMark(Clone) got generated. 

Well 7 is much better than 2 or 3.


Maybe it has something to do with how many values are decoded in the marker?
Or the datatype is causing these different results? I am using the numeric ID´s.

I am using numeric ID as well. 

 

"I tried to add the marker instances by myself." --> The system is adding the instances by itself. I wish it doesn't add the "Clone" instance by default. It is blocking my project currently.

Hello Simwo and iDream0316,

Is the issue you're both facing related to not being able to detect multiple VuMarks at once? Or is it related to the existence of the "VuMark(Clone)" object?

Thanks,

Hello Strasza,

in my case its more the not exitsting of the "VuMark(Clone)"-Instance in Unity.

Vuforia is always able to detect a new marker and its ID, if it appears in the cameras view. 

But there are only 2-3 "VuMark(Clone)"-Instances created in Unity.

Simwo,

Apologies for the delayed response.

Are you wanting to detect more than 2-3 VuMark simultaneously and are unable to, or is the lack of clones being created causing another issue?

Thanks,

Hello Straza,

yes, I would like to track more than 2 VuMarks simultaneously and I am not able to do this.

But it is not necessary, in every case, that the VuMarks are in the cameras view at the same time.

Hello,

an short update on this issue.

I discovered, that the problem is reduced in Untiy version 2017. Sometimes it also occurs here, but mostly it works fine, at least in the editor.
