iOS Camera does not track object

January 7, 2016 - 4:43pm #1

Hello!  I'm having a problem getting markers to track objects on my iPad.  In the Unity Editor on my MacBook I can get the object to track with my marker just fine.  When I deploy to iPad, my app boots up and the camera works, but the object doesn't track with my marker image.  I get this output in XCode.

Is there some setting I'm missing somewhere that would disallow object tracking specifically on iOS?  Thanks in advance for any help.

I'm using Unity 5.3.0f4, XCode 7.1.1, and an iPad 3 running iOS 8.1.3.

Hey guys, sorry about the delay on my answer.  Thanks for all your responses!

I turns out the image that I was using was just fine for the mac but the iPad couldn't detect it.  I tried a couple other images and found one that worked.  I guess the iPad camera is just low quality or something.  I didn't expect there to be such a difference between the webcam on the macbook that I'm using and the camera on the iPad.

had the same problem today with XCode 7.2 iOS 9.2 and found the solution: In XCode:


You need to go to your projects Build Phases -> Copy Bundle Resources, click the + sign, then click Add Other... and then select folder QCAR located in *ProjectRootPath*/Data/Raw/. Cheers!

You might try including the stones and chips targets in your custom dataset as well. If the custom targets are tracking in Unity PlayMode, you may want to add some Debug.Log() statements in the TrackableEventHandler and watch Xcode output to see the logs.

I am.  Using the example project and the provided images works for me and the images track on my iPad.  It doesn't work with my own custom marker image though.  I have made sure to check the box under the Database Load Behaviour script to properly load the dataset.  I checked both the dataset and the activate boxes.  I confirmed that my custom marker image works on my MacBook in the Unity Editor but not on my iPad.

Are you able to get the ImageTargets 5.0.10 sample app working okay?
