Ground Plane not Working

May 13, 2019 - 5:56pm #1

Hi,



I am using Unity 2019.1.2 and Vuforia version 8.1.11. I followed the instruction in (https://library.vuforia.com/articles/Solution/ground-plane-guide.html) and I am not able to make it work. I looked at some Youtube tutorial to double check if I missed anything but I did not forget anything. I test it by running in Edit mode with my webcam. I am able to do use Image Target so I know some feature is working.

I am not even able to see the DefaultPlaneIndicator through my webcam. I have an ARCamera, Ground Plane Stage with a capsule as a child and a plane finder. I put the reference of the ground plane stage in the plane finder just like in the tutorial. I print out the image target and try to use the camera to make it work. Any suggestion of what I am missing?

Hello,

I retested Ground Play in Play Mode using the versions you provided below. I found no issues as it worked correctly.

Note that in order for Ground Play emulation to work properly in Play Mode, you *must* print and use the target "Emulator Ground Plane.pdf" in Assets\Vuforia\Databases\ForPrint\Emulator\. This is because typical consumer USB webcams *do not* have integrated IMUs, so they cannot support the Ground Plane feature natively. The target above must be in the webcam's field of view in order for Vuforia to emulate the Ground Plane feature in Play Mode.

I did notice a typo in the article's instructions, particularly the location of the aforementioned PDF, which I will work to have corrected.

Thanks,

Hi medabit,

 

I tried the Vuforia core samples and I was not able to make the ground plane work in play mode. I ran the ground plane scene, put the ground plane image on the floor and aim with my webcam on it but it won't detect it. Is it possible that someone try it with the latest version of unity and Vuforia engine? From what I see from other posts I am not the only one facing that issue.

 

Kind Regards

Hello,

I strongly suggest that you also review the Vuforia Core samples on the Unity Asset Store for best practices when created a Ground Plane experience.

The documentation you've referenced is meant to provide an overview of the feature, but may not represent *all* the steps required to get the feature to work in your project. Thus, I believe the Core samples provide the next level in documentation for best practices.

If you cannot get it to work with the Core samples, please let me know.

Thanks,

Vuforia Engine Support
