Object tracking work perfectly with TEST APP but doesn't work in Unity3D

August 8, 2017 - 5:59am #1

Dear all,

we have very strange problem with Object Tracking recognition. We made all steps with Android App to create tracker file and test it with the same app: it work perfect. When we export the tracker file for Uinty3D editor and recompile it in Xcode the recognition start very very difficult, but with the Vuforia test app work and start to track perfectly.

What is the problem? Is there a solution to have the same tracking like Vuforia test app?

Thanks in advance

Is the object you are scanning in something that is commercially available and/or something we would be able to get? This would allow us to test the process internally and try to reproduce the issue you're seeing.

Additionally, in our labs we utilize four primary strategies for creating an optimal Object Target scanning environment:

  • All background surfaces are colored at 18% gray. An easy, off-the-shelf solution is to buy bed sheets near this color and drape everything in the environment that could be seen by the scanning device's camera.
  • No direct lighting. We use light boxes and/or diffusers to eliminate direct lighting upon the object and minimize any spectral reflections.
  • Utilize a 360 turntable to re-orient the device. This is especially helpful when you've set your environment to near ideal conditions within a limited area. You can spin the model and scan in 360 degrees without having to move around it.
  • Be sure that the environment in which you’re testing (via the Object Scanner app ‘test mode’) is the same in which you’re verifying tracking (via the sample code). Environmental factors such as lighting, shadows, spectral reflections, etc. can negatively affect tracking performance, so awareness of how the environment is interacting with your model is important for qualifying performance.

Can you confirm that you are following the above tips as well?

Thanks,

We used Samsung Galaxy S6. This is a very mistery. Object tracking It's impossibile to use and the very sad thing is that your app works perfectly. If you were able to even run the plugin for unity properly we could meet the customer with an excellent tracking system. Unfortunately, for the moment, it was not possible.

If you have a solution we are here to try to have the same results in unity like your scanner app.

One of the common problems we see with using the scanner app is not using the recommended devices, Samsung Galaxy S6 and Galaxy S7. Using these devices to scan in the object target will greatly improve the detection.

Hello, the steps are:

  • use your Scanner app for Android to make the od file
  • import od file in your online platform and export .unitypackage
  • import unitypackage in unity scene and setup it
  • compile from unity for iOS platform to generate xcode project
  • open xcode project in xcode and run in an iPad

that's all. The result of the recognition and tracking it's totally bad (the start tracking of the object it's very difficult and when the tracking started it's totally unstable), but from your scanner app the green cylinder appears immediately and the tracking it's very stable.

What is the problem? I saw that in your forum there are a lot of people with the same problem from years. What is the different between our project and you scanner app? At the moment we have serious problem with our clients to explain these diversity.

Thanks for your support

Hello ubiqstudio,

What do you mean when you say you export the tracker file for Unity and recompile it in XCode? Are you referring to the XCode project that gets generated when you build for iOS devices in Unity, or are you taking the script from Unity and putting it into a separate XCode project?

Thanks,
